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:
- Vaulted Ceilings & Timber Beams: Creating vertical volume makes a smaller footprint feel expansive.
- Chef-Inspired Kitchenettes: We utilize quartz countertops, custom-built cabinetry, and high-efficiency stainless steel appliances.
- Spa-Like Bathrooms: Walk-in showers with designer tile and premium fixtures provide the comfort your guests or parents deserve.
- 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."
