Wingspread is the house Frank Lloyd Wright designed for HF Johnson Jr, one of the SC Johnson company's leaders. It is the last and largest of Wright's Prairie-style abodes, completed in 1939. It's enormous, with 500 windows and a 30ft-high chimney. Free tours through the building take one hour, and must be booked in advance. The home is about 5 miles north of downtown Racine.
