Architecture and Design for the Family in Britain, 1900-1970''; by David Jeremiah (2000) Notable schemes included a proposal in 1955 to demolish the entire area of Soho and rebuild it entirely in glass; a 1957 proposal for the replacement of St Giles Circus in London with a 150 feet tall glass heliport; and the 1963 "Crystal Span" proposal for the replacement of London's Vauxhall Bridge with a seven-story glass building straddling the River Thames, which was to have contained a shopping mall, luxury hotel, residential development and a museum to house the modern art collection now housed at Tate Modern.
