Set prominently along the coveted shoreline of Rowayton, this extraordinary residence is a true architectural masterpiece that defies the standard coastal trope. Designed by award-winning Cardello Architects, the home is a fortress of design-a structural marvel built with an uncompromising integrity that feels as permanent as the tides. The silhouette is bold and commanding, yet every element reflects a sophisticated functional design that breathes with the rhythm of the Long Island Sound. Inside, a dramatic glass staircase and double-height foyer serve as a transparent focal point, leading to sunlit interiors that act as curated galleries for sweeping waterviews. Throughout the home, Venetian plaster and wide-plank white oak meet industrial precision, while 9 -foot glass doors blur the line between the chef's kitchen-outfitted with Poggenpohl cabinetry and Sub-Zero appliances-and the horizon. The primary suite offers a serene retreat featuring cathedral ceilings, a gas fireplace, and a spa-like bathroom and walk-in closet that rival the world's finest hotels. The grounds are an amphitheater for the elements. Expansive 9-foot glass doors sweep open to a spectacular party deck, where a full outdoor kitchen and fireplace are anchored by a dramatic 18-foot fire wall. This glowing pillar stands in bold contrast to the resort-style spa and heated gunite pool with its dual shallow lounging areas. Beyond the aesthetics, this is a high-tech bastion powered by geothermal efficiency and a full Crestron system. Functional luxury is woven into the structural fabric, from radiant heated floors and an elevator serving every level to fogging glass that provides instant, effortless privacy. The retreat is completed by a movie room, golf simulator, and a spacious 3+ car garage, offering a rare duality: the security of a modern sanctuary set against the most tranquil waterfront backdrop in Rowayton. Moments from the village, beach, and train, this is a rare opportunity to experience the intersection of architectural strength and the sea.
