The book 'The Space Between' is the third part of the intended collected works of Alison and Peter Smithson and complementary to the volumes 'The Charged Void: Architecture' and 'The Charged Void: Urbanism'. While the Charged Void books deal with the built and unbuilt projects realized over the years provided with short comments, The Space between is a text book architects richly illustrated, mostly with drawings and photographs by the Smithsons themselves. It can be considered as a summary of their thinking as architects since the beginning of their career, mainly trying to grasp the identity of places by observations of daily life, developing what they liked to call 'a sensibility of place'.
