This space is mainly due to the conciseness and uniqueness of its geometric shape determined. This shape is gradually changing but significantly over the entire extent of the building. Its wrapping remains an uninterrupted, widely ramified surface, without this form being compromised by any other element. Accordingly, the space envelope is the only architectural element that determines this space.
It does not matter whether it is infinitely heavy and massive, or just a very thin skin. It identities itself with gravity, its mass, its weight, realises its volume, and the space that shape the displaces in the air.
