To illustrate the Smithsons disapproval for modern urban design a quote from Peter Smithson after he visited in 1954 the new suburbs of Amsterdam, the Netherlands.
'It is nothing more or less than a great filing system for men, based on the assumption that shelter and food alone have to be provided. […] People have descriped to me how Van Eesteren thinks of the city as a living Schwitters, a great developing mutating organism. Unfortunaly the bus tickets in this case happen to be three storey flat blocks; a pattern which seems incapable of providing any sort of framework for live.'
