Perched atop the coveted South Building at L’Ambiance behind the gates of the Longboat Key Club, this extraordinary beach-to-bay penthouse redefines luxury coastal living. Encompassing nearly 5,000 square feet of refined interior space and complemented by more than 3,600 square feet of wraparound terraces, this rare residence offers the scale and privacy of a waterfront estate paired with the convenience and security of one of Longboat Key’s most prestigious condominium communities. From sunrise over Sarasota Bay to spectacular sunsets melting into the Gulf of Mexico, panoramic water views create a breathtaking backdrop from nearly every room. Arrive via a private elevator that opens directly into your own grand foyer, where ornate wrought-iron double doors reveal a residence defined by architectural elegance and meticulous craftsmanship. Cathedral coffered ceilings, intricate millwork, crown molding, custom built-ins, designer lighting, and expansive walls of newer impact glass create a dramatic yet inviting atmosphere throughout. Travertine flooring flows seamlessly from room to room, while floor-to-ceiling glass sliders open to expansive terraces, blending indoor and outdoor living on an unprecedented scale. At the heart of the residence, the impressive 34-by-41-foot living room is framed by Gulf views and surrounded by multiple entertaining spaces, including formal and informal dining areas designed for both intimate gatherings and grand-scale events. The gourmet chef’s kitchen is beautifully appointed with custom designer cabinetry, stone countertops, decorative appliance panels, a Wolf induction cooktop, oversized island, walk-in pantry, and generous workspace for effortless entertaining. Occupying its own private wing, the primary suite is a sanctuary. A private vestibule leads to a spacious lounge area, dual walk-in closets, and spa-inspired his-and-her bathrooms featuring custom vanities, stone finishes, soaking tub, separate shower, and abundant storage. Floor-to-ceiling glass opens directly to the terrace, where sweeping Gulf views create an ever-changing panorama. Two additional guest suites offer en-suite baths and walk-in closets, while a fourth bedroom—currently configured as a charming bunkroom—provides flexibility for family and guests. A spacious study can easily serve as a fifth sleeping area or executive home office. The outdoor living experience is simply unmatched. Expansive terraces wrap around the residence, creating multiple venues for dining, entertaining, and relaxation while capturing unobstructed views stretching from the Gulf shoreline across Sarasota Bay, the Longboat Key Club golf courses, and the downtown Sarasota skyline. L’Ambiance is widely regarded as one of Longboat Key’s premier beachfront addresses, offering residents exceptional amenities including 24-hour gated security, concierge services, on-site management, a recently renovated lobby and clubhouse, social rooms, fitness center, tennis courts, resort-style heated swimming pool and spa, private beach access, and a picturesque boardwalk leading directly to the Gulf of Mexico. Ideally positioned within the Longboat Key Club community, residents enjoy proximity to championship golf, tennis, marina facilities, waterfront dining, and miles of pristine Gulf beaches.

Value check
Is the price right?
The internet’s favorite home-value number comes from a single automated model that has never seen the street, the finishes, or the view — which is why it routinely misses by tens of thousands of dollars. The edgeAI estimate combines multiple independent data sources with our team’s on-the-ground expertise in this exact market.
