Custom Home Builder in the Hamptons
Building a custom home in the Hamptons means more than construction — it means translating a lifestyle into a livable, lasting residence. 1640 Management is a boutique custom home building and construction management firm based in Southampton, NY, working with homeowners throughout Southampton, Bridgehampton, Sag Harbor, Sagaponack, Water Mill, Wainscott, and East Hampton.
Led by founder Brad Grossman — who has built and renovated over 100,000 square feet of custom luxury properties across the Hamptons, New York City, and the North Shore — 1640 Management brings two decades of hands-on real estate development, construction, and hospitality experience to every project.
What Sets a Custom Home Builder Apart
Unlike production builders working from a limited set of floor plans, a true custom home builder in the Hamptons starts with your land, your lifestyle, and your architectural vision — then builds a team of architects, designers, and tradespeople around that vision. At 1640 Management, every project begins with careful land planning: evaluating topography, wetlands, flood zones, soil conditions, and local zoning before a single foundation is poured.
Our Custom Home Building Process
- Land Planning & Feasibility — Site analysis, zoning review, and privacy/view planning tailored to Hamptons regulations.
- Design Build Integration — Architecture, engineering, and construction coordinated under one team, reducing delays and miscommunication.
- New Construction — Full-service ground-up building, from permitting through final walkthrough.
- Concierge Property Management — White-glove maintenance and vendor coordination once your home is complete.
