Frank Lloyd Wright’s Spring House, Florida

NTFHP/Krystyn Pecora

Designed by Frank Lloyd Wright in 1954, the Spring House (aka George Lewis House) is the only private residence in the state constructed by the famed architect. There are more than 400 intact Wright houses around the country, however, only a few are left that feature the unusual "hemicycle" structure. The home's design was so significant, it was placed on the National Register of Historic Places in 1979, just 25 years after construction. Today, it is in need of major repairs due to weather damage and old age.
