About this property

Tucked within Triton Cove, an intimate enclave of just 13 custom single-family residences, this exceptional coastal retreat at 617 Neptune Avenue delivers the privacy, tranquility, and structural confidence discerning buyers seek on Longboat Key. Ideally positioned at a quiet bend in the community and only steps from private beach access and the Gulf’s sugar-sand shoreline, this elevated concrete block home was thoughtfully designed for year-round peace of mind and storm resilience, without the burden of HOA fees. Designed by acclaimed architect Brian Phipps and built by Brista Homes in 2019, the residence offers a refined, single-level floor plan encompassing nearly 3,000 square feet of light-filled living space. Lush tropical landscaping surrounds the oversized corner lot, creating a true island sanctuary. A circular drive and double entry doors introduce interiors defined by soaring ceilings, expansive walls of glass, and clean, modern lines enhanced by elegant white tile flooring throughout. The open living and dining areas flow effortlessly to the outdoors through 10’ sliders, inviting natural light and serene garden and pool views into nearly every room. At the heart of the home, the gourmet kitchen is equally suited for everyday living and entertaining, featuring custom cabinetry with dovetail construction and soft-close hardware, striking quartzite countertops and backsplash, a center island, and a full suite of top-tier KitchenAid appliances, including an induction cooktop and double ovens. Seamless indoor-outdoor living defines the experience, with a generous covered and screened lanai overlooking a spectacular 40-foot heated pool, shell stone paver deck, and private hot-and-cold outdoor shower. The fenced yard offers additional privacy with a shell walking path and secluded seating areas, ideal for quiet reflection or intimate gatherings beneath the palms. The owner’s suite is a tranquil retreat with direct views of the pool, an oversized walk-in closet, and a spa-inspired bath featuring dual vanities, a walk-in shower, whirlpool tub, and seated makeup vanity. Two additional guest suites, each with en-suite baths, ensure comfort and privacy for family and visitors alike. Additional highlights include hurricane-impact windows and doors throughout for all-season security, a river-stone wood-burning fireplace, powder room, large laundry room with quartz counters and Electrolux washer and dryer, electric blinds, custom lighted mirrors, and an oversized two-car garage pre-wired for an EV charging station with additional parking via a separate driveway. Enjoy the rare combination of seclusion and convenience—just moments from Publix, Bayfront Park, tennis courts, leisure trails, golf, fishing, and the world-class shopping and dining of St. Armands Circle, with easy access to downtown Sarasota. Nearby deep-water marinas accommodate large yachts, completing the quintessential island lifestyle. This is a rare opportunity to own a secure, serene, single-family coastal home designed for both elegance and peace of mind in one of Longboat Key’s most exclusive, low-density communities. Schedule your private showing and experience the calm, elevated beauty of Triton Cove living.
