Book excerpt: This is a digitally reprinted edition of Urban Space and Structures, first published in 1972. This first volume in the Cambridge Urban and Architectural Studies series is a compilation outlining the growth of a particular line of research work which was taking place at the Centre for Land Use and Built Form Studies in Cambridge at the time. It attempted to understand some of the factors which, at a theoretical level, condition the range of choices that are available, whether in a building, the nodal point in a city or the complete urban system.
