Inside a Fire Island Home That Masters Indoor-Outdoor Living

Lucía Torres · 2026-08-12

There's something about a beach house that gets under your skin. It's not just the salty air or the sound of waves in the distance. It's the promise of a slower pace, of mornings with coffee on the deck and evenings that stretch long into the twilight. And when a home is built specifically to capture all of that, well, that's when things get really interesting. Located in the heart of Fire Island's cherished Seaview community, 35 Kelp Avenue is exactly that kind of place. It's a residence that doesn't just sit on the shoreline; it actively embraces it. With sweeping views of both the Great South Bay and the Atlantic Ocean, this home was designed for one purpose: to make every day feel like a getaway. ### A Layout That Breathes Represented by Alyssa Caravella of The Agency Fire Island, this coastal residence spans more than 3,650 square feet. That's a substantial footprint for a beach property, and every inch of it is put to good use. You'll find five bedrooms, four full baths, and two half baths, which gives everyone in your group their own space to unwind. The main level is where the magic happens. Ceilings soar to 10.5 feet in the great room, which is anchored by a fireplace and custom built-ins. Sunlight floods the space from every angle, making it feel open, airy, and endlessly welcoming. - Great room with fireplace and custom built-ins - Chef's kitchen with quartz countertops and premium appliances - Cozy den for quiet afternoons - Large screened-in porch for bug-free evenings - Guest suite, powder room, and laundry room on the first floor The kitchen flows directly into the living and dining areas, so you can cook, chat, and entertain without missing a beat. It's the kind of layout that makes hosting feel effortless, even when you've got a full house. ### The Great Outdoors, Redefined If there's one defining feature of 35 Kelp Avenue, it's the dramatic connection to the outdoors. A 16-foot wall of sliding glass doors opens the living space onto an expansive mahogany deck. This isn't just a patio; it's a full-blown outdoor living room. Under a shaded pergola, you'll find a fully equipped outdoor kitchen with a built-in grill. There's also a heated saltwater pool, which is a game-changer for those cooler evenings or early spring swims. An outdoor shower, cabana storage, and a half bath round out the deck area, so you never have to trek through the house in wet swimsuits. > This home is built around the rhythms of beach life. You wake up, step outside, and the day unfolds from there. ### Suites That Feel Like Sanctuaries Head upstairs, and you'll discover four beautifully appointed bedroom suites. Each one offers its own blend of comfort and privacy, which is essential when you're hosting family or friends for the weekend. The primary suite, though, is something else entirely. It boasts bay views, a sitting area, and dual walk-in closets. The spa-inspired bath features a soaking tub, an oversized shower, and a private water closet. It's the kind of space where you can truly decompress after a long day in the sun. ### The Ultimate Payoff At the very top of the house, a rooftop deck delivers the ultimate reward. From here, you get 360-degree views that span the Great South Bay and the Atlantic Ocean. It's the perfect spot for sunset cocktails or simply watching the sky shift colors over the water. Honestly, it's the kind of view that makes you want to slow down and savor the moment. ### Location, Location, Location Beyond the home itself, Seaview offers a tight-knit community feel. You're just minutes from popular amenities, including a playground, basketball courts, a lifeguarded bay beach, a kiddie pool, and tennis courts. Everything you need for a classic summer day is right at your fingertips. If you're ready to experience 35 Kelp Avenue in person, reach out to Alyssa Caravella to arrange a private tour.
