The shell of the paint shop contains the production plant leaving the more interesting zones visible. The form of the building is determined by the functionality of the operation carried out on the first floor, the service areas on the ground floor and the facilities provided for the visitor flow. To allow observation of the more interesting phase of the paint cycle, a gallery has been constructed high above the factory floor, reached by ramps and stairways. On the southwest corner of the building, a multi-storey greenhouse provides connections between floors and houses the energy production plants.
