A modern architectural masterpiece on the southern end of Longboat Key, this extraordinary waterfront estate designed by renowned Sarasota architect Guy Peterson occupies nearly 3⁄4-acres in exclusive Lighthouse Point, overlooking New Pass where Sarasota Bay meets the Gulf of Mexico. Built in 2013, the elevated family compound offers 6,800 square feet of interior living, seven en-suite bedrooms, and 123 feet of waterfrontage. Walls of impact glass, striking contemporary lines, and spectacular water views define this exceptional coastal retreat. A dramatic courtyard entrance features a reflecting pool and towering glass curtain wall with exterior louvered sunscreens. Inside, soaring ceilings, beautiful hardwood accents, and expansive glass create an impressive sense of light and space. Tile flooring flows throughout the main living areas, while plush carpeting adds comfort to the bedrooms. The two-story great room opens to the pool terrace and waterfront beyond. The gourmet kitchen features leathered quartz countertops, an oversized island, custom cabinetry, and a seamless connection to the dining and entertaining spaces. Three en-suite guest bedrooms on the main level are thoughtfully arranged for privacy. An open upper-level promenade and connecting bridge overlook the great room below, leading to a spacious loft with custom built-ins, sitting areas, and a family room with morning kitchen. The private north wing houses the primary suite and an oversized guest suite suitable as a second primary retreat. Additional bedroom accommodations and multiple covered outdoor areas provide exceptional flexibility for family and guests. A detached one-bedroom casita with private entrance, bathroom, kitchenette, and bonus room offers a secluded retreat for extended stays. Outside, the heated swimming pool and spa anchor a private waterfront oasis with expansive terraces, covered dining, and a built-in grilling station. An elevated rooftop deck captures refreshing Gulf breezes, spectacular sunsets, and sweeping views of the surrounding waterways. Additional conveniences include laundry rooms on both living levels and an oversized three-car garage. A private 45-foot dock at the nearby community waterfront provides boating access to New Pass, Sarasota Bay, the Intracoastal Waterway, and the Gulf of Mexico. Within the gated Lighthouse Point enclave, residents enjoy community tennis facilities and nearby Gulf beach access. This coveted southern Longboat Key location is moments from Longboat Key Club golf and marina amenities, St. Armands Circle's boutiques and restaurants, and the beautiful beaches of Longboat and Lido Key. Downtown Sarasota's celebrated dining, theaters, galleries, and cultural attractions are also within easy reach. Combining architectural distinction, expansive living spaces, exceptional privacy, and a premier waterfront setting, 40 Lighthouse Point Drive represents a remarkable expression of contemporary coastal luxury.
