AfterFast, Reliable Home Additions & ADU Across Trophy Club
A home addition or ADU in Trophy Club typically runs between $45,000 and $130,000 for the build itself, with detached ADUs landing higher because of site work, utility trenching, and the town’s two-stage approval process. The biggest scheduling factor here isn’t the framing crew. It’s the HOA’s Architectural Review Committee, which has to sign off before the Town of Trophy Club will even look at a permit application. If you already live in Trophy Club, you know exactly what we’re talking about. If you’re new to the area, we’ll walk you through it before you spend a dime. Call (877) 610-1318 and we’ll come out, walk the lot with you, and tell you straight what’s possible.
We’re Barrett & Sons Construction, founded in 1998 and still run by Tom Barrett. Our Home Additions & ADU team has worked on additions, garage conversions, and detached units in the 76262 zip code for years. We know which Trophy Club streets slope toward the golf course, which lots sit on the worst of the black clay, and what the ARC tends to flag on a first review. That local knowledge is the difference between a project that starts in six weeks and one that stalls for six months.
Why Barrett & Sons Construction Is Trophy Club’s Preferred Home Additions & ADU Company
Trophy Club isn’t a place where you can park a dumpster on the driveway and figure it out as you go. Every exterior project here runs through the HOA’s Architectural Review Committee first, and the Town of Trophy Club won’t accept a permit application without that prior written approval. We’ve been through that sequence enough times to prepare drawings and scopes that clear the first review more often than not. It saves you weeks.
Tom Barrett’s name, address, and license number are published and verifiable. He and his sons are on-site most days. That matters in a town where the neighbor asking about your addition might be the same person who sits on the review committee. Our Trophy Club Roofing customers tell us the same thing: they’d rather pay a fair price to a contractor who picks up the phone than chase a low bid from someone who disappears after the deposit. And every job, every scope, every allowance arrives in writing before work starts. If it’s not done right, our 90-Day Done Right Promise brings Tom back. One call.
We serve all of Trophy Club, including the neighborhoods backing up to the Country Club golf course and the newer streets near the northern town limits. You’ll see our trucks at the hardware store on a Saturday. We’re not dispatching strangers from two counties over.
Our Home Additions & ADU Services in Trophy Club
ADU Design & Permitting
Before any wall goes up, we handle the two-step approval that Trophy Club requires: HOA Architectural Review Committee submission first, then the Town of Trophy Club building permit. We draw plans that match the deed restrictions for your specific lot, prepare the site plan and drainage narrative the committee wants, and follow the application through to approval. Homeowners who try to skip the ARC step get stop-work orders. We don’t let that happen.
Garage Conversion ADU
A garage conversion in Trophy Club usually runs $30,000 to $80,000, depending on whether you need a new bathroom stub, kitchenette, or separate HVAC. Trophy Club homes built in the 1990s and 2000s often have oversized attached garages with enough square footage for a comfortable one-bedroom unit. The catch is the HOA: many Trophy Club deed restrictions require that converted garages maintain a certain exterior appearance, which affects Windows & Doors - Trophy Club placement and choices. We design around those rules from day one.
New Detached ADU
Building a detached ADU in Trophy Club runs $90,000 to $220,000. That range reflects site work more than anything: grading on shrink-swell clay, utility trenching, and drainage design that satisfies both the HOA landscaping standards and the golf course runoff policies if your lot backs up to the course. Because Trophy Club sits on expansive black clay, we over-excavate and engineer footings more conservatively here than we would in, say, Roanoke. It adds cost but prevents the hairline cracks and door-stick issues that show up on underprepared slabs within two wet-dry cycles.
Junior ADU & Interior Conversion
The fastest path to extra living space in Trophy Club is converting interior square footage you already have: a bonus room over the garage, a formal dining room that never gets used, or an oversized utility room. These conversions usually stay under the main home addition range of $45,000 to $130,000, and because there’s no exterior footprint change, the HOA review is often simpler. You still need the Town permit for any plumbing or electrical work, and we pull every permit on every eligible job, no exceptions.

