Encompassing 546 acres with 375 acres designated as a nature preserve, Key Marco offers spectacular panoramic water views, access to luxury facilities, and unmatched privacy for its residents. This oversized .63-acre homesite offers approximately .30 acres of uplands and .33 acres of wetlands, creating a lush natural setting and buffer around your future custom home. Design a 3000 square foot or larger residence that rises into the landscape, with the potential for up to 55 feet above the first floor grade, subject to applicable approvals, capturing elevated views across serene waterways, native preserve and toward the Gulf. Here, your home will feel immersed in nature rather than surrounded by neighboring rooftops. Key Marco offers lush landscaping and exceptional privacy while remaining just minutes from Marco Island's beaches, dining and everyday conveniences. Owners enjoy access to the community marina with direct (no bridges) boating access to the Gulf, along with clubhouse amenities, fitness facilities, tennis, pickleball, fishing areas and scenic paths.

Rarely does a Marco Island homesite offer this combination of privacy, natural beauty, boating access and the freedom to create something truly distinctive.
