Be renewed and inspired by this striking Gulf-front residence in an exclusive island community, featuring an impressive 100 feet of direct beachfront. Renovated and redesigned in 2025 to offer seamless indoor-outdoor integration and wide, unobstructed Gulf views, the setting is simply spectacular. This sophisticated contemporary masterpiece captures the relaxed spirit of beachfront living through clean lines, organic textures, and a crisp, minimalist aesthetic, creating a space that feels airy, bright, and deeply connected to nature. Interior layouts embrace high ceilings and expansive open-plan living zones that share light across the entire footprint through vast expanses of glass. The distinctive 6,660-square-foot beach house blends rigorous structural engineering with minimalist design to celebrate the coastal environment. Luxury finishes and fixtures include Louis XIV champagne White Oak floors, Dennis & Leen custom chandeliers and sconces, and a custom Murano glass chandelier. The living room, dining room, and kitchen span nearly 1,200 square feet of open living, enhanced by a dramatic two-story ceiling and seamless access to the oversized lanai. Multiple sets of triple-glazed sliders open wide, dissolving the boundaries between indoors and out and creating a dramatic setting for effortless entertaining, relaxed gatherings, and unforgettable open-air living. In addition to mesmerizing tropical views and a light-drenched workspace, the extraordinary kitchen and butler's pantry feature marble counters and high-end appliances, including a Wolf double-range oven, a Wolf steam oven, an integrated Sub-Zero refrigerator and freezer, and two Sub-Zero beverage refrigerators. Elevated to showcase the 180-degree unobstructed horizon views, a glamorous primary suite offers an exquisite bath surrounded by plush comfort amenities, with gorgeous vistas dominating the space. Two additional en-suite bedrooms, a third bedroom currently used as an office with a bath, and a loft library with a long wall of built-in bookcases offer plenty of room for everyone to unwind and rejuvenate at day's end. The ground-floor space has 2 garage doors for vehicle and water-toy access, an elevator to the second and third levels, a huge lounge with abundant seating, a large-screen TV, an adjoining exercise room, and 2 mini-split air conditioners dedicated to this enormous ground-level space. Notable features throughout the house include 5 full bathrooms, a laundry room with marble counters and flooring, a water filtration system and softener, a Generac generator, a security system with ten cameras, and a Sonos audio system. Outdoor living is integral to this exceptional beachside residence, with multiple levels designed to capture breathtaking water panoramas and embrace the surrounding beauty. Spanning the entire Gulf-facing façade, a covered ground-level patio, a second-level lanai, and a third-level balcony create an effortless progression of spaces for relaxing, entertaining, and enjoying spectacular sunsets. A truly exceptional beachside retreat, 6529 Gulfside Road delivers a refined coastal experience that embraces everything that makes Florida living so extraordinary. From its spectacular setting to its thoughtfully designed spaces, every element celebrates the beauty, ease, and allure of Gulfside living. *Variance in place and plans drawn for 1,000 sq. ft. guest house and pool, making the square footage over 7,500 under air.
