In the exclusive enclaves of Southlake and Westlake, a standard guest house is no longer enough. Homeowners today are looking for architectural continuity, structural permanence, and the kind of high-end finishes that mirror the sophistication of their primary residence. Whether you call it a casita, an in-law suite, or an accessory dwelling unit (ADU), the goal remains the same: creating a high-value extension of your estate that serves your family for generations.

At DFW ADU Pro, a division of Boomer Group Inc., we specialize in the "missing middle" of luxury construction: designing and building detached units that don’t just sit in your backyard but belong there. For families in Tarrant and Denton counties, the decision to build is often driven by a need for multigenerational living, providing a private, dignified space for aging parents or independent quarters for adult children.

The Masonry Advantage: Beyond Curb Appeal

When building in high-value North Texas neighborhoods, "matching" is the gold standard. A detached structure that looks like a pre-fabricated shed or a temporary modular unit doesn't just look out of place: it can actively hurt your property value.

Our brick and stone ADU designs are engineered for architectural matching. By utilizing the same masonry profiles, limestone accents, and mortar colors found on your main home, we ensure the new structure feels like it was part of the original master plan.

Why Brick and Stone?

• Structural Permanence: Unlike temporary structures, our ADUs are built on engineered slab foundations, ensuring they stand the test of time in the shifting North Texas soil.
• Thermal Efficiency: Masonry provides superior insulation against the Texas heat, reducing energy costs for your in-law suite.
• Aesthetic Integration: From Oklahoma Cream limestone to Artisan Gold brick accents, we use premium materials that reflect the heritage and luxury of Westlake and Southlake architecture.

Luxury Finishes: The Interior Experience

A luxury ADU should feel like a boutique hotel suite, not a basement apartment. In Southlake and Westlake, the interior expectations are high. We focus on mid-price-point, high-value solutions that deliver a premium feel without the $500-per-square-foot price tag of a full custom estate.

For a typical 500 to 800-square-foot plan, we emphasize features that maximize the sense of space:

1. Vaulted Ceilings & Timber Beams: Creating vertical volume makes a smaller footprint feel expansive.
2. Chef-Inspired Kitchenettes: We utilize quartz countertops, custom-built cabinetry, and high-efficiency stainless steel appliances.
3. Spa-Like Bathrooms: Walk-in showers with designer tile and premium fixtures provide the comfort your guests or parents deserve.
4. Hardie Siding Accents: While the exterior is dominated by brick and stone, we often integrate Hardie board and batten or horizontal lap siding in warm trend colors like sage green or warm gray to add texture and modern flair.

As a leading guest house builder, we understand that these details aren't just for show: they are the functional elements that make a home livable.

Designed for the North Texas Lifestyle

One of the most requested features for our guest house builders in Keller, TX and the surrounding areas is the integrated porch. In the Texas heat, a functional outdoor space is essential.

Our designs prioritize covered front porches as additional living rooms. By including ceiling fans, recessed lighting, and enough space for rocking chairs, we create a spot where a grandmother can sit comfortably and watch her grandchildren play in the yard: the very heart of multigenerational connection.

Navigating the Bureaucratic Learning Curve

The biggest hurdle for many homeowners in Southlake and Westlake isn't the design: it’s the paperwork. These municipalities have strict zoning laws, specific setback requirements, and rigorous inspection schedules.

This is where DFW ADU Pro excels. As a top 1% ranked Texas contractor based on verified permit history, we handle the entire city submittal and inspection process. We are your turnkey solution, managing everything from site feasibility and architectural design to full permit management.

We’ve been building in Tarrant, Denton, and Wise counties since 2001. We know the local codes, the local inspectors, and the local challenges. When you partner with us, you aren't just hiring a crew; you’re hiring decades of local expertise.

Investment and Property Value

Building an ADU is a strategic financial move. In markets like Southlake, adding a high-quality brick-and-stone guest house can significantly increase property desirability. It transforms a standard residential lot into a multigenerational estate.

For families considering multigenerational home additions in Keller or Westlake, the cost of an ADU (typically ranging from $125,000 to $150,000 for a well-appointed 500 sq ft plan) is often more cost-effective than long-term assisted living or purchasing a second property. It keeps the family together while providing everyone with their own "front door."

We aren't here to build an intimidating monument; we’re here to build a home for the ones you love.

The other morning, our Director, Bruce Laing, was making his usual drive through Southlake and Westlake. If you’ve spent any time on Highway 114 lately, you know the stretch. It’s the heart of our community, a corridor that connects our families, our businesses, and our homes.

But Bruce noticed something that didn't sit quite right. Between the rolling hills and the high-end developments, the medians and shoulders were: to put it lightly: a bit of a mess. Road debris, overgrown weeds, and wind-blown trash were piling up where there should be pristine Texas landscaping.

Now, Bruce isn’t one to complain to the city council over a few weeds, but as a builder who has been serving Tarrant, Denton, and Wise counties since 2001, he couldn’t help but see a parallel. To the average passerby, a messy highway is just an eyesore. To an expert ADU builder, a messy job site is a flashing red light.

At DFW ADU Pro, a division of Boomer Group Inc., we believe that the way a builder treats their trash says everything about how they’ll treat your home. If a contractor can’t be bothered to pick up a stray 2×4 or a soda can in your backyard, can you really trust them with the structural integrity of your foundation or the precision of your multigenerational home additions in Keller?

The "Unseen Standards" of a Clean Job Site

When you decide to build an accessory dwelling unit (ADU): whether it’s a guest house for your parents or a backyard cottage for a returning college grad: you are making a significant investment. You aren’t just buying a building; you’re buying a process.

A clean job site is a direct reflection of a builder’s craftsmanship. It’s about the "unseen standards" that separate a top-tier contractor from the rest of the pack. When our teams are on-site in Southlake or Keller, we maintain an immaculate workspace for several key reasons:

1. Safety and Respect: A cluttered site is a dangerous site. By keeping our projects tidy, we ensure the safety of our tradesmen and, more importantly, your family. We know your kids and pets are nearby; we treat your backyard like the sanctuary it is.
2. Attention to Detail: If a builder is disciplined enough to manage the small things: like daily debris removal: they are disciplined enough to manage the big things, like the exacting submittal process for city permits.
3. Efficiency: You can’t build a high-quality guest house if you’re constantly tripping over yesterday’s scrap heap. Organization leads to speed, and speed (done right) leads to a better experience for the homeowner.

