Additions in New Castle

What additions projects look like in New Castle

The New Castle homes we work in are mostly 1700s–1960s, with strong historic stock, typically Federal-style, historic colonials, and post-war ranches. We've completed projects across Old New Castle, Penn Acres, and Buttonwood.

Working in Old New Castle's historic district often requires HARB (Historic Area Review Board) approval, we handle those submissions and have a track record of getting plans approved without scope cuts.
