Why Benson ADU Fort Worth Is Southlake’s Preferred Room Addition Contractor Company
Southlake homeowners call us because we speak the language of architectural review boards, not just building codes. Troy Eastman and our Room Addition Contractor team have worked projects in Timber Lake, Estes Park, and along Southlake Boulevard where the HOA’s design standards dictated everything from window mullion profiles to the exact mortar color on a stone veneer addition. That’s the work most contractors trip over. We don’t, because we handle the review submission, the revision cycles, and the resubmission as part of the written scope.
We’re part of the Relay Home Co. family, established 2006. Every technician who steps onto a Southlake property is background-checked and in uniform, and a live person answers the phone around the clock. You won’t get a voicemail loop when you call to ask why the casita’s glass hasn’t arrived. You’ll get a straight answer and a photo of the tracking update if that’s what the moment calls for.
ADU Conversion in Southlake

ADU Conversion in Southlake is rarely a simple garage flip; it’s more often a detached or attached guest suite built to match the architectural language of a large custom home, and that changes everything about how the job gets priced and scheduled. Expect $190,000 to $350,000 for a fully appointed Southlake casita with a kitchenette, full bath, and separate climate control, depending on whether you select a prefab panel system from Dvele or Plant Prefab or go fully site-built with custom millwork. The HOA submission happens first, before materials are ordered, because what the board approves dictates what we buy.
Prefab Panel Casitas
When the board’s aesthetic demands real stone and a matched roofline, a prefab module can still be the smart move. We integrate the factory-built core with site-finished veneers and trim so the addition reads as original. Lead times on Dvele and Plant Prefab panels run 18 to 26 weeks in this market, so we order the moment the architectural review clears.
Site-Built Guest Suites
For homeowners who want fully custom interiors, a site-built guest suite gives us control over every finish inside the envelope. That also means the millwork schedule drives the whole project. We source cabinetry and trim from our own shop to avoid the 30% price swings that outside vendors can introduce mid-project, and we lock that pricing in writing before the first cut.
Sunroom Builders in Southlake
Sunroom Builders in Southlake work under a climate that punishes cheap glass and cheap framing within three summers. A proper Southlake sunroom is a conditioned four-season room with insulated glazing, storm-rated ties, and an HVAC load calculation done for the exact orientation of the addition. Budget $85,000 to $160,000 for a well-built sunroom addition here, with architectural glass packages from brands like Dvele pushing the upper end when floor-to-ceiling glazing is specified.
Shaded Outdoor Living Rooms
North Texas sun makes unshaded glass rooms unusable from June through September. We design sunrooms with integrated roof overhangs, motorized solar shades, and low-E glazing tuned to the southern and western exposures common on Southlake’s larger lots. The goal is a room that’s actually comfortable in August without running three portable AC units.
Storm-Ready Glazing
Severe storm cycles are part of living in this part of Texas. Our sunroom builds use impact-rated glazing when the budget allows and always use hurricane-rated clips at the roof-to-wall connection. It’s not code minimum in every Southlake neighborhood, but it’s the difference between a room that lasts 30 years and one that fails at year five.
Trusted Brands We Service in Southlake
Southlake homeowners tend to research products before they research contractors, which is exactly why we build with brands you can verify yourself. We’re authorized to source and integrate Dvele, Mighty Buildings, and Boxabl systems, and we keep familiarity with James Hardie cladding details that pass Southlake’s architectural review standards. When you call us about a specific brand, we can tell you what lead times actually look like, which systems fit Southlake’s masonry-matching requirements best, and what the real installed cost will be. No take-it-or-leave-it product lines, just options with honest timelines attached.
Common Room Addition Contractor Problems We See in Southlake Homes
- HOA review stalls that kill schedules: Southlake architectural boards often meet once a month, and a deferred application resets the clock another 30 days. We front-load the submission with the drawings, finish samples, and material specs the board wants, because a third revision is where most homeowners give up.
- Millwork that warps in the first humid summer: Southlake’s humidity cycle is hard on wood unless it’s properly kiln-dried, acclimated, and sealed before install. Our shop preps trim and cabinetry for the specific moisture range of an attached or conditioned addition, not a coastal spec sheet.
- Glass that fogs within a year: Inexpensive insulated glass units fail fast in the heat-and-storm cycles here. We specify architectural-grade IGU construction with proper drainage and flashing, especially on sunroom and casita glazing that takes direct afternoon sun.
- Quotes that don’t survive the long-lead order: Custom cabinetry and specialty glass from Dvele or Plant Prefab can swing 20 to 30 percent between a verbal estimate and the actual purchase order. Our written price binds that number before we order, and you see the line items before you sign.
Pricing for Room Addition Contractor in Southlake, TX
A typical ground-up room addition in Southlake runs $180,000 to $320,000, with casitas and ADU conversions landing between $190,000 and $380,000 when custom millwork, architectural glass, and full HVAC are included. Sunrooms fall in the $85,000 to $160,000 range depending on glazing specification. What moves the number most in Southlake is the masonry-matching requirement: veneering a new addition in real stone to match an estate home costs more than fiber cement lap siding, and the HOA rarely lets you choose the cheaper option. We give every homeowner a written, line-item price before any work starts, and that price holds because we lock material costs before ordering.

