Presented with a new design vision by MHK Architecture, this extraordinary Captiva Island estate features concept plans to reimagine the existing residence, design a new coastal masterpiece, or expand by combining with the adjacent 1.5-acre estate lot to create a contiguous 5-acre compound unlike anything else on Captiva Island. A once-in-a-generation opportunity to own one of the islands largest and most private bayfront properties - 3.5 acres of gated serenity with an existing custom built home that has never flooded, Gulf access, resort-style amenities, and exceptional privacy along the coveted Roosevelt Channel. Surrounded by unspoiled nature, the property offers direct Gulf access with private docks. Inside, the existing home showcases soaring beamed ceilings, rich wood flooring, and a dramatic beacon tower filling the great room with natural light. Thoughtfully designed for entertaining and easy island living, it offers a chefs kitchen, formal dining, wood-accented den, private study, and flexible guest quarters. Two grand ensuite bedrooms serve as luxurious sanctuaries, complemented by an indoor wellness wing with travertine-lined pool, fitness room, and sauna. Outdoors, enjoy a tennis court, bocce court, firepit overlooking the bay, and a rooftop hot tub for starlit evenings. A three-car garage with workshop provides ample space for vehicles, storage, and all your waterfront essentials. With no HOA restrictions, the estate offers remarkable flexibility - whether envisioned as a family legacy compound, private coastal retreat, or trophy property of architectural distinction- where architectural vision meets natural beauty.