Why Neighborly Pride Matters in North Texas

We aren't just building in these neighborhoods; we live here. We drive the same roads, shop at the same stores, and care about the same local aesthetics. When DFW ADU Pro takes on a project, we understand that we are temporarily guests in your neighborhood.

A messy construction site doesn't just annoy you; it affects your neighbors. We take pride in being the "quiet, clean neighbor" on the block. Our goal is for your neighbors to be impressed not just by the final backyard cottage, but by how professional the entire journey was.

As a PRO Construction affiliate: ranking in the top 1% of Texas contractors based on verified permit history: we handle the entire bureaucratic learning curve for you. From site feasibility to full permit management, we deal with the city so you don't have to. That authority comes from a place of discipline, starting with the very first shovel in the ground.

Built for Permanence: The DFW ADU Pro Standard

While some builders might offer "portable" solutions or temporary structures, we specialize in structural permanence. Our ADUs are built on solid slab foundations, designed to match the architectural soul of your primary residence.

We utilize premium materials that stand up to the North Texas heat and the test of time:

• Hardie Siding: We love the combination of board and batten with traditional horizontal lap siding. It creates a texture that feels both modern and timeless.
• Warm Earth Tones: Our palettes lean into tans, beiges, and sage greens: colors like Oklahoma Cream and Artisan Gold that feel right at home under a Texas sunset.
• Functional Porches: Every guest house builder in Keller, TX knows that a porch isn't a luxury: it’s a necessity. We design our porches with shade, ceiling fans, and enough room for a couple of rocking chairs, creating a functional outdoor living space.

Mid-Price Point, High-Value Solutions

We know that families are looking for practical, accessible solutions. Our 500-square-foot plans typically range between $125,000 and $150,000, offering a high-value alternative to traditional home additions or the soaring costs of assisted living facilities. For more details on budgeting, you can check out our 2026 ADU Cost Guide.

This isn't about intimidating luxury; it's about approachable craftsmanship. It’s about creating a space where Grandma can sit on the porch, rocking in her chair, and watch the kids play in the yard: all while having her own kitchen, her own bathroom, and her own independence just a few steps away.

Choosing a Partner Who Cares About the Details

When you see a DFW ADU Pro sign in a yard, you’ll notice the difference immediately. You won't see a "trashy median" situation. You’ll see a site that reflects the same level of care we put into the final coat of paint.

We’ve been building in Tarrant, Denton, and Wise counties since 2001, and we’ve learned that the best way to build a home is to build a relationship first. That relationship starts with respect: for your property, your time, and your family.

If you’re ready to explore how a detached ADU can change your family's life, let’s talk. We’ll bring the expertise, the "turnkey" convenience, and, most importantly, the broom.

Because at the end of the day, your ADU builder's job site says everything about the home they are building for you.

When you’ve lived in North Texas as long as we have: building across Tarrant, Denton, and Wise counties since 2001: you learn a few things about what makes a home work. It’s not just about square footage; it’s about the feeling of permanence, the relief of a shaded porch in July, and the peace of mind that comes from knowing your parents are safe and nearby.

At DFW ADU Pro, a division of Boomer Group Inc., we specialize in what we call the "Sweet Spot": 500-square-foot detached accessory dwelling units (ADUs) that bridge the gap between high-end luxury and practical affordability. For many families in Keller and Southlake, the goal is a high-value multigenerational living solution that stays within a $125,000 to $150,000 budget.

The secret to achieving that "estate-quality" look without the estate-sized price tag? It’s all in the siding and the porch. Today, we’re showcasing five designs that leverage the durability of Hardie siding in warm tones like Oklahoma Cream and Artisan Gold to create backyard cottages that don’t just "fit": they belong.

Why Hardie Siding is the North Texas Standard

Before we dive into the designs, let's talk shop. We exclusively use James Hardie fiber-cement siding because North Texas weather is unforgiving. Between the searing heat and the occasional hailstorm, vinyl or thin wood won't cut it.

We recommend a combination of board and batten (vertical) and horizontal lap siding. This mix creates architectural interest and depth, making a small 500 sq ft unit feel like a custom-built home. When finished in warm earth tones like tan, beige, and cream, these units reflect the Texas sun rather than absorbing it, helping with your energy efficiency from day one.

---

Design 1: The Keller Classic (Oklahoma Cream & Board and Batten)

The "Keller Classic" is our most popular request for homeowners who want their granny flat to feel like a natural extension of their main residence.

• Exterior: Full vertical board and batten siding in Oklahoma Cream.
• The Detail: We use Artisan Gold for the front door and window trim to provide a soft, welcoming contrast.
• The Porch: A 6-foot deep covered front porch with a high-efficiency ceiling fan.
• Why it works: The vertical lines of the board and batten draw the eye upward, making the 500 sq ft footprint feel much larger than it is.

Design 2: The Denton Duet (The Multi-Texture Masterpiece)

For families in Denton County who want a more modern farmhouse aesthetic, the "Denton Duet" utilizes a 60/40 split between siding styles.

• Exterior: Horizontal lap siding on the bottom three feet (the "wainscoting" look) with vertical board and batten above.
• The Palette: Warm gray and soft tan. This palette stays cool under the sun while offering a sophisticated, contemporary vibe.
• The Porch: Wrap-around style on one corner, providing two different angles for catching the evening breeze.
• The Foundation: Built on a permanent slab foundation, ensuring this unit is as sturdy as the primary home.

Design 3: The Southlake Suite (Artisan Gold Accents)

In Southlake, where architectural matching is often a requirement of HOAs, we focus on high-end finishes that mirror the main estate.

• Exterior: Traditional horizontal lap siding in a rich cream tone.
• The Detail: Use of Artisan Gold on the gable vents and porch columns.
• Functional Luxury: This design often features larger windows to bring in natural light, making the interior feel airy and open.
• Turnkey Management: As a top 1% ranking contractor in Texas, we handle the entire city submittal and inspection process, which is particularly helpful in municipalities with strict building codes.

