The original model for this project was made by Warren Chalk and Ron Herron in 1963 based on Ron's elevation and axonometric drawings and Warren's pan. It then was photographed to be used as illustrations in the catalogue for Living City exhibition which was included in the second issue of Living Arts magazine.

The model was made simple materials – various sizes of wooden rods and dowels which were then wrapped in aluminium foil (kitchen baking foil).

The model was never shown in exhibition and was very soon lost or destroyed.

The facsimile of the original model was made in 1993 to accompany the traveling exhibition ARCHIGRAM – Experimental Architecture 1962–1974, using the same materials.
