About this home

Life on the North Fork doesn't get better than this! Set along the Long Island Sound in one of Southold's most desirable locations, this chic waterfront escape offers sweeping water views, sensational sunsets, and effortless coastal living. Renovated in 2016 and completely move-in ready, the home blends sophisticated style with relaxed comfort, creating the perfect setting for both entertaining and quiet moments by the sea. 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. The primary also has an office nook, and custom walk-in closet. Outdoor living is at the heart of the property. An expansive sun deck provides ample space for dining, lounging, entertaining, or morning yoga, while private stairs lead directly to the sea. 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.
