Enjoying an exceptional 270 ft of L shaped water frontage facing the 185 ft wide Pines Canal and the natural beauty of Bill Baggs Cape Florida State Park, this elegant island coastal estate is tailored to a boating lifestyle. Offering a calm and naturally sheltered harbor, a concrete seawall, boat lift, dockside kitchen, and side dock boat storage that preserves unobstructed water views, the property provides a sense of openness, privacy, and tranquility. Clean architectural lines, an internal garden courtyard, and generous covered terraces fill the residence with natural light and create a seamless connection to the surrounding water and landscape. This elevated home offers four bedrooms plus staff quarters, five bathrooms, and four half baths within 7,996 adjusted square feet of interior space on a 16,500 square foot lot. Architectural tray ceilings, refined millwork, custom wall paneling, and thoughtfully designed built ins with abundant storage add depth and craftsmanship while maintaining a light, contemporary coastal aesthetic. Formal living and dining rooms with elegant millwork provide an ideal setting for entertaining. The kitchen is appointed with Calacatta Gold marble countertops, gas cooking, Sub Zero and Viking appliances, and a butlers pantry. Additional highlights include two family rooms, a fitness center with water views, two garages accommodating seven or more cars or golf carts, a temperature controlled wine cellar for approximately 1,400 bottles, an elevator, retractable screen doors, a generator, and a saltwater heated pool.
