Le Corbusier, The City of Tomorrow and Its Planning, 1929

For business: sky-scrapers sixty storeys high with no internal wells or courtyards. Residential buildings with "set-backs", of six double storeys; again with no internal wells: the flats looking on either side on co immense parks. Residential buildings on the "cellular" principle, with "hanging gardens," looking on to immense parks; again no internal wells. These are "service-flats" of the most modern kind.
