A home addition in Murphy typically runs $120,000 to $400,000, depending on whether you are bumping out a single room, adding a primary suite, or building a full second story. Larger, more complex additions on Murphy’s bigger homes can push past that range. Permits are pulled from the City of Murphy Building Inspection Division (Permits & Inspections) at City Hall, not Collin County, since Murphy is an incorporated city. The biggest Murphy-specific cost driver is the housing itself: these are large early-2000s brick homes with open floor plans, so a new room or suite has to tie into an existing foundation, match brick and rooflines that may be hard to source 15-25 years later, and clear architectural review from a mandatory HOA before work begins. Engineered foundations for room additions add design cost. UHS prices each addition as a fixed number, with a 3-year workmanship warranty. For a line-item look at where the money goes, see our DFW remodel cost guide.
Murphy is a community of large, brick-clad single-family homes, and that makes it one of the best places in Collin County to add square footage. Roughly three-quarters of the city’s homes were built after 2000, during the boom that followed the President George Bush Turnpike, so most are now 15-25 years old and sitting on the generous lots and open floor plans of planned subdivisions like Maxwell Creek, Rolling Ridge Estates, and Murphy Farms. Many already have four, five, or six bedrooms, yet families still outgrow them. A home addition lets you stay in your neighborhood, your Plano ISD or Wylie ISD school zone, and your yard near Murphy Central Park while gaining a primary suite, a sunroom, a bonus level, or an in-law wing. UHS Remodeling has built additions across DFW since 2014 on a fixed price.
We build home additions across Murphy, including Maxwell Creek and Maxwell Creek North, Rolling Ridge Estates, and Murphy Farms, plus established homes near Murphy Central Park and along FM 544 between Plano and Wylie.







“An addition in Murphy 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 design, materials, labor, permits, and 3-year warranty. Sourced against NARI Cost vs. Value 2025 regional benchmarks.
