Bump-outs, sunrooms, primary suites, in-law quarters, and full second stories — designed, engineered, permitted, and built by one DFW design-build team. Since 2014, 5,875 projects, one promise: your quote is your price.

A full room addition in Dallas–Fort Worth runs $120,000 to $400,000+, while bump-outs, sunrooms, and garage or attic conversions cost considerably less. A single-room addition (bedroom, bath, office) averages $120K–$180K; a primary-suite wing or large family room $180K–$280K; a second story or full custom addition $280K–$400K+. Permits, foundation, framing, MEP, and finish-out are included, with a fixed written price before demolition.

“An addition is really a tie-in — new foundation, roofline, and HVAC married to a house that’s been moving for twenty years. We engineer that connection before contract, so the price you sign already accounts for what’s behind the wall.”
All ranges include architectural drawings, engineering, materials, labor, permits, foundation, framing, MEP, finishes, and a 3-year warranty. Benchmarked against NARI Cost vs. Value 2025. For a full line-item breakdown, see our DFW addition cost guide.
