The land in big cities has be used more intensively, but the possibilities are limited. One of the leading options for the future is the use of the flat roofs of residential buildings and office blocks as a building site.

This book analyses and describes the opportunities for realizing projects of this kind, as well as the potential difficulties, using interesting examples of construction on top of existing buildings in the Netherlands and abroad. It will therefore be influential in establishing a benchmark for architecture and urban planning that is a necessity if rooftop architecture is to have a serious future.
