Description
Virtually Staged. Brand-new custom construction in Bay Isles? This is it. Introducing an exceptional new residence in one of Longboat Key’s most coveted gated communities. Designed for effortless coastal living, this sophisticated home combines coastal contemporary architecture, elevated construction above current flood requirements, an oversized homesite, and beautifully curated tropical gardens creating a private, resort-like setting. Inside, exceptional craftsmanship is evident throughout.
The chef’s kitchen features a quartzite island, brass-strapped custom hood, panel-front refrigeration with fridge, freezer, and wine tower, vaulted beamed ceiling with concealed cove lighting and Thermador appliances. Designed to be a true masterpiece sure to impress. The great room showcases a walnut-clad fireplace wall, custom built-ins, wide-plank engineered wood floors, backlit tray ceiling, and expansive sliding glass doors opening to the outdoor living areas. The primary suite overlooking the tranquil back yard, offers a spa-inspired bath with freestanding soaking tub, rain shower, dual vanity, and customized walk-in closets. This floor plan also allows for an additional first floor primary or guest bedroom suite with custom full bath. The second floor offers three additional bedroom suites providing beautifully appointed accommodations for family and guests.
Outdoors, the home becomes its own private resort. A covered lanai opens to a heated saltwater pool and spa, beautifully landscaped backyard with its own private putting green, and stainless-steel outdoor kitchen with built-in gas grill—an exceptional setting for entertaining, relaxing, or perfecting your short game at home.
The location completes the experience. Set in south Longboat Key, the home is within walking distance of the Longboat Key Club, with golf, tennis, marina, dining, and beach club amenities nearby. Bay Isles residents also enjoy access to their own private Gulf-front Beach Club with powder-soft sand and spectacular Gulf waters. The Beach Club also provides bbq grills, pavilion, locker rooms, storage, and ice machine.
New construction, exceptional design and quality, private beach access, and one of Longboat Key’s premier locations—this home offers a rare opportunity to enjoy the Bay Isles lifestyle from day one. Close to Sarasota International Airport, downtown dining and entertainment, and everything wonderful offered by the beloved St Armands Circle.
