About This Home

This Seaward Homes Curated Collection residence at 6489 Gulfside is ready for occupancy. Enjoy the ultimate Longboat Key lifestyle with your own direct Gulf-front private access and stunning views of the Gulf of Mexico. Designed by DSDG Architects, this home epitomizes exceptional quality and attention to detail.

Situated on a coveted 90' Gulf/Beach-front lot, the property offers soft sands, endless Gulf views, and miles of walkability.
In 2025, Longboat Key completed a significant beach re-nourishment project, giving Gulfside Road homeowners one of the widest and deepest stretches of beach on the entire island. Equally notable, Gulfside Road is one of the rare Gulf-side streets set back from the main highway, offering a tranquil, private environment that feels worlds away from the activity of Gulf of Mexico Drive.
The main house, elevated over 15 feet, features 11' ceilings, four oversized en-suite bedrooms, and more than 6,600 sq ft of air-conditioned living space, including a grade-level, air-conditioned multipurpose room that can be tailored for wellness, fitness, or a variety of additional lifestyle needs.
The wide-open floor plan, generous room sizes, and large impact-rated safety glass sliding doors and windows fill the home with natural light. Two nearly 40' terraces on the main and second floors provide ideal spaces to enjoy the outdoor island lifestyle and breathtaking Gulf views.
Interior finishes by Studio G Homes elevate luxury living to the next level. The interior finishes include large-format porcelain tile and hardwood flooring, Italian-imported cabinetry, a custom floating steel-and-wood staircase, a three-stop elevator, 8' solid interior doors, high-efficiency mechanical systems, a top-of-the-line Thermador™ appliance package, AXOR™ and Hansgrohe™ plumbing fixtures, temperature-controlled wine storage, and detailed AV, lighting control, and security systems.
Exterior features include solid concrete and masonry construction on all floors, a deep concrete piling foundation for added strength, Longboard™ premium aluminum architectural details, and a fine light-sand exterior stucco finish. The resort-like pool area and custom spa are surrounded by a lush tropical landscape package. The garage accommodates four cars, with the option to add car lifts.
Longboat Key, an 11-mile barrier island, is just minutes from St. Armands Circle and downtown Sarasota. The Sarasota Bradenton International Airport is approximately 25 minutes away. Embrace the opportunity to own this unparalleled residence and experience the pinnacle of coastal luxury living.
