21515 Soundview Avenue, Southold, NYVideo Tour of 21515 Soundview Avenue, Southold, NY.
Southold chic Soundfront escape in one of the area's most desirable locations, offering sweeping water views, sensational sunsets, and effortless North Fork living. Renovated in 2016 and move-in ready, this stylish waterfront retreat is designed for both entertaining and quiet moments by the sea. Inside, thoughtful upgrades include under-floor heating, ducted heating and cooling with remote access, marble countertops, updated mirrors and light fixtures, keyless entry, Sonos speakers, and a chef's kitchen. The primary suite features an egg-shaped soaking tub perfectly positioned to capture the sunset views. Outdoor living defines the property, with a huge sun deck for dining, lounging, gatherings, or yoga, plus stairs leading directly to the beach. The rare grandfathered lower waterfront platform offers an extraordinary setting at the water's edge for cocktails, Pilates, or simply taking in the Sound. The outdoor sound system extends the experience all the way to iconic Whale Rock in the water. Additional highlights include a garage with potential for conversion to 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 best.
