One-of-a-Kind Gulf-Front Luxury at Ten35 Seaside! Welcome to Unit #503—an extraordinary, custom-designed Gulf-front residence on South Siesta Key. Thoughtfully reimagined with over $400, 000 in bespoke upgrades, this one-of-a-kind home delivers a level of luxury, craftsmanship, and exclusivity rarely offered.

From the moment you arrive, convenience meets prestige with two deeded parking spaces and one of only eleven private storage lockers in the building. Inside, a reconfigured layout maximizes sweeping, unobstructed Gulf views, while curated finishes include exquisite precious stone slabs, advanced AV and home automation, and custom acoustic paneling for a truly immersive living experience.

The chef’s kitchen is a showpiece, featuring a backlit precious stone backsplash, premium appliances, and custom cabinetry designed for both beauty and performance. An adjacent wet bar—complete with custom shelving, a full-size Sub-Zero wine refrigerator, and beverage cooler—sets the stage for effortless entertaining.

The Gulf-front primary suite is a serene retreat with panoramic views, a spacious walk-in closet, and a spa-inspired en-suite bath with dual vanities and an expansive walk-in shower. Three additional guest suites provide luxurious comfort and privacy for family and guests alike.

Outdoor living is equally impressive, with a generous Gulf-front terrace and custom outdoor kitchen, ideal for alfresco dining while taking in the sights and sounds of the shoreline.

Residents of Ten35 Seaside enjoy a resort-style lifestyle with beach attendants, a Gulf-front pool, fire pits and grilling areas, a state-of-the-art fitness center, on-site property management, and an optional on-site rental program offering income potential.

A rare offering at one of Siesta Key’s most coveted addresses, Unit #503 represents the pinnacle of Gulf-front living—where exceptional design, unparalleled customization, and breathtaking views come together. This is more than a residence; it’s a coastal masterpiece.
