About this home

This Key Colony Beach half-duplex offers the kind of everyday simplicity that defines life in the Keys. Two bedrooms, two baths, and a comfortable interior layout provide a solid foundation��perfectly workable today, with opportunities to elevate the space when you're ready. Vaulted ceilings run throughout the home, creating a sense of openness and inviting in natural light. Set along a 100-foot wide canal with 37.5 feet of dockage, the property offers an easy connection to the water and the island lifestyle. The outdoor space is where the property shines: an expansive, fully fenced yard with a tiki hut already in place and more than enough room to add a pool or create extended gathering areas. It's an open setting that feels made for unwinding, gathering, and enjoying the Keys at an unhurried pace. If you've been looking for a home with generous outdoor space, convenient boating access, and the freedom to shape it to your style, this one offers exceptional value and a welcoming canvas in a community loved for its island charm and walkable amenities.