Design 4: The Wise County Weekender (Maximum Shade)

Out in Wise County, space isn't usually the issue: the heat is. This design prioritizes the "Outdoor Living" aspect of an ADU.

• Exterior: Rough-sawn Hardie panels with wide-set battens for a rustic, hand-built feel.
• The Porch: An oversized front porch designed specifically for rocking chairs and potted plants. We often install dual fans here.
• Multigenerational Connection: This layout is perfect for a "grandma cottage," where the porch serves as a front-row seat to watch the grandkids play in the backyard.

Design 5: The Heritage Hybrid (Seamless Integration)

The "Heritage Hybrid" is designed for homeowners who have outgrown their space but refuse to leave their neighborhood.

• Exterior: A sophisticated mix of sage green lap siding with cream board and batten gables.
• The Hook: It features a "zero-step" entry for the porch, making it ideal for aging parents who may have mobility concerns in the future.
• The Value: At the $125,000–$150,000 price point, this design delivers a full kitchen, bedroom, and bathroom without compromising on the exterior "curb appeal" of your backyard.

The DFW ADU Pro Difference: Beyond the Siding

Choosing the right design is only half the battle. The other half is the "bureaucratic learning curve": something most homeowners (and many general contractors) aren't prepared for.

When you partner with DFW ADU Pro, a division of Boomer Group Inc., you aren't just hiring a builder; you’re hiring a permit authority. We’ve been building in North Texas for over two decades. We know the local soil, we know the local inspectors, and we know how to manage a project so that it stays on schedule and on budget.

Our turnkey solution includes:

1. Site Feasibility: Ensuring your backyard can support a detached unit with proper utility hookups.
2. Full Design: Selecting the Hardie siding combinations that match your existing home.
3. Permit Management: We handle the paperwork, the submittals, and the red tape.
4. Structural Permanence: All our ADUs are built on slab foundations: no pier-and-beam shortcuts here.

When you are looking to add an accessory dwelling unit (ADU) to your property in Southlake, Westlake, or Keller, you aren't just building a "shed with a bed." You are making a significant investment in your family’s future and your home’s long-term equity.

In North Texas, we have a specific architectural standard to uphold. Whether you call it a granny flat, a backyard cottage, or a guest house, the exterior needs to feel like a permanent extension of your primary residence: not an afterthought. At DFW ADU Pro, a division of Boomer Group Inc., we’ve found that the absolute "gold standard" for achieving this look is the strategic combination of James Hardie fiber-cement siding and natural stone masonry.

This combination offers the perfect balance: the approachable, warm charm of a cottage with the undeniable permanence of a Texas estate. Here is why the Hardie + Stone combo is the preferred choice for the most beautiful guest houses in our area.

The Art of Mixing Materials: Design Principles for North Texas

Building a high-value guest house requires more than just picking a color; it’s about texture and rhythm. For homeowners in Keller’s premium neighborhoods, a single-material exterior can often look flat or industrial.

We recommend a "tri-texture" approach:

1. Vertical Board and Batten: Using James Hardie board and batten in a warm tone like Oklahoma Cream adds height and a modern farmhouse flair.
2. Horizontal Lap Siding: Breaking up the vertical lines with traditional horizontal lap siding (often in a complementary shade like Artisan Gold) provides a classic residential feel.
3. Stone Masonry: Introducing stone at the base or on key architectural features grounds the building and signals high-end craftsmanship.

By mixing these materials, you create visual interest that guides the eye. This is particularly important for multigenerational home additions in Keller, where the ADU might sit close to the main house. The mix of materials allows us to "bridge the gap" between the existing architecture of your main home and the new structure.

Where Stone Accents Shine

As expert guest house builders in Keller, TX, we don't just "slap on" stone. We use it strategically to enhance the structural permanence of the unit. Here are the three most effective ways to incorporate stone:

1. The Foundation Wainscoting

By running a stone wainscot (typically 24 to 36 inches high) around the base of the ADU, we protect the lower portion of the Hardie siding from splash-back during Texas thunderstorms. More importantly, it creates a visual "weight" that makes the building look like it has been part of the landscape for decades.

2. Porch Column Bases

A front porch ADU is a staple of our North Texas designs. We love building deep, functional porches equipped with ceiling fans and rocking chairs. By using stone to wrap the base of the porch columns, we create a stately entrance that mirrors the luxury homes found throughout Southlake.

3. Chimney Features and Entry Gables

If your floor plan includes a fireplace or a vaulted entry, these are prime candidates for full-height stone masonry. It’s the ultimate way to elevate a "backyard cottage" into a "luxury guest suite."

Performance That Stands Up to the Texas Heat

Aesthetics are vital, but as a top 1% ranked contractor in Texas, DFW ADU Pro prioritizes durability. The North Texas climate is notoriously hard on exteriors. From the blistering summer sun to the sudden hailstorms we see in Tarrant and Denton counties, your ADU needs to be built to last.

• Hail Resistance: Both James Hardie siding and stone masonry offer superior impact resistance compared to vinyl or wood. This is a critical consideration for our service areas in Tarrant County.
• Fire Safety: Hardie siding is non-combustible. When paired with stone, you are creating a fire-resistant shell that provides peace of mind, especially when housing elderly parents.
• Low Maintenance: Unlike wood siding that rot or peels, this combo stays beautiful for years with minimal upkeep. The ColorPlus® Technology used in Hardie siding is specifically formulated to resist fading under the intense Texas UV rays.

The Multi-Generational Connection

The most common reason our clients seek out an adu builder is to bring the family closer together. We often build for "Grandma" or "Grandpa," providing them with a private, independent space that is only a few steps away from the grandkids.

When you choose a Hardie siding ADU with stone accents, you aren't just giving them a place to sleep; you’re giving them a home they can be proud of. Imagine Grandma sitting on a spacious adu with porch, shaded by a ceiling fan, watching the kids play on the lawn. The stone columns and warm cream siding create a backdrop that feels like a true family estate, fostering connection without sacrificing anyone's privacy.

Cost vs. Value: A Smart Investment

We position ourselves as a mid-price-point, high-value partner. While a basic 500 sq. ft. plan might start in the $125,000–$150,000 range, adding stone accents is one of the highest ROI (Return on Investment) upgrades you can make.

