ADU Design in Key West, FL

The southernmost city in the continental U.S., Key West is an island chain city built on tourism, hospitality, and the military — home to Naval Air Station Key West, a dense Old Town historic district, and a cruise-ship port. Extreme hurricane exposure, corrosive salt air, and some of the lowest land elevations in Florida define every project.
