Set on the north end of Siesta Key, this striking modernist residence offers the rare balance of island serenity and seamless access to the mainland, placing vibrant downtown Sarasota, Southside Village, and the area's cultural and dining destinations just minutes away—while the azure waters of the Gulf of Mexico and Siesta Key's world-famous white quartz sand beach are equally close at hand. Designed with crisp architectural lines and a light-filled, contemporary aesthetic, this nearly 3,800-square-foot, four-bedroom, four-bath home redefines modern coastal living. An open floor plan, 12-foot ceilings, and expansive walls of impact-resistant glass windows and doors create a natural flow throughout the home, blurring the line between indoors and out while capturing the relaxed elegance of island life. A dramatic natural rosewood floating staircase serves as a sculptural centerpiece, leading to the main living level where modern design and functionality converge. The living area is anchored by a 100-inch electric floating wall and linear fireplace, creating a striking focal point for both everyday living and entertaining. Modern LED lighting, thoughtfully integrated throughout the interior and exterior, enhances the home's clean lines and architectural presence. The open-concept kitchen is sleek and refined, featuring premium appliances, a natural gas cooktop, contemporary cabinetry, and generous prep and gathering space—ideal for entertaining or relaxed daily living. The primary suite is a tranquil retreat, highlighted by a spa-inspired bath with LED, anti-fog mirrors, a 74-inch soaking tub, and a walk-in closet, along with direct access to outdoor living. Three additional guest suites are thoughtfully designed to offer comfort, privacy, and flexibility, each with designer finishes and modern baths. One of the home's most distinctive features is the private balcony with a spa-style hot tub —perfectly positioned for morning relaxation, evening unwinding, or enjoying coastal breezes after a day at the beach. The property also offers ample room to add a pool, allowing future customization of the outdoor living environment. Elevated and thoughtfully constructed in accordance with current building guidelines, the residence offers peace of mind without compromising style. Beneath the home, an exceptionally expansive garage and storage level can accommodate 12 or more vehicles, a rare and highly sought-after amenity on Siesta Key. This level also includes a separate flex room with an overhead door that opens directly to the backyard, making it ideal for a private home gym, wellness studio, hobby space, or additional entertaining area. Just a short stroll away, a charming neighborhood beach at Big Pass provides a front-row seat to boats gliding through the pass and colorful sunsets each evening, a favorite local spot that perfectly captures the laid-back beauty and maritime energy of the north end of Siesta Key.