According to regional real estate data, stone veneer upgrades consistently recoup over 90% of their cost in terms of added property value. In high-equity markets like Westlake and Southlake, a guest house that matches the main home's masonry isn't just a luxury: it’s a requirement for maintaining the home’s resale value. You can learn more about North Texas pricing in our 2026 ADU Cost Guide.

Structural Permanence from the Ground Up

Luxury is only skin deep if the foundation isn't solid. Unlike "modular" or "portable" units, every DFW ADU Pro project is built on a engineered slab foundation. This ensures structural permanence and allows for the heavy weight of real stone masonry.

Image generated with AI

We handle the entire turnkey solution, from the initial site feasibility study to the final city inspections. Our deep local expertise in Tarrant, Denton, and Wise counties means we know the specific permit requirements for masonry and siding in your specific city. We manage the bureaucratic learning curve so you can focus on your family.

Conclusion: Build Something That Lasts

If you are ready to expand your living space, don't settle for a generic backyard building. Choose a design that combines the durability of James Hardie with the timeless beauty of Texas stone. Whether you need a place for aging parents or a premium guest suite, DFW ADU Pro is your expert partner in approachable craftsmanship.

A division of Boomer Group Inc.

As we move through 2026, the conversation around North Texas real estate has shifted from "Can I build it?" to "How does it impact my long-term costs?" At DFW ADU Pro, a division of Boomer Group Inc., we have seen a massive surge in homeowners in Keller, Southlake, and throughout Denton and Wise counties seeking to add an accessory dwelling unit (ADU). Whether it’s to provide a dignified space for aging parents or to create a primary suite expansion that keeps the family together, the benefits are clear.

However, a question we often hear during our initial site feasibility consultations is: "What is this going to do to my property taxes?"

It is a sophisticated question that deserves a sophisticated answer. In North Texas, the property tax landscape is nuanced, particularly with recent reappraisal plans and the unique way the State of Texas treats "new improvements." As your expert partner in residential construction, we’ve broken down everything you need to know about navigating property tax assessments for your new guest house in 2026.

1. The Valuation Reality: Market Value vs. Assessed Value

The first thing every homeowner must understand is the distinction between what your home is worth on the open market and what the county appraisal district (CAD) says it is worth for tax purposes.

When you hire a premier adu builder to construct a detached guest house, you are undeniably increasing the market value of your property. A permanent, slab-on-grade ADU finished with high-quality Hardie board and batten siding and a functional front porch is a highly sought-after asset in the DFW market.

However, your tax bill is calculated based on the Assessed Value. In North Texas, the appraisal districts (TAD in Tarrant, DCAD in Denton, and WCAD in Wise) look at your property as a whole. An ADU is treated as a "new improvement" to the existing parcel. The district will assign a value to that new structure based on its square footage, construction quality, and use.

2. The Tarrant County "Freeze" Myth

If you live in Tarrant County, you may have heard headlines about a "reappraisal freeze" for the 2025 and 2026 tax years. While it is true that the Tarrant Appraisal District (TAD) has moved to a plan that generally holds residential values at 2024 levels to provide stability, there is a major caveat: new construction and major additions are the exceptions.

For homeowners in Keller or Southlake, this means that while the "base" value of your main home might stay flat, the addition of an ADU will trigger a new appraisal for that specific improvement. You cannot "hide" a new 500 sq. ft. guest house behind the freeze. Because we handle full permit management, the county will be notified of the new square footage, and it will be added to the tax roll at its full market value.

3. Decoding the 10% Homestead Cap

One of the most powerful protections for Texas homeowners is the 10% Appraisal Cap. Under the Texas Property Tax Code, the assessed value of your residence homestead cannot increase by more than 10% per year.

Here is the catch for ADU owners: The 10% cap applies to the property you already had on the books. It does not limit the value of "new improvements" in the year they are first added to the tax roll.

For example, if your home in Denton County is valued at $500,000 and you add a $150,000 ADU:

• Your existing $500,000 valuation is protected by the 10% cap.
• The $150,000 for the ADU is added in full as new construction.
• Your new assessed value would be roughly $650,000 (plus any allowed 10% increase on the original $500,000).

In subsequent years, the entire $650,000 becomes the new base, and the 10% cap will then apply to the total. This is why working with guest house builders in Keller, TX who understand the cost-to-value ratio is critical. You want to ensure the value added is accurately reflected, not inflated by the district.

4. Estimating Your 2026 Tax Bill

While every municipality has different tax rates, we can use the effective tax rates for our primary service areas to create a ballpark estimate. As of 2026, here is how the math typically shakes out for a new detached ADU:

• Tarrant County (Keller, Southlake, Fort Worth): With an effective rate of approximately 1.47%, a $150,000 ADU adds roughly $2,205 to your annual tax bill.
• Denton County (Flower Mound, Lewisville): At roughly 1.43%, that same ADU adds approximately $2,145 per year.
• Wise County (Decatur, Rhome): Known for being more tax-friendly with a 1.06% effective rate, you’re looking at about $1,590 annually.

When you compare this to the cost of an assisted living facility: which can easily exceed $5,000 to $7,000 per month: the tax impact of housing an elderly parent in an in-law suite is a remarkably efficient financial move.

5. Why Turnkey Permitting Matters for Your Valuation

There is a temptation for some homeowners to try and build "under the radar" to avoid tax increases. As a Top 1% ranked contractor in Texas, we strongly advise against this. An unpermitted ADU is a liability: it cannot be legally insured, it creates massive headaches during a future home sale, and it often results in the county appraising the structure at a "highest and best use" rate that may exceed its actual value once they eventually discover it.

When DFW ADU Pro handles your project, we manage the entire city submittal and inspection process. We ensure the ADU is classified correctly. A detached guest house cost in Keller usually falls between $125,000 and $150,000 for a 500 sq. ft. plan. By having a clear, permitted record of the construction, you have the documentation needed to protest your taxes if the county overestimates the value of the improvement.

6. Protesting Your 2026 Assessment

If you finish your ADU in 2025, you will see it on your April 2026 Notice of Appraised Value. If the number looks high, you have the right to protest.

