Mireille Roobaert captures the symbolic CBR building situated in Watermael-Boitsfort in Brussels, a brutalist piece of architecture designed by architects Constantin Brodzki and Marcel Lambrichs. Its prefabricated modular facade showcases white concrete instead of hiding it as a construction material, experimenting with unusual organic shapes. Every material, detail and finishing in the building was chosen by the architects themselves, even the buttons on the elevator.

In November 2018, it was added to the list of protected heritage within the Brussels Capital Region.
