Life on the North Fork doesn't get better than this!

Thoughtful upgrades include radiant floor heating, ducted heating and cooling with remote access, marble countertops, updated mirrors and light fixtures, keyless entry, Sonos speakers, and a beautifully appointed chef's kitchen. The primary suite includes a gorgeous bathroom, featuring a sculptural egg-shaped soaking tub perfectly positioned to capture the sunset views, separate shower and double sinks.

A rare grandfathered lower waterfront platform creates an extraordinary setting at the water's edge for cocktails, Pilates, or simply taking in the sights and sounds of the Sound. The outdoor audio system extends the experience all the way to the property's iconic Whale Rock. Additional highlights include a detached garage offering potential for conversion into additional living space with proper permits. With dramatic water views, unforgettable sunsets, and a lifestyle centered around the Sound, this is North Fork waterfront living at its finest.
