An exceptional offering in Marco Islands prestigious Estate section, this canal-front residence encompasses over 6.000 square feet of living space on an oversized 125-by-175-foot homesite. Designed for the discerning waterfront buyer, the property boasts two boat lifts—one 35,000 pounds for a 40-foot vessel— and a 20,000 pounds, adding an extra level of boating enjoyment, direct Gulf access and a dedicated fish cleaning station. The interiors blend architectural grandeur with livability. Expansive windows and high-impact doors throughout the home invite natural light and frame water views while providing enhanced security and storm resilience. Every room reflects exquisite attention to detail—from soaring ceilings, breathtaking cupola, and fine finishes to refined millwork and custom built-ins. The primary suite is a private sanctuary, offering a sitting room, wet bar, spa-inspired bath and a dedicated fitness room. Upstairs, a second guest suite features a loft and a private lanai with panoramic views of the water and city skyline. Formal living and dining rooms are paired with a great room featuring a fireplace and bar, while the chefs kitchen—equipped with a gas range and walk-in pantry—delivers efficiency and function. A private theater/media room, complete with wet bar, fireplace and guest bath, provides a luxe space for entertaining. Outdoor amenities rival private resorts, including a pool, spa, pool bath, fireplace, full summer kitchen and a bonus rooftop capturing sweeping vistas. Additional appointments include a top-notch Sonos surround sound system, Savant home automation, a 30,000-watt generator with 1,000-gallon propane tank and a three-car garage. A new tile roof was completed in 2025 and the seawall dates to 2003. This residence offers a rare combination of coastal access, architectural integrity and elevated design in one of Marco Islands exclusive enclaves. Adjacent lot set up as tropical beach site also for sale separately. Paradise living at its finest.
