Mécanique Céleste is the project of a new entrance for the University of Engineering and Management of Canton Vaud in Switzerland. A&F Architectes intervene on the campus with a structure-sculpture easily identifiable from the outside and to which the terraces of heig-vd are connected through new paths.

The architectural construction is based on a geometrical concept: the circle in which the courtyard of the Aula was inscribed — the space alongside the new extension — has been moved and has subsequently created a new space, the external foyer, and a new curved wall built in concrete, in continuity with the existing structure.

Propped by caissons recalling the interior of the Pantheon dome in Rome, this 9-meters-high structure offers an optical illusion effect, the anamorphosis, when observed from the access door. The blue colour used in the space becomes a disk inscribed in a square, bringing the architecture to a two-dimensional level.
