Virtual Tour
Set on the ocean and completed in 2023 after a five-year design and build process with renowned New York architects Thomas Phifer and Partners, this gated oceanfront estate is a striking modern retreat seamlessly integrated into its natural dune landscape with unobstructed views to the east. Conceived as a private sanctuary, the residence is discreetly tucked into the coastal scenery, ensuring a rare sense of peace and seclusion. Designed as a pale-concrete platform embedded within the dunes, the home is composed of three glass-walled pavilions-each framing panoramic views of the Atlantic and serving as distinct living spaces connected by a dramatic concrete passageway. An elevated private path leads directly from the estate to a pristine stretch of ocean beach with 200 +/- feet of direct frontage, offering effortless access yet complete privacy. Surrounded by native pine, bayberry, and beach plum, the landscape enhances the feeling of a retreat that has emerged organically from its environment, shielding the residence from view while heightening its connection to nature. Inside, light-filled interiors balance glass, steel, and concrete with organic, artisanal, and textural elements, creating a refined yet inviting living environment. The main pavilion encompasses an open kitchen with dual islands, a dining area, and an adjacent sitting area, all oriented toward expansive ocean vistas. Additional living spaces include a den/office and thoughtfully designed bedrooms for family and guests. The primary suite occupies its own glass pavilion, offering sweeping vistas, a serene sitting area, and an expansive spa-like bathroom. With its gated entry, discreet setting, direct beach access, and a design that marries modern architecture with the raw beauty of the Hamptons coastline, this oceanfront residence is an architectural and lifestyle statement of the highest caliber.
