The complex of residences and offices rises where the headquarters of the British secret services were located. The design of the complex is born from the gaps left by the demolition of the pre-existing building, so a 22-faced jagged polyhedron is drawn. The space was complex for the geometry of the urban fabric, and so there was a combination of changing façades, each different in height, orientation, color, and relationship with light. The mass is so lightened and fragmented, composed of so many pieces of different colors connected to each other. The facades stop from 4 to 6 meters from the ground, making the site accessible and transparent, an invitation to converge into the inner square where shops and public activities are concentrated.
