Overview
Home Additions in Princeton — for homeowners in Mercer County, built by a team that lives here.
Princeton is home to one of the world's most prestigious universities and some of Central New Jersey's most distinguished residential architecture. From stately Colonial homes along Nassau Street to mid-century ranches in the Western Section, Princeton properties carry both historic significance and substantial market value. Many homeowners here need renovations that honor original craftsmanship — crown molding profiles, hardwood floor restoration, period-appropriate kitchens — while quietly integrating modern systems behind the walls.
Princeton homeowners invest in their properties because values here consistently outpace the rest of Mercer County. Whether you own a 1920s Tudor near the university campus, a stone farmhouse off Cherry Hill Road, or a newer build in Montgomery, renovation ROI in Princeton is among the highest in the state. Local zoning and historic district regulations also mean you need a contractor who understands permit requirements beyond standard NJ code.

Every additions project covers the full scope — start to finish.
One contractor pulls every trade under one roof — design, demolition, rough-in, finish, cleanup. You deal with the owners. No coordinating subs, no finger-pointing, no surprise line items.
