History portrays that the architecture and structure of a building have been the same for many centuries generating great constructions. However in the last decades these two concepts have been detached from each other, generating new opportunities thus affecting their relationship of integrality. In the particular case of 8111 we were motivated by the idea of testing this fusion so we proposed a diagrid type structure system, which allows the structure to be the expression of the same architecture due to the following reasons: The first is that being a system associated with diagonals and not with straight columns and beams in between slabs, it is much more demanding in the way in which structure and function must be integrated, especially so that the diagonals do not affect the flexibility of space.
