Overview

This exceptional waterfront property sits on a private 22‑acre peninsula on the west side of Stonington’s Wamphassuc Point. Originally built in 1973 by a member of one of America’s most prominent industrialist families, the estate occupies one of Southern New England’s most coveted coastal locations. The site combines sweeping, unobstructed views across Fishers Island Sound with a preserve-like natural setting and more than 3,000 feet of shoreline.

Waterfront and Dock

The property offers dramatic water frontage and panoramic vistas that reach as far as Montauk Point. A magnificent 130-foot Ipe dock was constructed in 2020 and includes a motorized lift currently configured to accommodate a 40-foot powerboat. The dock and shoreline access make the estate ideal for boating, swimming, birding and other coastal activities while preserving the privacy of the single-family compound.

Improvements and Potential

The current owners have invested approximately $3 million in significant improvements across the estate, including the new dock, two architecturally designed studios and extensive landscaping focused on restoring native species and habitat. The two studios are crafted to reflect the architectural language and design vision envisioned for the main residence and serve as high-quality examples of the permitted aesthetic.

Importantly, there are approved plans to reconstruct the primary residence into a substantially larger estate of over 10,000 square feet of livable space located outside the flood zone. These plans present a rare opportunity to realize a major new residence on a peninsula that already offers deep, protected water frontage and exceptional privacy.

Setting and Privacy

Most of the peninsula remains in its natural state, surrounding the single private home and creating a preserve-like environment that supports local flora and fauna. Given its location in the New York–Boston corridor and the combination of shoreline, seclusion and approved expansion plans, this property is among a very small number of comparable private waterfront compounds in the region.
