Expert Home addition construction in Cary, NC

When your Cary home no longer fits your life, a well-planned addition is often the most practical path forward. Firm Foundations Homebuilders handles home addition construction from initial planning through finished build. We work on primary suite additions, in-law suites, home office expansions, family room extensions, and second-story additions. Cary has its own Inspections and Permits Department, separate from Wake County, and every addition that changes a home's footprint requires a building permit, site plan, and review against the 2018 NC Residential Code. Many Cary neighborhoods also carry HOA architectural review requirements that affect exterior design and rooflines. We account for all of that before a single wall goes up. Owner Erik brings a background in architecture and home inspection to every project. That combination means he reads existing structures carefully, spots what needs to be addressed before construction starts, and designs additions that connect to your home the way they should. If you are ready to add space in Cary, call us to talk through your project.
