Preserving Great River’s "Gilded Age" Legacy

Great River is unique on the South Shore, offering a blend of secluded luxury and natural beauty anchored by the historic Bayard Cutting Arboretum. We understand that renovating in "Great River Proper" often involves working on stately Neo-Colonial and Victorian Revival estates tucked behind long, gated driveways. At J.B.T Contracting LLC, we offer the discretion and craftsmanship required for these high-end projects.

However, the area is diverse. For the neighborhoods north of Sunrise Highway, we bring the same level of quality to modernizing the modest Split-Levels and High-Ranches that define the streetscape. Whether you are near the equestrian trails of the Connetquot River State Park Preserve or the fairways of Timber Point, we provide licensed construction services tailored to your specific property type.

PROTECTING THE WATERSHED

Navigating Groundwater Sensitivity & Coastal Rules

Great River is sandwiched between the Connetquot River and the Great South Bay, creating a highly sensitive ecosystem. Renovating here requires strict adherence to environmental mandates to protect the watershed.
 
  • Mandatory I/A Wastewater Systems: Due to nitrogen-reduction mandates, most significant renovations in Great River now trigger the requirement to install Innovative and Alternative (I/A) Onsite Wastewater Treatment Systems. We manage the installation and landscape restoration required to bring your property into compliance.
 
  • Flood Risk Mitigation: With flood risks projected to rise, we specialize in flood-resilient construction. This includes elevating mechanical systems, installing flood vents in foundations, and using water-resistant materials for ground-level renovations near the water.
 
  • Eco-Conscious Construction: We respect the local "Pollinator Pathway" initiatives. When we manage a site, we ensure construction runoff is controlled and work with landscape designers to prepare the grounds for biophilic plantings that satisfy town preservation rules.

CUSTOM DESIGN & BUILD

Historic Restorations and Modern Expansions

Our team is equipped to handle the diverse architectural needs of Great River.
 
  • Estate Renovations: For the Victorian Revivals and Colonials south of Montauk Highway, we provide sensitive restorations. We match custom millwork, restore original siding details, and upgrade electrical/plumbing systems without disrupting the historic aesthetic.
 
  • High-Ranch & Split-Level Updates: For the northern residential pockets, we specialize in opening up floor plans. We remove compartmentalized walls to create modern, airy living spaces that maximize square footage and natural light.
 
  • Equestrian & Outbuilding Construction: Reflecting the area's equestrian heritage near the State Park, we also design and build custom carriage houses, detached garages, and barns that complement the main residence.
