Tucked into the natural landscape of Grassy Key, 235 Tropical Avenue offers a unique combination of space, privacy and the unhurried character that defines life in the Middle Keys. Set on a 15,000-square-foot lot in Crains Subdivision, this concrete stilted residence offers more than 3,600 square feet of living space, impact windows and doors, and generous indoor-outdoor areas designed around the Florida Keys lifestyle. An expansive open layout creates room to gather, entertain and settle in comfortably, with multiple living spaces and an easy connection to the outdoors. Lush native vegetation surrounds the property, creating a remarkable sense of privacy and seclusion. The partially fenced backyard centers around an inviting in-ground pool with waterfall, tanning shelf and water features, setting the stage for long afternoons outside and evenings under the palms. Ample parking provides room for multiple vehicles and boat trailers, an especially valuable feature for enjoying life on the water. Above it all, a rooftop observation deck captures ocean views and a beautiful perspective across Grassy Key. Watch the light change over the horizon and native birds gather around the natural salt ponds behind the property. Crains Subdivision also offers a community sunset park, while a public boat ramp is just minutes away for convenient access to the surrounding waters. Centrally positioned between Marathon, Duck Key and Islamorada.
