ABSTRACT
Human architecture would no doubt be different if we could fly freely in three dimen-sions. Because we walk and are held down by gravity our lives mainly take place on flat surfaces and our architecture is concerned with the planning of floors. With this limitation in movement, human life and architecture tend to deal primarily with the two horizontal dimensions. Architects tend to accept and sometimes even celebrate this emphasis by designing buildings in which movement and places are organised between horizontal planes of platform and roof.
