Tucked into Fire Island’s beloved Seaview enclave, 35 Kelp Avenue has been designed for effortless indoor-outdoor living and elevated entertaining, all set to sweeping views of the Great South Bay and Atlantic Ocean.

Represented by Alyssa Caravella of The Agency Fire Island, this 3,650-plus-square-foot coastal residence encompasses five bedrooms, four full baths and two half baths. Sun-filled and open, the main level rises to 10.5-foot ceilings in a great room anchored by a fireplace and custom built-ins.

The chef’s kitchen, outfitted with quartz countertops and premium appliances, flows directly into the living and dining areas, while a cozy den, large screened-in porch, guest suite, powder room and laundry room round out the first floor.

35 Kelp Avenue’s defining feature is its dramatic connection to the outdoors. A 16-foot wall of sliding glass doors extends the living space onto an expansive mahogany deck, where a shaded pergola, fully equipped outdoor kitchen with built-in grill and a heated saltwater pool create a true backyard oasis. An outdoor shower, cabana storage and a half bath complete the main deck area. This layout is built around the rhythms of beach life.

Upstairs, four beautifully appointed bedroom suites offer comfort and privacy for family and guests. The primary suite is a destination unto itself, boasting bay views, a sitting area, dual walk-in closets and a spa-inspired bath with a soaking tub, oversized shower and private water closet.

At the top of the house, a rooftop deck delivers the ultimate payoff with 360-degree views spanning the Great South Bay and the Atlantic Ocean, ideal for sunset cocktails or watching the sky shift over the water.

Located just minutes from Seaview’s popular community amenities, including a playground, basketball courts, lifeguarded bay beach, a kiddie pool and tennis courts.
