Christ & Gantenbein, in collaboration with Johnston Marklee for museography and interior design, and Rapp Architekten, won an international competition to update and renovate one of the most recognized museums of its kind: The Hauptbau, the main building of the Kunstmuseum Basel, built in 1936.

The common goal is to preserve the museum's cherished atmosphere and enhance the museum’s porosity through new programming and select interventions inside, and to propose outdoor spaces, in plazas and gardens, that further advance the museum into the civic realm, enhancing the institution's exchange and active communication with urban life.
