By 1938, Wright was already 71, LIFE magazine had featured him on their cover, and the Fallingwater House for Mr. Kaufmann was being completed in Pennsylvania – he was at the peak of his career.

For the “dream house” project, LIFE magazine commissioned Frank Lloyd Wright with a design for the Blackburn family in Minneapolis, who had a yearly income of $5.000 to $6.000. The house he designed was Usonian by all means. He defined the Blackburn house as a “little private club with special privacies, ultra conveniences and style all the while.”

The house featured a swimming pool outside, while inside the open plan combined the living and common recreational area into one big space. Wright designed a free and flexible space for a modern family.