1. Deadline: Usually May 15, or 30 days after your notice is mailed.
2. Evidence: Use your construction contract from DFW ADU Pro to show the actual cost of the "new improvement."
3. Equity: Compare your ADU’s per-square-foot value to other multigenerational home additions in Keller.

We provide our clients with the necessary documentation to ensure their property is appraised fairly and accurately.

Conclusion: A High-Value Investment for North Texas Families

At the end of the day, property taxes are a sign of a growing investment. While the tax bill may increase slightly, the value of having your family close: and the massive increase in your property's equity: far outweighs the annual tax cost.

Our goal at DFW ADU Pro is to provide approachable craftsmanship that feels like a permanent, seamless extension of your home. We build with structural permanence (slab foundations) and timeless materials like Oklahoma Cream Hardie siding because we know these units aren't just "extra space": they are a legacy for your family.

Are you ready to explore the feasibility of an ADU on your property? Contact us today for a consultation. We’ll handle the permits, the construction, and the bureaucracy, so you can focus on what matters: the family waiting for that new front porch.

DFW ADU Pro
A division of Boomer Group Inc.

When you decide to add a detached accessory dwelling unit (ADU) to your property, you aren't just adding square footage; you are expanding your family’s legacy. Whether you are building an in-law suite for aging parents or a private guest house for returning adult children, the exterior design is the first statement your new home makes.

In the North Texas market: specifically across Tarrant, Denton, and Wise counties: we see two primary paths for exterior finishes. One path leads to the versatile, high-value Hardie siding cottage, and the other leads to the permanent, high-end masonry of brick and stone.

At DFW ADU Pro, a division of Boomer Group Inc., we specialize in helping homeowners navigate these choices. As a top 1% contractor in Texas with decades of local experience, we know that "curb appeal" isn't just about looks; it’s about architectural matching, local climate durability, and long-term property value.

The Mid-Price "Sweet Spot": The Hardie Siding Cottage ($125k–$150k)

For many families in Keller and the surrounding Tarrant County area, the James Hardie siding approach represents the "sweet spot" of ADU construction. It offers the perfect balance of aesthetic warmth, structural durability, and financial accessibility.

Oklahoma Cream and Artisan Gold

We’ve moved away from the dated "Oklahoma Crimson" tones and instead embraced a palette that reflects the modern North Texas landscape. Our most popular designs utilize Oklahoma Cream and Artisan Gold. By combining vertical board and batten siding with traditional horizontal lap siding, we create a textured, custom look that feels like a boutique cottage rather than a backyard "shed."

Designed for the Texas Heat

A North Texas ADU isn’t complete without a functional outdoor living space. Our Hardie cottages typically feature deep, covered front porches. We design these with the Texas summer in mind, including:

• High-efficiency ceiling fans to keep the air moving.
• Ample shade to protect from the afternoon sun.
• Plenty of space for rocking chairs and potted plants.

This is the quintessential setting for a grandmother to sit comfortably on her own porch, watching her grandchildren play in the shared backyard. It provides the independent living parents want with the "just a few steps away" connection families need.

The Luxury Investment: Brick & Stone Masonry

In high-value areas like Southlake and Westlake, an ADU needs to do more than just provide space: it needs to elevate the existing estate. For these properties, we recommend full brick and stone masonry.

Seamless Architectural Matching

In luxury neighborhoods, the goal is often "seamless integration." We source masonry that matches your primary residence’s brick and stone exactly. This ensures that the ADU looks like it was built at the same time as the main house, protecting your property’s appraisal value and overall estate aesthetic.

Long-Term Value Appreciation

While masonry comes with a higher initial price point, its ROI in luxury markets is substantial. A full-masonry ADU requires virtually zero exterior maintenance and offers superior thermal mass, which helps with energy efficiency during those record-breaking Texas heatwaves. If you are viewing your ADU as a 30-year investment in your property's equity, brick and stone are the gold standard.

Structural Permanence: Built on a Slab

Regardless of the siding you choose, every DFW ADU Pro project is built for permanence. Unlike "shed-style" units or portable buildings, our ADUs are built on engineered slab foundations.

This foundation is the bedrock of our "top 1%" ranking. We handle the entire city submittal and inspection process, ensuring that your ADU meets the same strict building codes as a primary residence. This structural integrity is what allows us to offer true turnkey solutions in Denton and Wise counties, giving you peace of mind that your family’s new home is safe and permanent.

Why the "Porch Life" Matters

At the heart of every ADU project we take on is a family story. We often see homeowners who have outgrown their space but love their neighborhood and don't want to move. By adding a detached suite, you gain a guest house that functions as a primary suite expansion or a dedicated home for a loved one.

The covered front porch is where that family connection happens. It’s the space for morning coffee, evening conversations, and neighborly check-ins. When we build with Hardie board or high-end brick, we aren't just selecting materials; we are building the backdrop for your family’s future memories.

Partner with the North Texas Experts

Choosing the right exterior is a consultative process. It requires an understanding of local zoning, neighborhood standards, and construction costs. Since 2001, we’ve been the trusted partner for homeowners in North Texas who want a stress-free building experience.

We handle the bureaucratic learning curve: the permits, the inspections, and the engineering: so you can focus on the design choices that matter most to your family. Whether you are looking for an approachable, $125k Hardie cottage or a luxury masonry guest house, we provide the craftsmanship and local expertise to bring your vision to life.

When you decide to add an accessory dwelling unit (ADU) to your property in Tarrant, Denton, or Wise County, you aren’t just building a "backyard cottage." You are making a smart, permanent investment in how your family lives now and how your property performs later. Whether it’s a dedicated in-law suite for your parents to age in place or a private space for a grown child returning home, the exterior of that structure signals quality, durability, and long-term value.

As an experienced guest house builder serving North Texas since 2001, we’ve seen the same question come across our desks hundreds of times: "Should I go with brick to match my main house, or is Hardie siding the better move for my guest house?"

The answer isn't a simple "yes" or "no." It’s about balancing aesthetic appeal, maintenance, architectural matching, and your budget. Let’s break down the "Chief Closer" perspective on the two most popular choices for North Texas homeowners.

