Process

The existing 1970s building forms a large, sprawling volume on a sloping site.

The cruciform complex fragments the outdoor space. In their 1989 competition design, Herzog & de Meuron remedy this by adding blocks to form inner courtyards.

The old design envisaged four airy glass structures.

Tactile details: turned doorknob, silicone door handles, table legs, tentacle-like lamps.

By day, the office buildings seem to merge with the park, while at night they shine out like huge lanterns.

Separate and open-plan spaces, a canteen renovated in 1970s style and works by Thomas Ruff add distinctive touches.
