Live beautifully, by the shore. Introducing this sleek new 2021 architectural stunner with soul-soothing views of Long Island Sound and private beach access just steps away. This striking coastal retreat is peacefully positioned on large, lush .39 acre grounds at the end of a private cul-de-sac in the desirable enclave of Orienta Point - where the only sound is the gentle sea breeze!

The family room is stunning and offers direct access to the backyard, complemented by a light-filled office, a chic powder room, and an au pair or guest room with ensuite bath. On the 2nd-floor are three bedrooms, one with an ensuite, and two that share a full hall bath with twin vanities, plus a conveniently located laundry. Up a few steps on its own level, the primary suite lives like a private sun-drenched sanctuary with panoramic water views, a dreamy wraparound deck, exercise room or 2nd office, a resort like ensuite, and a walk-in closet to rival a designer boutique. On the lower-level is a spacious mudroom with storage and access to the 2-car garage. Modern comfort meets sustainability with a whole-house generator, solar panels, and a state-of-the-art geothermal heating and cooling system—delivering peace of mind, energy efficiency, and long-term savings. This home is peace and serenity, steps from the water, yet close to downtown Larchmont and Mamaroneck, to schools and the train to NYC!
