Overview

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

Montgomery Township is an affluent residential community adjacent to Princeton, known for top-rated schools, preserved farmland, and upscale neighborhoods like Belle Mead and Rocky Hill. Homes here range from historic stone houses along Route 206 to executive colonials and custom builds on multi-acre lots in newer developments. The township attracts families willing to invest significantly in their homes.

Montgomery homeowners expect premium renovation quality — custom cabinetry, natural stone, high-end fixtures, and meticulous finish work. Many projects here involve transforming dated 1990s builder-grade interiors into spaces that match the affluent character of the community. The township's rural-suburban mix also creates demand for outdoor living projects: expansive decks, screened porches, and outdoor kitchens taking advantage of private wooded lots.

Scope of work

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.
