The Cloud is an organism for living. Designed by Coop Himmelb(l)au in 1968, although the project was fully detailed, it remained in 'project' status.

The structure is mobile, the space can be modified. The building materials are air and dynamics. The Cloud places emphasis on technique as a means to an end but not an end in itself. Architecture is content, not shell.

The Cloud was designed for the study "Living forms for the future" and was planned as a realization for the Documenta V. It was thoroughly developed down to the smallest detail in terms of concrete form and structure.
