The book is written by a non-architect. Stuart Brand is a person who thinks clearly about our future, and therefore is in a good position to comment on the future life of architecture. He makes the very simple argument that buildings have a life beyond their immediate completion, and that architects should design their buildings acknowledging that. The standard architectural approach to adaptable buildings changing is to use lots of gizmos: sliding doors, folding screens and so on. Brand’s thesis is different – although he does talk about the technical stuff, his view is that adapting buildings is more of a social endeavour.
