Overview

Home Additions in Flemington — for homeowners in Hunterdon County, built by a team that lives here.

Flemington is the county seat of Hunterdon County, known for its historic downtown, the landmark courthouse where the Lindbergh trial took place, and a revitalized Main Street with restaurants, boutiques, and craft breweries. The borough's residential streets feature a well-preserved collection of Victorian, Federal, and Colonial Revival homes, many listed on the National Register. Newer developments on the outskirts offer colonials and townhomes for families seeking Hunterdon County schools.

Flemington renovation projects often blend preservation with modernization — updating kitchens and bathrooms inside 19th-century homes while maintaining historically compatible exteriors. The borough's revitalization has increased property values and renovation investment. Newer homes on the edges of town need the builder-grade upgrades common to 1990s and 2000s construction. Flemington's building department is familiar with historic-context work and expects quality permit applications.
