An initial gesture – a folded plane – was transformed into an element that shapes this convergence space. From a site with two facades, this structural element announces, on one hand, the creation of a space inside the building, and on the other, an opening toward the public space of the historic center of Santa Fe. The fold and the space thus become a transition device between architecture and the city. There is a first limit, precise and forceful, a lid that reconstitutes the urban scale, which contains what happens from that point onwards, an autonomous microclimate from its forms, a succession of draining spaces.