Trusted Brands We Service in Trophy Club
We don’t install mystery materials off a van. On Trophy Club additions and ADUs we regularly specify GAF roofing systems, Schluter waterproofing in any wet area, and Grohe fixtures where clients want German engineering without the showroom markup. If you’re doing an addition that includes a kitchen or bath, we also handle Kitchen Remodeling in Trophy Club and Bathroom Remodeling in Trophy Club as part of the same scope, so you’re not juggling three contractors on one job site. We stock common parts and materials locally, so a missing drain assembly or flashing detail doesn’t idle a crew for three days.
Common Home Additions & ADU Problems We See in Trophy Club Homes
- ARC rejection on first submittal. Trophy Club’s HOA review is stricter than most neighboring towns. Out-of-area contractors routinely submit incomplete landscape and drainage plans, get bounced back, and the homeowner loses a month. We submit complete packages the first time.
- Foundation movement on black clay. The shrink-swell soil under much of Trophy Club shifts with every wet-to-dry season. An addition with shallow footings or poor drainage will show cosmetic cracks within two years, and doors will start to bind. We over-engineer footings and manage drainage as a core part of the build, not an afterthought.
- Golf course runoff crossing the property line. Lots backing up to the Trophy Club Country Club golf course face stormwater from fairways and greens. An addition that doesn’t account for that runoff can end up with a soggy crawlspace or flooded patio. We coordinate grading and drainage with both HOA standards and the club’s policies.
- Roofline and elevation mismatches. Trophy Club’s 1990s and 2000s brick-veneer homes have specific rooflines, and a poorly planned second-story addition can leave a visible seam that tanks curb appeal and HOA goodwill. We tie new rooflines into the existing structure so the addition looks original from the street.
Pricing for Home Additions & ADU in Trophy Club, TX
For planning purposes, a main home addition in Trophy Club runs $45,000 to $130,000. A garage conversion ADU runs $30,000 to $80,000, and a new detached ADU runs $90,000 to $220,000 once you factor in site prep, utility runs, and drainage on North Texas clay. What moves the number most is foundation work, the HOA-required exterior cladding, and whether you’re adding a bathroom or kitchen to the new square footage. A simple room addition with no plumbing lands at the lower end. A detached ADU with a full bath, kitchen, separate HVAC, and golf-course drainage coordination lands at the top.
We write every scope, every allowance, and every change order in writing before we start. An allowance that isn’t on paper is a surprise waiting for a date. You’ll get a line-item estimate, not a phone number and a handshake. Call (877) 610-1318 to schedule your free estimate. No trip charge inside the county, and a free second opinion on any written estimate you already have.

FAQs - Home Additions & ADU in Trophy Club
The HOA Architectural Review Committee review plus Town of Trophy Club permitting usually takes 6 to 10 weeks for an addition or detached ADU before construction can begin, though interior-only conversions can clear faster. We submit complete plans the first time, which avoids the month-plus delays that come from ARC rejections and resubmittals. Call (877) 610-1318 and we’ll give you a realistic timeline for your specific lot after a site visit.
Yes. We handle additions and ADUs throughout the 76262 zip code, including homes backing up to the Trophy Club Country Club golf course. Golf course lots require extra drainage coordination with the club’s runoff policies, and we manage that as part of the scope, not as a surprise change order later.
A main home addition in Trophy Club runs $45,000 to $130,000, which is roughly in line with Southlake and slightly above Keller or Roanoke because of the HOA-approved exterior materials and clay-soil foundation engineering. Detached ADUs run $90,000 to $220,000. We’ll give you a line-item estimate after walking the lot, and any deviation from that number arrives as a written change order before work proceeds.
We handle both. We submit to the Trophy Club HOA Architectural Review Committee first, because the Town of Trophy Club will not accept a permit application for exterior work without prior written ARC approval. We pull every municipal permit on every eligible job and make sure inspections are signed before you make the final payment. The permit inspector works for you, not for us. That’s why we like him.
Every completed job carries our written 90-Day Done Right Promise. If something isn’t right, Tom Barrett comes back and makes it right. One call to (877) 610-1318, and it’s handled. That guarantee is written on the contract, not buried in fine print.
Need a straight answer about whether your Trophy Club lot can support an addition or ADU? Call (877) 610-1318 today.
