Designed by Elizabeth Diller and Ricardo Scofidio, the Blur Building, also called The
Cloud, is a media pavilion for the Swiss Expo 2002 in Yverdon-les-Bains, a small spa
town at the southern end of Lake Neuchâtel in the west of Switzerland. Located in the
lake, close to the water’s edge, the Blur Building sprays 5000 litres of filtered lake
water a minute through 31400 nozzles to form an artificial cloud, 100m long, 60m
wide and 20m high, hovering above the lake. A weather station within the building
controls water vapour output in response to climatic changes that affect the size and
form of the cloud, such as humidity, air temperature, wind speed and direction. Diller
Before leaving the land, each visitor completes a character profile, which is stored
electronically in a hooded ‘intelligent’ white raincoat. The raincoat provides protection
from the wet environment and communicates with the Blur Building’s computer
system. Visitors reach the Blur Building via two 100m long ramped glass-fibre bridges.
As the visitor moves towards the cloud the experience becomes progressively white.
