Xaveer De Geyter Architects XDGA’s proposal aims at showcasing the spatial qualities of the Rogier Square project (Brussels, BE, 2006-19) and its relationship with the underground network, by means of a large-scale model. Specifically, it focuses on the balance between two constitutive elements of the design: the patio that acts as a connector for the different vertical fluxes and the circular canopy that signals the project to the city. Both are here intended to assume an abstract, sculptural character thanks to the use of a single material (wood, painted white).
