Frank Lloyd Wright Home and Studio
Frank Lloyd Wright Home and Studio in Oak Park, Illinois.
This is the side of the house facing Chicago Ave, where his clients would come from. Wright designed the entrance in such a manner that it would take some thinking on behalf of the client to actually locate the door! By doing so he filtered out his clients, those that gave up and left he didn't care to work with anyway while those that persisted would meet his approval.
Today the Frank Lloyd Wright Home and Studio is owned by a trust that maintains it and runs guided tours of the home and studio.
