More Than 200 Projects are included in the Archigram Archival Project. The AAP uses the group’s mainly chronological numbering system and includes everything given an Archigram project number. This comprises projects done by members before they met, the Archigram magazines (grouped together at no. 100), the projects done by Archigram as a group between 1961 and 1974, and some later projects.
The Montreal Tower was a project commissioned by Taylor Woodrow and executed at the Euston office. It was presented to the authorities of the (then) forthcoming Montreal Expo as a "central feature". It had to incorporate a central concrete tower and provide a wide variety of public entertainment functions. This brief was extended to form a "skin and guts" proposition: a vertical tree with enormous roots on to which could be hung temporary exhibition elements that would be removed and replaced after the Expo.
In many ways, the project served as a trial run for notions of structural and component replacement that were developed in the Plug-in City. By comparison, the structure of the tower is closer, and the lift tubes -- though diagonal -- still form a separate structure. A skin wraps around the whole of the temporary infill.
