Rare setting to build your dream home on one of Orienta's rare buildable lots! This is an extraordinary opportunity to build a custom residence from the ground up on a fully cleared, level 0.28-acre parcel in one of Westchester's most coveted waterfront neighborhoods. The property sits just steps from a small public beach on Mamaroneck Harbor; the walk from your driveway to the sand can be counted in steps, not blocks, with water views and walking-distance access to Beach Point Club, Orienta Beach Club, and a short drive to downtown Mamaroneck, and the Metro-North station offering 35-minute express service to Grand Central. The prior structure has been fully demolished and the site cleared in preparation for construction. Mature perimeter trees remain in place, providing established privacy, seasonal beauty, and immediate landscape character that raw land simply cannot match, with the existing driveway intact. The level rectangular envelope comfortably supports a substantial custom residence. The location cannot be replicated, and Orienta lots come to market rarely. The seller has done the difficult work of clearing and preparing the site - what remains is your vision. Per local tax consultant the taxes are projected to reduce to approximately $10,529 in April 2027 based on Mamaroneck's 2026 Tentative Assessment Roll. The property offers municipal water and sewer, an existing driveway and mature perimeter trees.
