Blur Building

A pavilion with no walls, no façade and nothing to look at — a walk-in cloud of lake water and fog, built for one Swiss summer in 2002.

Architecture made of weather

Blur was the media pavilion of Expo.02, the sixth Swiss national exhibition, held across four towns on the three lakes of the region in 2002. The commission dated to 1998, and the project cost is put at about 7.5 million dollars — a serious budget for a building designed to have no visible substance at all. Moored off Yverdon-les-Bains in Lake Neuchâtel, its structure was a lightweight tensegrity platform — roughly 91 by 61 metres, rising about 23 metres — held above the water on four columns standing on piles driven into the lake bed. The structure had no envelope at all. In its place: water, pumped from the lake, filtered, and forced through some 35,000 high-pressure nozzles as a mist of droplets a few microns wide. The building was the cloud that mist made.

A smart fog

The fog was not a special effect sprayed at constant pressure. A computerised weather system continuously read temperature, humidity, wind speed and wind direction, and adjusted the nozzles so the cloud held a coherent form against the conditions — swelling, thinning and drifting, but never quite dispersing. Visitors crossed two footbridges from the shore and walked into white noise: visibility dropped to almost nothing, sound blurred into the roar of the nozzles — a soundscape the artist Christian Marclay contributed recordings to — and other people appeared as ghosts a few steps away. At the top sat the Angel Deck, a viewing platform above the cloud (an earlier scheme for a bar serving waters from around the world was cut along the way). The architects described the result as formless, featureless and massless — a media pavilion that erased media, a spectacle with nothing to see. Swiss critics were not confused for long: Blur was named best building of 2002 in Swiss TV and B. magazine’s Golden Rabbit awards.

Gone by winter

Yverdon-les-Bains hoped to keep Blur as a permanent science-fiction museum, but the money and the will were not there. Within six months of the exhibition closing, the pavilion was dismantled and its steel recycled. Nothing has stood on that part of the lake since the end of 2002, which is why the project survives mainly as photographs, a book — Blur: The Making of Nothing — and profiles like this one.
