This began as a terrific book of the same name by Stewart Brand, who investigated why some buildings grow and change and adapt to the lives of the people who inhabit them, while others simply don't meet their inhabitants' needs. He's adapted these ideas for this 6 part BBC video series. Anybody involved in designing a new building or adapting an existing one would benefit from the book and this series.
The site includes a video clip of selected sections of the video series.
