SERVING THE 11963 COMMUNITY

Preserving Sag Harbor’s Whaling Heritage

Sag Harbor is arguably the most architecturally distinct village on the East End. From the dense core of 18th-century Greek Revival mansions and Whaling Captain's cottages near Main Street to the mid-century cottages in the historic SANS subdivisions (Azurest, Sag Harbor Hills, Ninevah Beach), every street tells a story.

At J.B.T Contracting LLC, we specialize in the delicate balance required here. We understand that a renovation near the Watchcase Factory condos has different requirements than a project in Noyack.

Whether you are preserving a historic façade or building a "Hamptons Farmhouse Fusion" extension that blends modern glass with traditional wood, we deliver the licensed craftsmanship that honors the village’s character.

NAVIGATING THE BHPAR

Historic Approvals and Complex Foundations

Building in Sag Harbor means navigating some of the strictest codes on Long Island. We guide homeowners through the "red tape" to get projects moving.
 
  • Historic Board (BHPAR) Compliance: The Board of Historic Preservation & Architectural Review has strict oversight on exterior changes. We specialize in sourcing historically accurate materials, like custom cedar shingles and period-correct window profiles, to ensure your renovation passes board review without costly delays.
 
  • Complex Site Conditions: Sag Harbor’s history as an industrial port means ground conditions can be challenging. When digging foundations for extensions or managing site work near the village center, we carefully coordinate the masonry and excavation process to ensure structural integrity and site safety.
 
  • SANS District Sensitivity: We understand the cultural significance of the Azurest and Ninevah Beach neighborhoods. We help homeowners modernize these cottages for year-round living while respecting the scale and aesthetic that defines these historic communities.

CUSTOM DESIGN & BUILD

Merging 18th Century Charm with Modern Living

We tailor our renovation strategies to the unique "Village vs. Coast" dynamic of Sag Harbor.
 
  • "Farmhouse Fusion" Extensions: A popular trend in Sag Harbor is attaching minimalist, modern extensions to traditional homes. We build these glass-and-wood additions that flood the home with light while contrasting beautifully with the original historic structure.
 
  • Historic Restoration: For the Greek Revivals and Captain's cottages, we provide authentic restoration. We repair rotted cornice details, restore original pine flooring, and update plumbing and electrical systems without damaging the home's "bones."
 
  • Luxury Interiors: Whether overlooking the marina near Faraway Sag Harbor (formerly Baron's Cove) or tucked away on a quiet lane, we create high-end interiors featuring custom millwork, marble baths, and chef’s kitchens that fit the "Coastal Chic" aesthetic.
