Home Additions in Durham, NC
Expand your living space with a properly designed and built home addition — room additions, suite additions, sunrooms, and more.
Durham homeowners love their neighborhoods and often prefer to expand their current home rather than leave. Billy Weatherspoon Contractor has been building home additions in Durham for over 40 years — room additions, master suites, sunrooms, and garage conversions — helping homeowners get the space they need without the disruption of moving.
We manage permits, structural engineering coordination, foundation work, framing, roofing, and all interior finish work. Our goal is to tie the new addition into your existing home so seamlessly that it looks like it was always there — matching rooflines, exterior finishes, trim, and flooring throughout.
