The building comes up close to the crown of plane trees – this is the first thickness to act as a filter from the street. The facade serves as an unfurling ribbon that works as a backdrop to the different universes contained in the programme. At its closest to the street, the ribbon dips, the better to contain it, rising again where it stands further back. In the hollows, the border between the interior space and the urban space is less clear and makes it possible to come closer, to embrace the building visually. The hollow and solid sections produce an ambiguity between inside and outside, questioning the borders of the public space.
