THE CONTROL OF URBAN BUILDING DEVELOPMENT.

The article examines the technique of the Floor Space Index (FSI) in urban building development. The technique is first applied on a considerable scale in the preparation of the plan for the reconstruction of London, England. FSI is the relationship between available floor space on a site and the site area including half the width of adjacent streets. The FSI is believed to be useful provided that the usual injunctions are observed concerning servants gaining the upper hand and becoming onerous masters. It gives the planner a summary of what accommodation the area already possesses and how much floor space one must move for the better working of the future plan. It cites that the main results of the FSI are to come when central areas are redeveloped.
