About this home

An extraordinary opportunity to build your dream waterfront home on the shores of beautiful Lake Mahopac. Offering direct lake frontage with breathtaking water views, this rare property combines the excitement of new construction with the value of significant existing improvements already in place. The property features a usable existing foundation from the previous 2,500+ square foot home with an attached garage, along with municipal water and an existing septic system—providing an exceptional starting point for your custom lakefront residence. One of the property's most coveted features is the grandfathered boathouse and private dock, an increasingly rare amenity that offers immediate access to boating, fishing, kayaking, paddleboarding, and everything Lake Mahopac has to offer. Positioned on the desirable west side of the lake, the property enjoys beautiful sunrise views reflecting across the water and a front-row seat to the peaceful beauty of lakefront living. Whether you're relaxing by the shoreline, entertaining on the dock, or launching your boat for an afternoon on the water, this is a setting designed to be enjoyed year-round. At approximately 0.14 acres, this is a truly unique chance to create a custom waterfront retreat in one of the Hudson Valley's most sought-after lake communities. Waterfront building opportunities with an existing foundation, grandfathered boathouse, private dock, municipal water, septic, and spectacular lake views are exceptionally rare. Bring your architect, your builder, and your vision—and create the lakefront home you've always imagined.
