Property Description

Located in coveted Orienta Point, this exceptional brick Colonial is set on Indian Creek with direct access to Long Island Sound and 1.09 acres of beautifully landscaped grounds. Combining timeless architecture with expansive, light-filled interiors, the home showcases dramatic floor-to-ceiling arched windows, soaring ceilings, and exquisite custom millwork throughout. Spanning over 5,700 square feet across three levels, it is designed for both grand-scale entertaining and comfortable everyday living, with most of the rooms capturing views of the water, pool or surrounding manicured property. The layout offers exceptional flexibility, anchored by an expansive first-floor primary suite with direct outdoor access, multiple family rooms and gathering spaces, and a beautifully renovated gourmet chef’s kitchen with custom cabinetry and professional-grade appliances. The fully finished lower level with separate entrance adds tremendous versatility, featuring a second kitchen, recreation spaces, a full bath and additional finished rooms ideal for guests, work-from-home, gym, or extended living. Outdoors, the property lives like a waterfront retreat. A heated pool, beach, boat dock, bluestone seawall, and pool shed with outdoor shower and changing area create a perfect setting for extraordinary summers. Additional highlights include Sonos sound system, smart thermostats, programmable sprinkler and pool systems, natural gas hookup for outdoor grilling, and a three-car garage with unfinished space above offering expansion potential. All just minutes from Harbor Island Park, beach clubs, golf, schools, village shops and restaurants, and the Metro-North train to Manhattan, this is a rare opportunity to own a truly special property in one of Mamaroneck’s most sought-after neighborhoods.