FAQs About Room Addition Contractor in Southlake

In Southlake, HOA architectural review typically takes 30 to 90 days from submission to approval, depending on the board’s meeting calendar and whether revisions are requested. Most Southlake boards meet monthly, so a single round of requested changes can push the timeline by another 30 days. We prepare the initial submission to anticipate the common objections, which is why our Southlake clients usually clear review in one or two cycles, but the honest answer is that the board sets the pace. Call (682) 204-9686 and we’ll walk your specific HOA’s requirements before you spend a dollar on drawings.
In the vast majority of Southlake neighborhoods with deed restrictions, the answer is yes: new additions must match the main house’s masonry veneer in material, color, and coursing pattern, and the roofline must align with the existing architecture. This is not a city code requirement across most of Texas, but Southlake’s HOA design standards typically mandate it. Our team sources matching veneer and documents the match for the board before submission, because failing this review point is the most common single reason Southlake additions get deferred. Get a free estimate at (682) 204-9686 to discuss your specific home’s finish materials.
Yes, a prefab ADU from Dvele or Plant Prefab can pass Southlake’s architectural review when the exterior finishes are specified and installed to match the main house, but the factory module alone rarely passes on the first submittal. The board reviews the built result, not just the product brochure, which means the cladding, roof form, window trim, and foundation treatment all need to align with the neighborhood’s design standards. We’ve done this in Southlake’s Estes Park neighborhood, where a Dvele module was integrated into a 2000s brick estate with a natural stone veneer addition and James Hardie siding on secondary elevations to pass review. The prefab path works here, but it needs a contractor who knows what the board will actually scrutinize.
The biggest schedule delays on high-end Southlake room additions are HOA architectural review cycles and long-lead material orders for custom millwork, architectural glass, and specialty cladding, not labor availability. A single deferral from a monthly board meeting adds 30 days, and custom cabinetry from certain vendors can take 18 to 22 weeks once ordered. We sequence the submittal, the material purchase, and the permit filing so those timelines overlap rather than stack, but the truthful answer is that lead times set the calendar on this tier of work. For a realistic schedule on your project, call (682) 204-9686.
Yes, a Southlake casita or pool house addition should get its own dedicated HVAC system, sized for the specific orientation, glazing, and occupancy of the new space rather than sharing load with the main house. Southlake’s humid summers punish undersized or shared ductwork, and a fully conditioned casita with a kitchenette and bath needs independent climate control to hold temperature and manage humidity properly. We include a Manual J load calculation in every written proposal so the system matches the actual addition, not a guess. Call (682) 204-9686 for a free estimate that includes the HVAC scope in the written price.
