Elevating Flanders: From Bungalows to "New Hampton" Villas

Flanders is a community in transition. Historically known for its mid-century ranches and seasonal cottages near the iconic Big Duck, the area is now seeing a surge in year-round development. At J.B.T Contracting LLC, we are at the forefront of this transformation, helping homeowners convert modest summer bungalows into modern, energy-efficient residences.

Whether you are renovating a secluded property tucked into the pines near the David A. Sarnoff Preserve or building a contemporary estate on the larger lots along Pleasure Drive, we understand the local landscape. We blend the traditional charm of the area with the "New Hampton Style" architecture, featuring expressive windows and sustainable designs, that is becoming popular in newer subdivisions.

BUILDING NEAR THE PECONIC ESTUARY

Overcoming High Water Tables & Septic Regulations

Building in Flanders requires navigating strict environmental codes due to its proximity to the Peconic Estuary. As experienced local contractors, we handle the specific challenges that come with this sensitive ecosystem.
 
  • Navigating I/A Septic Mandates: To protect the estuary from nitrogen pollution, the regulations strictly require Innovative and Alternative (I/A) Onsite Wastewater Treatment Systems for most major renovations. We manage the coordination between sanitary engineers and town officials to ensure your project is compliant.
 
  • High Water Table Solutions: Near Reeves Bay and the riverfront, the water table is often too high for standard full basements. We specialize in designing alternative solutions, such as code-compliant crawlspaces with advanced encapsulation or "slab-on-grade" foundations that ensure structural stability without the risk of flooding.
 
  • Waterproofing: For existing homes with basements, we install industrial-grade waterproofing systems and sump pumps to manage the hydrostatic pressure common in this coastal soil.

EXPANDING YOUR FOOTPRINT

Converting Cottages into Year-Round Homes

Many of the original homes in Flanders were built as modest summer getaways. We specialize in expanding these footprints to accommodate modern, year-round living.
 
  • Ranch & Cottage Extensions: Since building "down" into a basement is often difficult here, we focus on building "out." We design seamless single-story extensions to add master suites, larger kitchens, and family rooms to existing ranches.
 
  • Sustainable "All-Electric" Upgrades: Aligning with the trend toward sustainability seen in the area's new villas, we install energy-efficient windows, updated insulation, and frame out spaces for modern heat pump systems to lower your utility costs.
 
  • Outdoor Living: We take advantage of the natural pine barrens setting by building custom decks and screened-in porches that allow you to enjoy the privacy of the Flanders woods without the insects.
