A Legacy Home Steeped in Craftsmanship

Built in 2005, Serenissima spans 19,300 square feet of interior living space across three grand levels, perched on a 1.18-acre beachfront lot. From the moment you step inside the soaring marble entry hall, crowned by a hand-crafted glass dome, the residence commands attention with its Venetian-inspired artistry. Featuring six lavish bedrooms and eight spa-caliber bathrooms, the home was designed as a sanctuary for those who appreciate timeless craftsmanship and bespoke details.

Inside, nearly every surface pays homage to old-world splendor. The grand salon is a spectacular entertaining space capable of hosting over 100 guests, while the adjacent sunroom is a tranquil retreat facing the sea. Drenched in natural light, the interiors are adorned with Venetian murals, custom millwork, and glittering chandeliers that reflect generations of European design tradition.

In a conversation with Luxury Houses Magazine, listing agent Rich Polese of Compass Florida LLC described the property as “an extraordinary blend of scale, soul, and serenity. The Longboat Key real estate is massive in size, but every corner invites intimacy. It’s not just an estate – it’s a masterwork.”

Refined Luxury Behind Every Door

845 Longboat Club Rd is defined not only by its artistry but by the carefully planned lifestyle it affords. The gourmet chef’s kitchen features expansive custom cabinetry, a double island setup, breakfast bar, and top-tier appliances designed to support both everyday living and formal hosting. The home theater, with seating for ten, offers a cinematic experience framed by deep wood tones and plush velvet textures. Meanwhile, the sunroom, flooded with light and panoramic sea views, acts as a transition between the grand salon and the terrace, overlooking the pool and private beach.

Moreover, in this Longboat Key home for sale, two spacious primary bedroom suites each feature oversized walk-in closets and opulent ensuite baths, while guest suites on the second and third levels provide both privacy and Gulf views. The home’s den and office spaces offer ideal nooks for remote work, reading, or quiet retreat. Even the utility rooms and elevators carry forward the property’s commitment to bespoke elegance.

Perhaps most astonishing is the 12-car garage of this home in Longboat Key for sale, described by Mr. Polese as “not a parking space, but a gallery – a collector’s dream in every sense.” Car enthusiasts will find generous room and refined finishes even in this utilitarian area.

Gulfside Grandeur Meets Outdoor Serenity

Outdoors, the coastal lifestyle unfolds with unmatched beauty. The saltwater infinity pool, heated spa, and wraparound terraces provide sweeping views of the Gulf of Mexico, just steps from a deeded stretch of white-sand beach. Mature landscaping adds privacy without obstructing the ocean vistas. Sunsets viewed from the terrace are nothing short of cinematic, coloring the sky in hues that mirror the Longboat Key real estate’s rich interiors.

Serenissima’s exterior design includes several covered porches and balconies, offering flexible options for dining, lounging, or entertaining alfresco. The manicured lawn leads directly to the Gulf, making morning beachcombing, paddleboarding, or sailing not just activities, but daily rituals.

Longboat Key’s Premier Lifestyle

Beyond the gates of Regent Court, residents of this Longboat Key home for sale enjoy the amenities of the Longboat Key Club – one of Florida’s most prestigious resort-style communities. Membership includes access to championship golf courses, top-tier tennis courts, a luxury spa and fitness center, marina services, and several waterfront dining options.

The surrounding Longboat Key area is prized not just for its exclusivity, but for its accessibility. Within a 10-minute drive is St. Armands Circle, a charming destination for upscale shopping and fine dining. The cultural heart of downtown Sarasota – with its opera house, symphony, ballet, and galleries – is less than 25 minutes away. World-class healthcare at Sarasota Memorial and private aviation services at SRQ Airport complete the lifestyle proposition for discerning buyers.

In an exclusive quote to Luxury Houses Magazine, Rich Polese shared, “What makes Serenissima even more compelling is that it’s turnkey for a buyer who values privacy, artistry, and community all in one. The location, the home, the craftsmanship – everything here is once-in-a-generation.”

A History of Distinction

The story of 845 Longboat Club Rd reflects a history of careful ownership and rising value. This Longboat Key real estate last sold in 1998 for $2.15 million, before undergoing a complete, multi-year custom build. It was later listed for $26.5 million in 2017, and after a series of adjustments, sold in 2020 for $16.5 million. Its current listing at $35 million reflects not only market growth, but the continued rarity of luxury estate architectural icons in Florida.

While Luxury Houses attempted to reach the current owners for comment, the family declined an interview, choosing instead to let the legacy of the estate speak for itself. This discretion is emblematic of the lifestyle Serenissima offers – refined, serene, and shielded from the spotlight.
