The foyer has been "cleaned up" and has got a new color design. On a white base, the walls of the foyer were marked through a stencile to provide new accents of colour and content. The stencile refers to the shape of the tube. This is a large piece of furniture that can be used for performances. The tube has wheels and can be placed anywhere in the foyer. It was designed so that you can take it apart in two pieces and can be transported outside. Chairs, sofas and tables can be stored in the tube. All furniture is constructed of fiberglass in B1-flame resistant.
The tube is an organizing element. It can be used as a space and stage for the youth theater project "Treibhaus". This project deals with the areas of adolescents in the private-(children's bedroom), semi-public (youth club) and the public environment (city). The scenographies take place in the theater foyer.
