Privately positioned on a tropical peninsula on Siesta Key in the coveted community of Hidden Harbor, this extraordinary bayfront estate captures sweeping views across Sarasota Bay, the Intracoastal Waterway and the downtown Sarasota skyline. Set on .62 acre with 125 feet of panoramic waterfront, the residence was masterfully built by luxury builder M. L. Collingwood and thoughtfully designed to celebrate both architectural craftsmanship and the beauty of its remarkable setting. A protected deep-water harbor, private 50-foot dock and 20,000-pound lift create an exceptional opportunity for the serious boater, while the home's privacy, scale and resort-style outdoor living make it equally ideal as a serene waterfront retreat. From the moment you arrive, custom mahogany doors, beveled glass transoms, lush landscaping and a gracious entry introduce the timeless character found throughout the residence. Inside, soaring ceilings, generous room proportions and walls of glass frame magnificent water views from many of the principal living areas. Rich architectural details include coffered and tray ceilings, bentwood arches, crown molding, custom millwork and travertine inset flooring. The formal living and dining rooms flow beautifully for entertaining and are complemented by a fully outfitted cherrywood-paneled bar and wine room. The executive office and library is a showpiece, featuring cherrywood paneling, an 18-foot coffered ceiling and a spiral staircase leading to upper bookshelves. The well-appointed island kitchen offers Wood-Mode cabinetry, quartzite countertops, stainless steel appliances, paneled Sub-Zero refrigeration, a Viking six-burner gas range, dual ovens, a walk-in pantry and a spacious breakfast bar. Open to the bayfront breakfast and gathering rooms, the space features an electric fireplace, adding warmth and ambiance and connects effortlessly to the outdoor living areas. The primary suite is a private waterfront sanctuary with a bayfront sitting room and a generous bath with dual vanities, a two-person shower, soaking tub and private water closets. Two additional guest suites are privately positioned in their own wing on the main level, along with a powder bath and laundry room. Upstairs, a fourth bedroom or game room includes a full bath, walk-in closet and private western balcony overlooking the harbor, ideal for taking in evening sunsets. Designed for relaxed Florida living, the expansive lanai features a heated saltwater infinity-edge pool, travertine decking and a shaded outdoor living space with custom ceiling detail, creating an inviting setting for alfresco dining and waterfront entertaining. Frequent dolphin and manatee sightings add to the magic of this rare waterfront setting. Additional features include a side-entry three-car garage, paver drive and walkways, landscape lighting, walk-in attic and abundant storage. Hidden Harbor is one of Siesta Key's most treasured boating communities, offering exceptional privacy just one mile from the powdery white sands of Siesta Beach and close to Siesta Village's dining, shopping and island charm. Mainland Sarasota's cultural venues, restaurants, shopping, medical facilities and schools, including nationally acclaimed Pine View School, are also within easy reach.
