That skin is made of prefabricated modules, soft green, set in front of the existing building. The module is the project’s unit: it is drawn once, in elevation and axonometric, and its repetition makes the façade. Pivoting sashes allow opening without breaking the rhythm. At night that rhythm turns over: the façade goes dark and it is the lit rooms that draw the grid.
