The Colony home additions are one of the most cost-effective moves a homeowner can make in this market. The Colony is a fast-growing lakefront city on Lake Lewisville with roughly 44,000 residents. Most homes here were built between 1990 and 2015 as master-planned communities. The Colony homeowners are typically young families who relocated from Frisco or Plano for the schools and lake access. Rather than selling and buying a bigger home at today’s interest rates, adding 300–1,500 sq ft onto an existing The Colony home typically delivers better financial value and lets the family stay in the neighborhood, schools, and commute they already like.
At UHS Remodeling, we handle every phase of The Colony addition projects: feasibility studies (lot coverage, setbacks, HOA review where applicable), architect and structural engineer coordination, The Colony Building Inspection Department permitting, excavation and foundation work, framing and structural, envelope matching (brick, stone, siding, roofing), full interior finish, integration with existing HVAC/electrical/plumbing systems, and final punch-list. Every project is delivered with one dedicated W-2 crew, fixed-price contracts with full line-item transparency, daily photo updates, and a written 3-year workmanship warranty.
This tier covers targeted additions that solve a specific need without reshaping the home. Scope includes: master bedroom expansion, walk-in closet addition, sunroom or screened porch, rear family room, home office addition, mudroom and laundry expansion, dedicated playroom or home gym, or primary bathroom expansion. Typical size: 250–600 square feet. Timeline: 10–18 weeks.
