About this home

Enjoying an exceptional 270ft of L-shaped water frontage facing 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 calm and naturally sheltered harbor, 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 4 bedrooms plus staff quarters, 5 bathrooms, and 4 half-baths within 8,240 sqft of living space on a 16,500-sqft 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 butler’s pantry. Additional highlights include 2 family rooms, fitness center with water views, 2 garages accommodating 7+ cars/golf carts, temperature-controlled wine cellar for 1,400+ bottles, elevator, retractable screen doors, generator and saltwater heated pool.
