The entrance is within the structure, penetrating the building on one side with a covered carport on the other. The carport is supported by short versions of the steel-reinforced dendriform concrete columns that appear in the Great Workroom. The low carport ceiling creates a compression of space that is released when entering the main building, where the dendriform columns rise over two stories tall; the interior space thus appears larger than it is. Compression and release of space were concepts that Wright used in many of his designs, including the playroom in his Oak Park Home and Studio, the Unity Temple in Oak Park, Illinois, the Solomon R. Guggenheim Museum in New York City, and many others.
