The Frank Lloyd Wright Home and Studio (1889/1898) served as Wright's private residence and workplace from 1889 to 1909 - the first 20 years of his career. Wright used his home as an architectural laboratory, experimenting with design concepts that contain the seeds of his architectural philosophy. Here he raised six children with his first wife, Catherine Tobin. In 1898, Wright added a studio, described by a fellow-architect as a workplace with "inspiration everywhere." In the Studio, Wright and his associates developed a new American architecture: the Prairie style, and designed 125 structures, including famous buildings such as the Robie House, the Larkin Building and Unity Temple.
