Building an ADU in Southlake isn’t like building one anywhere else in Texas. Deed restrictions, the Architectural Control Committee, and estate-sized lots with custom brick and stone homes all shape how a casita or guest suite gets designed, permitted, and built here. We work across Southlake neighborhoods including Timarron, Carillon, and Estes Park, and we coordinate directly with HOAs and the ACC so your project doesn’t stall in review. If you’re planning a detached ADU, pool house, or luxury guest suite, call Benson ADU Fort Worth at (682) 204-9686 for a written price before anything gets ordered.
Why Benson ADU Fort Worth Is Southlake’s Preferred ADU Builders Company
We’re known around Southlake for doing one thing that most builders won’t: putting a fixed price in writing before the long-lead materials get ordered. On a high-end casita with custom cabinetry, specialty glass, and stone veneer matching the main house, that early number is the difference between a smooth build and a budget that drifts for eight months. Homeowners in Timarron and Carillon call us because they’ve heard from neighbors that our written quote is what we actually build to.
Troy Eastman leads our team, and he’s built a reputation for walking Southlake clients through the ACC submission process rather than treating it as an afterthought. We don’t wait until the plans are done to figure out what the HOA will approve. We submit elevations, material samples, and landscape plans early. That local knowledge is why ADU Builders in Southlake projects with our team tend to clear review faster than homeowners expect.
Every Southlake project gets background-checked, uniformed crews, a live person on the phone around the clock, and a 365-Day Done Right Promise in writing. You’ll know who’s on your property and what they’re doing every day.
ADU Plans in Southlake
ADU Plans in Southlake are where the project is won or lost. A proper plan set for a Southlake ADU includes architectural drawings, elevations, material specifications, and landscape integration, all formatted to satisfy the ACC review in communities like Estes Park and Timarron. Most Southlake homeowners need this service before they can even get a building permit, and it typically runs $4,500 to $9,800 depending on the complexity of the casita and the level of interior detailing.
ACC-Ready Drawing Sets
We prepare drawing sets that anticipate what Southlake’s Architectural Control Committee will flag. Stone or brick veneer notes matching the main house, window schedules, roof pitch, and site placement all go in from the start. You don’t resubmit three times because a reviewer wants a different material callout.
Fixed-Price Plan Coordination
Once the plans are locked, we issue a written fixed price for the build. That number doesn’t shift because a millwork shop quotes a longer lead time later. The contract accounts for it up front.
ADU Contractor in Southlake
An ADU Contractor in Southlake handles the full build from foundation to finish, including ACC coordination, utility connections, and interior fit-out. This is the service Southlake homeowners choose when they want one accountable team rather than juggling separate designers, engineers, and subs. A custom detached ADU in Southlake typically runs $180,000 to $310,000 for a fully appointed casita with a kitchenette and bath, while a prefab installation on a prepared site can start around $95,000.
Custom Casita Construction
We build guest suites and pool houses that match the estate character of Southlake homes. That means brick or stone veneers, high-efficiency HVAC sized for southern exposure, and storm-rated glazing that North Texas hail won’t turn into a call-back.
Prefab and Modular Installation
For homeowners who want a faster path, we’re authorized builders for prefab brands including Boxabl, Mighty Buildings, and Tuff Shed. Prefab still goes through Southlake’s ACC process, and we handle that paperwork the same way we would on a custom build.
Trusted Brands We Service in Southlake
Southlake homeowners tend to research materials before they commit, so we build with names they can verify independently. We’re authorized to work with Boxabl, Mighty Buildings, and Tuff Shed, and we specify James Hardie cladding where the main house uses fiber cement. We keep local parts and material accounts with suppliers that serve the Southlake, Colleyville, and Keller corridor, so replacement trim, panels, and hardware don’t sit on a truck waiting for a Dallas warehouse run. If you’re comparing prefab options side by side, we’ll walk you through the ACC implications of each before you choose.
Common ADU Builders Problems We See in Southlake Homes
- ACC rejection on materials. A builder specs a fiber cement panel that doesn’t match the main house’s stone or brick, and the Architectural Control Committee sends it back. We match cladding and roof materials to the primary residence before submission, so review doesn’t loop.
- HVAC sizing fights the design. Southlake’s hot, humid summers punish an undersized unit, especially when an architect puts in a south-facing window wall. We coordinate duct layout with glass placement so the 3-ton unit isn’t blowing against solar gain all afternoon.
- Long-lead items kill the schedule. Custom steel doors, specialty glass, and millwork cabinetry can run 14 to 20 weeks from order. On a Timarron casita we’re finishing now, the cabinetry lead time ran 14 weeks from a Fort Worth millwork shop, so we locked the cabinet order before demolition and wrote the fixed contract before those orders went out.
- HOA fines for unfinished structures. When a builder assumes labor drives the timeline and discover backordered glass, the structure sits unfinished, and some Southlake HOAs levy fines for that. Our written schedule treats lead times as the real calendar, not framing days.

FAQs About ADU Builders in Southlake
How does Southlake’s Architectural Control Committee review affect my ADU timeline?
Southlake’s ACC review typically adds four to eight weeks to a project start, depending on the community. In master-planned neighborhoods like Timarron, Carillon, and Estes Park, you must submit elevations, material samples, and landscape plans before any construction begins. That’s longer than neighboring Keller or Grapevine, where deed restrictions are lighter. We build that review window into the written schedule so your move-in date doesn’t slip. Call (682) 204-9686 and we’ll map out your specific HOA process.
Why do Southlake ADU builders order custom cabinetry before construction starts?
Because the lead time runs 14 weeks or more from local millwork shops. On a recent Timarron casita, our crew locked the cabinet order before demolition so the building wasn’t waiting on a saw table in Fort Worth. If you order cabinets after framing starts, you’re adding three to four months to your finish date. That’s why our fixed-price contracts account for long-lead orders up front.
Can I build a pool house ADU with a bathroom and kitchenette under Southlake zoning?
Yes, and it’s one of the most common projects we build in Southlake. A detached pool house with a full bath and kitchenette is allowed as an ADU if it meets setback and lot coverage rules, and if the ACC approves the exterior design. The casita must match the main house’s architectural character, including cladding and roofline. Call (682) 204-9686 to get a written price for the exact plan you’re considering.
What is the biggest schedule risk for a high-end ADU in Southlake?
Custom steel doors, specialty glass, and long-lead millwork are the biggest risks. Standard framing goes quickly once the foundation is in. What stalls a Southlake ADU is a 20-week backorder on a custom door or a glass package that doesn’t arrive when the schedule assumed. We write contracts with lead times as the driver, so the calendar reflects reality before you sign. Want the full breakdown? Call (682) 204-9686.
Do Southlake HOAs require the ADU to be hidden from the street?
Many Southlake communities, especially those with strict deed restrictions like Estes Park and Timarron, require the ADU to sit behind the main structure or be screened from street view. The ACC reviews site placement before approval, and some HOAs require landscape screening or a specific setback from the rear property line. We submit siting plans with your elevations so the review isn’t a surprise. Call (682) 204-9686 and we’ll check your specific deed restrictions before you commit to a design.
