One of our [his] utopian ideas is the desire to overcome the limitations of the substructure, of the earthbound. We have developed this idea in a series of proposals (sky-hooks, [like Lissitzky's paper-architecture design 'Wolkenbügel' (1924)] stadium grandstands, Paris garage]... It is the task of technology to make sure that all these elementary volumes that produce new relationships and tensions in space will be structurally safe... The idea of the conquest of the substructure, the earthbound, can be extended even further and calls for the conquest of gravity as such. It demands floating structures, a physical-dynamic architecture.
