Book available on amazon Published on: 2010-05-04 Original language: English Binding: Paperback 180 pages This book explores the appearance and impact of cycles in urban surroundings and, in a second stage, their potential for an urban proposition. Examples can be found in time, economics, environment or social activities. Cycles appear through a wide range of scales and often without referring to them. Investigating these patterns in a spatio-social context makes sense regarding urban planning and urban sustainability as well as from a theoretical point of view in the sense of a spatial-temporal concept. The first part, is designed as an observational study in an existing urban environment, the second part, is an application of some of the findings to a proposal for a floating city in the Thames Estuary.
