You can renovate a house. You can't recreate the land. At the end of Sunrise Lane, on a 28,500 SF peninsula with water on three sides, sits one of the most compelling residential sites in Key West. 3750 Sunrise Lane combines land, privacy, waterfront, and scale in a way that simply does not come to market. This is not just a residence. It is the chance to build a significant Key West waterfront estate around the one thing that cannot be improved upon: the setting. Originally built in the 1950s and extensively expanded and rebuilt in 1999, the 5,378 SF residence offers five bedrooms and four and a half baths with heart pine floors, French doors, abundant natural light, and wide waterfront terraces. Three bedrooms and a spacious primary suite are on the first floor, while two upstairs guest bedrooms open to a covered balcony and rare widow's walk with sweeping water and protected land views. An expansive family-style kitchen and breakfast room anchors the home, complemented by a den with built-in wet bar and a separate studio and flex room offering multiple possibilities. Outside, the true scale of the property reveals itself. More than 3,200 SF of brick patios surround the large pool and tropical landscaping. Over 500 linear feet of seawall provides protected dockage, two boat lifts, and immediate deep-water access to the Atlantic and Gulf. A finished 828 SF, four-door garage completes this exceptional waterfront property. The residence is offered as a restoration and reimagination opportunity. It carries deferred maintenance, and with it the freedom to shape the property's next chapter rather than inherit someone else's. Restore its character. Rethink its spaces. Create a waterfront compound worthy of the site. 28,500 SF of land. Water on three sides. More than 500 feet of seawall. Protected dockage. Direct access to the Atlantic and Gulf. Homes can be transformed. Land like this cannot be recreated.
