Nearly Complete New Construction on Siesta Key! Just steps from the sugar-white sands of Siesta Key Beach and a short stroll to Siesta Village, 646 Calle del Otono offers an exceptional opportunity to own a brand-new coastal estate nearing completion in one of Sarasota’s most walkable, high-demand locations. Designed with both style and function in mind, this expansive residence will feature eight bedrooms and eight-and-a-half bathrooms, thoughtfully laid out across multiple levels to create space, privacy, and flow. Soaring ceilings, natural light, and high-end finishes are planned throughout, blending relaxed island aesthetics with refined craftsmanship. At the heart of the home, a chef-inspired kitchen will include premium appliances, a large central island, custom cabinetry, and wine refrigeration—ideal for both casual family meals and elevated entertaining. The main living space flows effortlessly to the outdoors, where plans include a private heated pool and spa, multiple covered terraces, and a custom outdoor shower—perfect for rinsing off after the beach. One of the home’s standout features is the rooftop deck, offering rare panoramic views of the Gulf of Mexico—an elevated space ideal for sunrise coffee, sunset cocktails, or stargazing above the treetops. Each of the seven king suites is designed as a private retreat with en-suite bathrooms and upscale finishes, while a custom bunk suite adds flexible accommodations for families or guests. A private elevator, ample storage, and a carefully considered layout round out the home's exceptional design. With completion just around the corner, this is a rare chance to secure a nearly finished, new construction estate in a premier Siesta Key location—where modern luxury meets the ease of island life.
