From the field · Prosper
An addition in Prosper 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.

How much does a home addition cost in Prosper, TX?
+
Home addition costs in Prosper range from $80,000 for a single-room addition (master suite expansion, sunroom, home office) to $750,000+ for a second-story addition or multi-room project. Most Prosper homeowners spend $220,000-$450,000 on a multi-room wing addition.
How long does a Prosper home addition take?
+
Single-room additions take 10-18 weeks including permitting. Multi-room wing additions run 6-11 months including design and permitting. Second-story additions and estate-scale projects take 10-16 months.
Does Prosper allow second-story additions?
+
Yes, second-story additions are permitted in most Prosper residential zones, subject to maximum building height, setback, and lot coverage requirements. Not every original foundation is adequate for a second-story load – we run a structural feasibility check early in design.
Can I convert my garage into living space in Prosper?
+
Yes. Garage conversions are one of the most cost-effective Prosper additions because the foundation, walls, and roof already exist. We convert garages into home offices, playrooms, gyms, and in-law suites. The conversion requires a permit, new flooring, and HVAC/electrical tie-in.
How do you match the exterior of a new addition to an original Prosper home?
+
We source matching or visually identical exterior materials – brick from the same manufacturer or salvaged brick yards, stone matched to the existing, siding and roofing matched. Matching materials may add 3-6 weeks to procurement but ensures the addition does not look bolted-on.
Does Prosper require permits and HOA approval for additions?
+
Yes. The Town of Prosper Building Inspection Department requires permits for any addition. Some Prosper neighborhoods also have HOA architectural review requirements. UHS handles both submissions.
Can I live in my Prosper home during an addition?
+
Usually, yes – especially for rear additions and garage conversions that do not break into the existing home until the final tie-in phase. For second-story additions, most homeowners relocate for 4-10 weeks during structural phases.
Do you handle structural engineering and foundation work?
+
Yes. Every addition we build is engineered by a licensed Texas structural engineer. We handle the full foundation scope and all structural framing including steel beams, load transfers, and second-story floor systems.
Will a Prosper home addition increase property value?
+
Yes. A well-designed Prosper addition typically returns 70-90% of project cost on resale. Master suite expansions and kitchen/great room extensions return close to 100%. An addition also lets a family stay in the neighborhood rather than selling and moving.
