A fixed-price addition project from our Plano-based DFW team serving Flower Mound homeowners, with designers, project leads, and tradespeople who finish on the day they said they would. Eleven years, one promise: your quote is your price.
A home addition in Flower Mound typically runs $120,000 to $400,000, depending on whether you build out at grade or add a second story, and how much the new space ties into existing plumbing, HVAC, and the roofline. Permits are pulled through the Town of Flower Mound Building Inspections Division (the town issues these, not Denton County) via its eTRAKiT portal, and any tie-in to plumbing or electrical pulls those trades into the scope. A city-specific cost driver here is the master-planned community standard: in places like Bridlewood, Wellington, and Highland Shores, your addition has to match the original brick, stone, and pitched-roof style closely, which often means custom-matched masonry and HOA architectural review before a permit is granted. On larger Flower Mound lots a ground-level addition is frequently feasible, but the new footprint needs an engineered foundation, which adds engineering and slab cost. For a line-item look at where the money goes, see our DFW remodel cost guide.
We handle survey, setbacks, engineering, HOA and permits before demolition. If your lot cannot take the footprint, you will hear it at the first walkthrough.
Fixed scope and a written schedule before anyone breaks ground in your yard.
Flower Mound grew up fast in the 1990s and 2000s, which means most of the town’s homes were built to a single moment in time, and many families have now outgrown that original floor plan. A home addition is how Flower Mound homeowners get more square footage without leaving the lot, the school, or the neighborhood they chose on purpose. The good news here is space: master-planned enclaves like Bridlewood, Wellington, Highland Shores, and Stone Hill Farms put large move-up homes on generous lots, so there is often real room to build out a primary-suite wing, a bigger family room, a home office, or a second story. UHS Remodeling designs and builds additions that match your existing brick, rooflines, and ceiling heights so the new space reads as original, not bolted-on. With DFW experience dating to 2014 and a fixed-price model, you know the number before we break ground.
We build home additions across Flower Mound, including Willow Bend, Legacy West, Deerfield, Hunters Glen, Russell Creek, and West Flower Mound Estates.
Site walk, scope (bedroom, master wing, second story), zoning + setback review, budget alignment.
Architectural drawings, structural engineer review, exterior match planning, MEP routing.
City of Flower Mound plan review, HOA architectural committee, energy code compliance. Average 3-5 weeks.
Foundation, framing, roof tie-in, MEP rough-in, insulation, drywall, finish-out. 12-22 weeks per scope.
Final inspection, punch list, certificate of occupancy filing, 1-year warranty active.
New slab and framing tied into the existing structure.
Matched brick and tinted mortar at the old-to-new seam.
Design and structural engineering run first, and city plan review plus the HOA architectural committee average three to five weeks before anyone breaks ground.
“An addition in Flower Mound is half permits, half craft. We pre-meet with the city’s plan review before drawings are stamped — that’s why our additions break ground 6 weeks after contract, not 14.”

Which one is right depends on your lot line, your slab and your roof — not on a catalog.
Renderings from our design studies — the finished Flower Mound projects are above.
Ranges include foundation, framing, roof, systems and finishes — everything but landscaping.
All ranges include architectural drawings, engineering, materials, labor, permits, foundation, framing, MEP, finishes, and 1-year warranty. Sourced against NARI Cost vs. Value 2025 and your city building code requirements.
Single-room addition (250-450 sqft): bedroom, office, sunroom. Exterior match, standard finishes, full MEP.
Master wing or large family room (450-800 sqft): primary suite + bath, formal dining add-on, or great room expansion.
Second story or full custom (800+ sqft): structural foundation work, full second floor, matched exterior, custom millwork.
Additions live or die on setbacks, easements and lot coverage — and every DFW city writes those rules differently. We have permitted additions across Flower Mound and the neighboring cities, which means we can tell you in one visit whether the footprint you want is legal on your lot.
We deliver home addition across the northern DFW suburbs. See our home addition in Frisco, Allen, and McKinney.

Most Flower Mound home additions run $120,000 to $400,000. The biggest variables are whether you build a single-story addition at grade or add a second floor, how much new plumbing, electrical, and HVAC the space requires, and how closely the exterior has to match your existing brick and rooflines, which matters in design-controlled communities like Bridlewood and Highland Shores. UHS gives you a fixed price up front so the number does not move mid-project.
Yes. The permit is issued by the Town of Flower Mound Building Inspections Division through its eTRAKiT portal, not by Denton County, because Flower Mound is an incorporated town with its own building department. If your home is in a master-planned community such as Wellington, Bridlewood, or Stone Hill Farms, you will also need HOA architectural review of the exterior before the town permit is approved. UHS handles the building permit and inspections as part of the project.
Often both are options. Many Flower Mound homes in communities like Bridlewood and Wellington sit on sizable lots, so a ground-level addition for a primary suite, expanded family room, or home office is frequently feasible, with an engineered foundation for the new footprint. Where the lot is tighter, a second-story addition adds bedrooms or a bonus space without giving up yard. We design either to match your existing 1990s or 2000s build so the addition looks original.
A home addition in Flower typically ranges from $120,000 to $400,000, depending on size, foundation, and whether it is single- or multi-story.
Yes — every addition we build includes structural engineer review. The cost is included in our fixed quote.
Yes. We source manufacturer-matched brick, stone, and siding. For discontinued lines, we work with local brick dealers to find aged-match material.
Less than a whole-home remodel. We seal the existing house with vapor barriers during framing and only break through the load-bearing wall at the very end of construction.
Yes. We pour all-new slab or pier-and-beam foundation depending on what your existing house uses.
Almost always. We prepare full ACC submissions including elevations, materials samples, and site plans.
Sometimes. We bring in a structural engineer first to check if your existing foundation and load-bearing walls can carry the additional weight.
Yes. Once design is locked and permits are submitted, your price is your price.
North Texas sits on highly expansive clay soil that swells during wet months and shrinks during summer droughts, which can shift foundations by several inches over seasonal cycles. That is why every room addition we build in Flower Mound and Frisco starts with a foundation plan designed by a licensed structural engineer for the specific soil conditions of the lot. Typical solutions include steel-reinforced slab foundations and concrete piers that reach below the active soil zone, so the new addition moves with the original home instead of pulling away from it. Skipping this step is the most common cause of cracked brick, sticking doors, and separated rooflines in DFW additions.
Tell us what you need more of and we’ll walk the lot, check the setbacks, and give you an honest budget range before you commit to anything.
