A fixed-price addition project from a Plano-based crew of designers, project leads, and tradespeople who finish on the day they said they would. Eleven years, 5,875 projects, one promise: your quote is your price.
A home addition in Plano typically runs $120,000 to $400,000, depending on size, foundation work, and whether you build out or up. A modest single-room addition lands near the low end; a multi-room or second-story addition with structural and roofline changes pushes toward the top. Additions are permitted through the City of Plano Building Inspections Department under its “Residential Additions & Alterations” category, and that review matters here: many West Plano lots in older enclaves carry HOA architectural standards plus mature trees and existing brick that the new wing must match. A city-specific cost driver for Plano additions is tying into 30-40-year-old (median build ~1993) structures and mechanical systems on established lots, where matching original brick, extending the foundation, and rerouting plumbing or HVAC on an aging home adds scope a new build never sees. UHS quotes a fixed price up front so the figure does not move mid-project. For a line-item look at where the money goes, see our DFW home remodel cost guide.
Plano’s neighborhoods were largely built out in the 1980s and 1990s, with a citywide median home age around 1993 (West Plano enclaves like West Plano Estates skew even older, near 1985). That means a lot of Willow Bend, Deerfield, Russell Creek, and Hunters Glen homes are now 30-40+ years old, sitting on mature lots that were generous by today’s standards but with floor plans that feel tight for modern families. A home addition is how many Plano owners get more square footage without leaving Plano ISD or a street they love. UHS Remodeling builds room additions, second-story additions, primary-suite expansions, and great-room bump-outs across Plano, matching the existing brick “New Traditional” and ranch elevations so the new space reads as original. We have completed 5,875+ DFW projects since 2014 with a fixed-price model and a 3-year workmanship warranty.
We build home additions across Plano, including Willow Bend, Legacy West, Deerfield, Hunters Glen, Russell Creek, and West Plano Estates.
“An addition in Plano 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.”
All ranges include architectural drawings, engineering, materials, labor, permits, foundation, framing, MEP, finishes, and 3-year warranty. Sourced against NARI Cost vs. Value 2025 and City of Plano building code requirements.