The North Texas Context: Why Materials Matter

In towns like Keller and Southlake, your home is likely your biggest asset. Adding a detached guest house shouldn't just provide square footage; it should enhance your property’s appraisal value. North Texas presents unique challenges: foundation-shifting clay soil, blistering summer heat, and the occasional "Texas-sized" hail storm.

At DFW ADU Pro, a division of Boomer Group Inc., we prioritize structural permanence. Every unit we build starts with a professionally engineered slab foundation. But once the foundation is poured, the "skin" of the building determines its character.

Hardie Siding: The Versatile Modern Standard

Fiber-cement siding, specifically James Hardie® products, has become the gold standard for a hardie siding adu in the DFW area.

Why Homeowners Love It:

1. Aesthetic Flexibility: Hardie allows for the popular board and batten guest house look. This vertical texture, often paired with horizontal lap siding, creates a "modern farmhouse" vibe that feels fresh yet established.
2. Architectural Matching: For many families in Keller, Southlake, and surrounding communities, the goal is not to make the ADU look like an afterthought. Hardie gives us the flexibility to closely match trim profiles, color palettes, and siding patterns so the new structure feels like it was always part of the property.
3. Color Palette: We specialize in warm earth tones: tans, beiges, creams, and sage greens. Hardie holds paint exceptionally well, which helps us create a seamless architectural match to your primary residence.
4. Resistance: It is non-combustible and resistant to rot and wood-boring insects. For a 500 sq ft guest house, this provides a massive upgrade over traditional wood siding.

Brick: The Traditional Powerhouse

Many North Texas luxury estates are 100% brick. If your main home is a classic brick manor, you might feel compelled to match it exactly.

The Chief Closer's Take on Brick:

Brick offers incredible thermal mass. In the middle of a 105-degree July day in Keller, brick stays cooler longer, taking the pressure off your HVAC system. It is the ultimate "set it and forget it" material. No repainting every 10 years; just the occasional power wash.

However, brick is heavy. It requires a more robust foundation ledge and significantly more labor-intensive masonry work. In the DFW market, where masons are abundant, brick is more affordable than in other parts of the country, but it still typically carries a premium over siding.

---

The Cost Reality: Finding the Sweet Spot

We position ourselves as a "mid-price-point, high-value" partner. For a standard 500 sq ft guest house cost, most families should expect a realistic turnkey investment in the $125,000 to $150,000 range, depending on exterior material choices, finish selections, and site conditions.

• Hardie Siding Option: Generally keeps you in the most efficient part of that $125k-$150k range, allowing you to invest more in interior finishes like vaulted ceilings or premium kitchenettes.
• Full Brick Option: Can push the budget toward the top of the range or beyond, depending on the brick’s rarity and the complexity of the masonry.
• The Hybrid Solution: A very popular choice among our clients is to use a brick "wainscot" (the bottom 3-4 feet) with board and batten Hardie siding above. This provides the durability of brick where it counts most, with the style of siding and strong architectural matching to the main home.

Functional Features: The Texas Front Porch

Regardless of whether you choose brick or Hardie, a front porch ADU is a non-negotiable for North Texas living. We design our porches as functional living spaces. Imagine a multigenerational home addition where Grandma can sit in a rocking chair under a ceiling fan, watching the grandkids play in the backyard.

Our porches are designed for the Texas heat, featuring:

• Generous shade cover.
• High-efficiency ceiling fans.
• Seamless architectural matching so the porch feels like a natural extension of the yard.

The Turnkey Advantage

The bureaucratic learning curve for guest house builders in Keller, TX, or Southlake can be steep. From city submittals to final inspections, the process is full of hurdles.

As a top 1% ranking contractor in Texas, DFW ADU Pro handles the entire "red tape" process. We manage the site feasibility, the design, and the full permit management. You don't have to worry about whether your siding choice meets local fire codes or if your brick ledge is deep enough: that’s our job.

The Verdict: Which Is Better?

If you want a hardie siding adu that feels current, matches the main home with more design flexibility, and keeps your initial investment in the practical $125,000-$150,000 sweet spot, Hardie siding is your winner.

If you are looking for maximum thermal efficiency, low-maintenance longevity, and a near-exact match for a traditional brick estate, then brick is worth the extra investment.

Either way, the real key is working with a guest house builder that understands structural permanence, finish coordination, and city requirements for a lasting in-law suite or family guest house. Ready to see which option fits your backyard? At DFW ADU Pro, we don't just build structures; we deliver turnkey solutions built to belong.

At DFW ADU Pro, a division of Boomer Group Inc., we believe that building a home is about more than just square footage and slab foundations. It’s about the people who live inside them and the communities they’ve spent their lives building. Since 2001, our team has been working in the trenches of Tarrant, Denton, and Wise counties, helping North Texas families expand their horizons, literally.

But we’ve always known that our success is built on the shoulders of the men and women who serve our neighborhoods. Whether you’ve worn the uniform of our country, spent your career protecting our streets as a police officer, or spent your retirement years as the cornerstone of your family, we believe you deserve a partner who values your contribution.

That’s why we are officially announcing our specialized discount programs for Seniors, Veterans, and First Responders (Police, Fire, and EMS).

If you are looking for an accessory dwelling unit to help an aging parent move closer to home, or if you’re a retired veteran looking to simplify your life with a high-value backyard cottage, we’re here to make that happen with the respect and craftsmanship you’ve earned.

Why We Focus on Those Who Serve

As a locally owned ADU builder, we don’t answer to out-of-state shareholders. We answer to the residents of Keller, Southlake, and the surrounding North Texas communities. We’ve seen firsthand how an in-law suite can transform a family's dynamic, providing "Custom Comfort for the Ones You Love" while keeping everyone connected.

Our "Chief Closer" philosophy is simple: we provide sophisticated, authoritative guidance through the complex world of residential construction, but we do it with a neighborly handshake. We handle the bureaucracy so you don't have to. For our veterans and first responders, who have spent their careers navigating high-stress environments, the last thing they need is a headache from city hall. That’s why our turnkey solutions include full permit management and site feasibility from day one.

Multigenerational Living: Honoring Our Seniors

The "granny flat" isn't just a trend; it's a solution to a real North Texas challenge. Many families in Tarrant, Dallas and Denton counties are finding themselves in the "sandwich generation": caring for aging parents while raising children.

