In 2015, Cardinal’s storage hall was rehabilitated as a workplace. No fewer than 126 prefabricated containers made from local timber have been installed on three levels. The industrial hall’s façades have been covered with polycarbonate to bring natural light into the interior spaces and to harmonise the building exterior. Large skylights have been installed in the roof, providing additional natural light. To meet the site’s environmental criteria, the container and workshop areas are heated by an air-water heat pump, powered by 1,800 m² of photovoltaic panels on the roof.
