Located within one of Water Mill’s most coveted waterfront enclaves, the property offers 160’ of direct frontage+/- and a setting defined by secluded openness. South of the highway and moments from Mecox Beach, Flying Point Beach, and village amenities, the location balances accessibility with a private waterfront presence. Direct access to navigable waters extends the lifestyle beyond the property, allowing for boating, jet-skiing, sailing, kayaking, and paddleboarding right from your own shoreline.
116 Brennans Moor represents a rare opportunity to secure Water Mill’s next notable waterfront estate, with limited time remaining to customize. With its scale, privacy, direct bay frontage, and architectural vision, the property offers a significant Hamptons residence complemented by thoughtfully integrated, state-of-the-art amenities throughout.
The principal living spaces are conceived as expansive volumes of glass and light. A double-height living room serves as the centerpiece of the residence, where a double-sided fireplace and custom-designed bar introduce a refined entertaining element within the space.
At the heart of the home, the kitchen and family room environment is designed as a natural gathering space, supported by a hidden chef’s kitchen and service elements that allow the home to function effortlessly with every amenity.
The primary wing is positioned to capture natural light and outlook, offering a sense of privacy while remaining connected to the residence. The property's western-facing orientation delivers unobstructed sunset views across Hayground Cove, elevating an already exceptional waterfront setting. Pocketing walls of glass, private terrace access, dual walk-in closets, and a spa-like bathroom define a suite designed as a refined retreat within the home.
A 2,400 SF+/- rooftop terrace introduces an elevated entertaining environment with open views across the Bay to the Atlantic Ocean. Designed with multiple lounge seating areas, a dedicated dining area, and a kitchenette, this extensive outdoor oasis provides the perfect setting to enjoy every sunset. Rounded out by an outdoor shower and a four-season putting green, this rooftop creates a distinct outdoor experience that truly balances leisure and recreation.

Outdoor spaces extend naturally from the interiors, creating
a setting designed for both relaxation and entertaining. A heated
knife-edge saline gunite pool with integrated spa anchors the landscape,
complemented by an outdoor kitchen, fire pit and multiple
terraces for dining and lounging.
The attached pool house/cabana is conceived as a fully integrated living environment, offering a lounge, kitchenette, full bath, and wellness area complete with steam, sauna and cold-plunge. Designed as both a private retreat and an extension of the home’s entertaining areas, it enhances the property’s overall experience both indoor and out.
The expansive stone patio and rear entertaining areas lead toward the water, where a private dock extends the property's connection to Hayground Cove, Mecox Bay, and the Atlantic Ocean.