A detached ADU provides the perfect balance:

• Independent Living: Seniors maintain their autonomy with a private kitchen, living area, and bedroom.
• Safety & Accessibility: Our designs focus on aging-in-place features, from walk-in showers to accessible layouts.
• Permanent Connection: Grandma can be on the front porch watching the grandkids play in the yard, all while having her own space to retreat to at the end of the day.

For seniors, these units represent more than just an addition; they are a way to stay in the neighborhood they love without the maintenance of a 3,000-square-foot estate.

The Veteran and First Responder Advantage

If you are active-duty military, a veteran, or a first responder (Police, Fire, EMS), your service to North Texas hasn't gone unnoticed. We know the sacrifices made by those who keep our communities safe.

Building a guest house in Keller TX or a secondary suite in Wise County shouldn't be an uphill battle. Our discounts are designed to make high-quality, permanent construction more accessible. While some "tiny home" builders offer temporary solutions on wheels, we focus on structural permanence.

Every project we touch is built on a slab foundation with the same rigor as a primary residence. When you invest in a DFW ADU Pro unit, you are investing in a permanent asset that adds tangible value to your property and provides a rock-solid home for your family.

Craftsmanship That Matches Your Home

We don't build "boxes in the backyard." Our design team specializes in architectural matching, ensuring your new ADU looks like it was always meant to be there.

Our standard features are curated for the North Texas climate and aesthetic:

• Hardie Siding: We use a combination of board and batten with horizontal lap siding for that timeless "modern farmhouse" or "craftsman heritage" look.
• Warm Palette: We favor earth tones like tan, beige, warm gray, and sage green: colors that reflect the "Texas-friendly" spirit.
• Texas Porches: Our front porches are functional living spaces. We include ceiling fans to fight the summer heat and plenty of room for rocking chairs.
• High Value: We position our projects at the "mid-price-point, high-value" tier. A standard 500 sq. ft. plan typically ranges between $125,000 and $150,000, offering a premium experience without the "intimidating luxury" price tag.

Local Expertise: We Know Tarrant, Denton, and Wise Counties

Building in North Texas requires more than just a hammer and nails; it requires a deep understanding of local municipal codes. From the specific setbacks in Southlake to the permitting quirks in Keller, our history as a PRO Construction affiliate (ranked in the top 1% of Texas contractors) means we have the permit history to back up our claims.

We take the "turnkey" promise seriously. Our process includes:

1. Site Feasibility: Can you build? We’ll find out.

Serving Tarrant, Dallas, Denton, Wise Counties and North Texas and Southern Oklahoma areas.

When you decide to add an accessory dwelling unit (ADU) to your property in Keller, Southlake, or anywhere across Tarrant, Denton, and Wise counties, you aren’t just building a "shed" or a temporary cabin. You are creating a permanent extension of your home: a place where your parents might live out their golden years or where your adult children can find independence while staying close to family.

One of the most frequent questions we hear at DFW ADU Pro, a division of Boomer Group Inc., is about the exterior: "Should we use James Hardie siding or go with full brick?"

In North Texas, this isn't just an aesthetic choice. It’s a decision that impacts your property value, your long-term maintenance, and, most importantly, your budget. As a top 1% ranked Texas contractor, we’ve seen how both materials perform under our unique climate. Here is the consultative breakdown of how to choose the right shell for your backyard cottage.

The Case for Hardie Siding: Performance and Style

For most North Texas families looking for a high-value, mid-priced solution ($125,000–$150,000 for a 500 sq ft plan), James Hardie fiber-cement siding is often the superior choice.

At DFW ADU Pro, we specialize in "architectural matching." This means we don't want your ADU to look like an afterthought. By using a combination of Hardie board and batten for vertical texture and horizontal lap siding for traditional lines, we can create a sophisticated, modern farmhouse or craftsman look that feels intentional and upscale.

Why Hardie Wins in the Backyard:

1. Texas-Weather Tough: Hardie siding is specifically engineered for our climate. It’s non-combustible (a major plus for insurance and safety) and resists rot and termites. Whether it's a 105-degree August day or a sudden North Texas hail storm, this material holds its own.
2. Color Flexibility: We focus on warm trend colors: tans, beiges, warm grays, and creams: that reflect a "Texas-friendly" vibe. Hardie’s ColorPlus® technology ensures the finish lasts for years without the constant need for repainting.
3. Cost Efficiency: Hardie allows us to stay within that accessible $125k–$150k price point while still delivering a luxury feel. It is significantly lighter than brick, which means less stress on the soil and more flexibility in design.

The Appeal of Brick: Permanence and Prestige

While Hardie siding is incredibly popular, many homeowners in established Tarrant County neighborhoods prefer brick to achieve a seamless match with their primary residence.

Brick is the "set-and-forget" material of the residential world. It offers unparalleled thermal mass: helping keep the interior cool during our scorching summers: and provides a level of sound dampening that is excellent for high-density areas.

Image generated with AI

When Should You Choose Brick?

• HOA Requirements: Some communities in Southlake or Keller may have strict "masonry requirements" that mandate at least 75% or even 100% brick or stone.
• Longevity: While Hardie lasts for decades, brick is measured in centuries. If you view this ADU as a 100-year asset, brick is the way to go.
• Property Value: In certain high-end neighborhoods, a full-brick ADU may provide a slightly higher boost to your total property appraisal compared to siding.

However, be prepared for the investment. Brick requires more labor-intensive masonry work and a more robust foundation structure, which often pushes the cost of a 500 sq ft guest house beyond the $150,000 mark.

Structural Permanence: It Starts with the Slab

Regardless of whether you choose Hardie or brick, the most critical element of your ADU is the foundation. At DFW ADU Pro, we don't believe in "portable" buildings or temporary skids. Every project we undertake: from a simple granny flat to a complex primary suite expansion: is built on a engineered slab foundation.

Image from DFW ADU Pro marketing library

This structural permanence ensures your investment won't shift, warp, or settle poorly over time. When we handle your site feasibility and design, we take the North Texas clay soil into account to ensure your ADU remains a rock-solid part of your estate.

The "Grandma Approved" Front Porch

One detail we never compromise on: regardless of the siding material: is the front porch. In Texas, a porch isn't just an entry; it's a functional living space.

