0 Charach & 1 West Walk, Water Island, NY 11706 Tucked between The Fire Island Pines and Davis Park lies Water Island. With only 48 homes adjacent to the protected Fire Island National Seashore; Water Island creates a unique sense of remoteness and natural beauty — a true retreat for those seeking to unwind in quiet luxury. This secluded enclave offers 200 feet of unobstructed Atlantic Ocean frontage; rare privacy and direct access to pristine beaches, all within an easy commute from New York City. Rooted in the ethos of Parrot Cay, Big Sur, and Amangiri, and deeply influenced by the craftsmanship and philosophies of George Nakashima and Hans Wegner, this expansive retreat is a study in balance — where modernist clarity meets organic warmth. The design embraces a sense of quiet luxury drawn from these iconic places: the barefoot elegance of Parrot Cay, the raw natural beauty of Big Sur, and the sculpted minimalism of Amangiri. The One-Bedroom Main House, a private and reimagined sanctuary for the Owners, sits nestled in the dunes. Inside, a warm composition of cedar and teak woods, white walls, and diffused light creates a tranquil atmosphere. The first floor serves as a serene sleeping suite, where spa-like bathing spaces are seamlessly integrated into the flow of everyday living. Above, the second floor opens fully to the landscape with expansive floor-to-ceiling windows and sliding glass doors that dissolve the boundary between indoors and out. Here, the Atlantic Ocean becomes both backdrop and focal point — a constant, calming presence, framed by architecture that gives it space to breathe. Oriented toward the coastline, the main living spaces maintain a constant connection to the ocean, making it an integral part of the home’s daily life. A meandering path through the sand joins the main house with the four-bedroom three bath guesthouse on the adjacent lot, a relaxed social hub featuring a bar, sun decks, an outdoor kitchen, and a pool — all designed to encourage barefoot living and effortless hospitality. From the moment you step inside the guest quarters you are enveloped by the integration of architectural elements – cool stainless steel, warm-toned woods, and white walls and ceilings – creating a layered, modern aesthetic. This interplay of textures brings depth and sophistication, blending functionality with high design for a space that feels both curated and comfortably livable.
