This contemporary masterpiece captures the relaxed spirit of beachfront living through clean lines, organic textures, and a crisp, minimalist aesthetic to create a space that feels airy, bright, and deeply connected to nature. Interior layouts embrace high ceilings and massive open-plan living zones share light across the entire footprint through vast expanses of glass. The distinctive 6,660-square-foot beach house blends strict structural engineering with minimalist design to celebrate the coastal environment so proudly on display. Luxury finishes and fixtures are accented with 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 encompass nearly 1,200 square feet of beautiful open living, enhanced by a dramatic two-story ceiling and seamless access to the oversized lanai. Multiple sets of triple glass sliders open wide to dissolve the boundaries between indoors and out, 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, integrated Sub-Zero refrigerator and freezer, and two Sub-Zero beverage refrigerators. Elevated to showcase the 180-degree unobstructed views of the horizon, a glamorous primary suite gives an exquisite bath surrounded in plush comfort amenities where gorgeous vistas dominate the space. Two additional ensuite bedrooms, a dedicated office with bath, and a loft library with a lengthy 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 parking access to your vehicle and water toy collection, 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 items all through the house include 5 full bathrooms and laundry room both with marble counters and flooring, water filtration system and softener, a Generac generator, an alarm system with ten cameras, and Sonos audio system. Outdoor living is an integral part of this exceptional beachside residence, with multiple levels designed to capture breathtaking water panoramas and embrace the beauty of the surroundings. Spanning the entire Gulf-facing façade, a covered ground-level patio, second-level lanai, and 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 designed to embrace everything that makes Florida living so extraordinary.