We design our backyard cottages with covered porches featuring:

• High-output ceiling fans to beat the Texas heat.
• Deep overhangs for maximum shade.
• Space for rocking chairs where a grandma can sit and watch her grandchildren play in the yard.

This "Texas-friendly" approach creates a bridge between the ADU and the main home, fostering the multigenerational connection that is at the heart of why we build.

Turnkey Solutions and Permit Management

Choosing between Hardie and brick is a big decision, but it’s only one of a hundred choices you'll have to make. This is why homeowners choose DFW ADU Pro. We offer full permit management and complete turnkey solutions.

We handle the city submittals in Keller, Southlake, and beyond. We manage the inspections, the plumbing, the electrical, and the architectural matching. You don't have to learn the bureaucratic learning curve of the local planning department: we’ve been doing this since 2001.

The Final Verdict: Which Is Better?

• Choose Hardie Siding if you want the best balance of price ($125k–$150k), durability, and modern style. It’s the smart choice for most families who need a functional, beautiful in-law suite.
• Choose Brick if your neighborhood requires it, or if you want the absolute highest tier of longevity and are prepared for the higher price point.

At DFW ADU Pro, we are your expert partners in navigating these choices. Whether you are in Tarrant, Denton, or Wise county, we are here to help you build a space that honors your family and enhances your property.

If you are looking to build a guest house builder in Tarrant, Denton, or Wise County, you aren't just looking for extra square footage. You are looking for a permanent extension of your family’s legacy. Whether you’re housing aging parents in a comfortable in-law suite or giving a grown child their first taste of independence in a backyard cottage, the exterior finish of that home matters.

At DFW ADU Pro, a division of Boomer Group Inc., we believe a $150,000 investment should look like it belongs. It shouldn't look like a "shed" dropped in a yard; it should look like it was built alongside your primary residence twenty years ago. That starts with choosing the right James Hardie siding.

In North Texas, the "Modern Farmhouse" trend is shifting. We are moving away from stark, cold whites and toward a palette of warm neutrals that reflect our Texas landscape and handle our 100-degree summers with grace.

Why Hardie Siding is the Gold Standard for Texas ADUs

When we talk about an accessory dwelling unit (ADU), we talk about structural permanence. Unlike portable buildings, our units are built on engineered slab foundations. To match that internal strength, the exterior needs to be equally resilient.

James Hardie fiber cement siding is our primary recommendation for three reasons:

1. Fire Resistance: Crucial for detached structures in suburban North Texas.
2. Heat Performance: Hardie doesn't warp like vinyl or rot like wood under the relentless Texas sun.
3. ColorPlus® Technology: The finish is baked on, meaning your granny flat won't need a repaint every five years.

For a 500 sq ft guest house cost between $125k and $150k, Hardie provides the highest ROI and the most professional finish.

The Warm-Tone Palette: Comparing Your Options

Choosing a color is more than an aesthetic choice; it’s about thermal efficiency and neighborhood harmony. Here is how the most popular warm tones for Keller and Southlake compare:

1. Navajo Beige: The Neighborhood Classic

Navajo Beige is the "Chief Closer" of the color world. It is authoritative, warm, and universally accepted by HOAs in Tarrant County. It pairs perfectly with the red and brown brick common in Tarrant County homes. It hides North Texas dust exceptionally well and maintains a "clean" look year-round.

2. Cobble Stone: The Sophisticated Greige

If you want something slightly more modern but still warm, Cobble Stone is a "greige" (gray-beige) that offers incredible flexibility. It works beautifully with Oklahoma Cream limestone accents. It provides a sophisticated backdrop for a front porch ADU featuring dark wood rockers and black ceiling fans.

3. Monterey Taupe: Depth and Character

For homeowners who want their detached guest house to feel substantial, Monterey Taupe offers a deeper, more grounded hue. It’s a favorite for multigenerational home additions in Keller because it contrasts sharply with crisp white trim, giving the building an "architectural" feel that justifies a $150k price point.

4. Mountain Sage: The Natural Choice

Sage green is the breakout star of 2026. A hardie siding ADU in Mountain Sage feels like a retreat. It blends into the backyard landscape, making the structure feel less like a building and more like a part of the garden. Pair it with a tan trim to keep the "warmth" front and center.

Texture Play: Board and Batten vs. Horizontal Lap

A common mistake we see with amateur builders is using a single siding profile for the entire building. This makes a 500 sq ft unit look small. To achieve that mid price ADU 125k 150k value, you need texture.

We recommend a combination:

• Horizontal Lap Siding: Use this for the main body of the house. It creates a timeless, traditional look that elongates the structure.
• Board and Batten: Use this vertical style on gables, entryways, or "bump-outs." A board and batten guest house detail adds height and a custom, artisan feel.

By mixing these textures, we ensure your adu with porch texas doesn't just meet code: it exceeds expectations.

The "Grandma-Approved" Front Porch

In North Texas, a porch isn't a luxury; it's a functional living requirement. When we design a 500 sq ft guest house, we often emphasize a deep, shaded front porch.

Why? Because it facilitates connection. We love seeing our clients' homes where grandma can sit on her porch in a rocking chair, shielded from the sun by a high-efficiency ceiling fan, while watching the grandkids play in the main yard. This "transitional space" is what turns a house into a home.

When choosing siding colors, we often use a lighter "cream" or "Artisan Gold" accent under the porch roof to reflect light into the windows, keeping the interior of the ADU bright and airy.

Managing the Investment: The $150k Build

You may see "cheap" options online for $60k or $80k. At DFW ADU Pro, we don't build those. We build structural permanence.

For a detached guest house cost in Keller, $125,000 to $150,000 covers:

• Full permit management (handling the city submittals you don't want to touch).
• Engineered slab-on-grade foundations.
• James Hardie siding with custom texture mixing.
• Full HVAC, plumbing, and electrical integrated into your existing site.
• Seamless architectural matching.

We handle the bureaucratic learning curve so you can focus on your family. Being a top 1% ranked Texas contractor means we don't cut corners on the things you can't see: like the framing and the foundation: so the things you can see (like that beautiful Navajo Beige siding) stay perfect for decades.
