Tucked along the quiet North Fork shoreline, this luxury modular home in Riverhead, New York showcases how prefabricated construction and refined coastal design can live beautifully together. Fabricated offsite by Signature Building Systems, this prefabricated residence brings contemporary craftsmanship to one of Long Island’s most sought-after coastal neighborhoods, where traditional labor shortages and high site costs make modular efficiency a natural fit.
Just a half mile from the beach and 200 yards from a deep-water marina, this home blends relaxed coastal living with modern amenities. The traditional cedar-shake exterior and covered porch open to a bright, open-concept interior with 7-inch white oak floors, gas fireplace, and Thermador chef’s kitchen. The 3-bedroom, 2.5-bath layout includes a marble primary ensuite with double vanity and custom closets.

With 9-foot first-floor ceilings, Anderson 200 Series windows, and Wolf Designer white cabinetry, the home achieves the clean, timeless look of custom coastal architecture while maintaining modular precision from floor to ceiling.
While the 9-foot ceiling basement (with two egress windows) offers the potential for two additional bedrooms, supported by a five-bedroom septic system.
Outdoors, a 16×32 heated gunite saltwater pool sits amid professional landscaping and accent lighting, creating a true resort-style retreat. A tropical hardwood front deck completes the home’s warm and inviting curb appeal.
Crafted in Moosic, PA — Delivered to the North Fork
Signature fabricated the four modules for this 2,200-square-foot, two-story residence inside its controlled facility in Moosic, Pennsylvania.
By completing the structure off-site, Signature and Town & Country overcame the area’s limited labor pool and high subcontractor costs — delivering luxury faster, cleaner, and with less disruption to the quiet Jamesport neighborhood.
The design was initially based off of Signature’s 1,800 SQFT two story Willow floor plan and customized to fit the Long Island community and the homeowner’s needs.
Durability Meets Design
Modular construction offers more than schedule certainty; it provides inherent resilience. Each Signature module is built for structural strength and air-sealed performance, ensuring comfort in Riverhead’s coastal climate. From energy-efficient framing and insulation systems to rigorous quality control at every stage, this home demonstrates why modular is the smarter path for coastal construction — particularly in regions where weather and workforce shortages can slow traditional projects.
