It was in fact this narrow driveway which was the key to the project. How to make the building impressive and commanding when the main bulk of the building is 10m set back. The tube seemed a natural way to bring the building to the street. But because 5 cars had to be parked on the site the tube had to be suspended and cantilevered as supporting columns would have made the drive way to narrow.

The 20m long tube is attached to the building for 10m of its length - it then cantilevers out the next 10m unsupported!
