Built in 1787 and last renovated in the 1980s, the theatre presents a grand classical façade towards Koblenz's Deinhardplatz. Behind the scenes, however, is a different story: over the years, the complex was extended a number of times, and today many of the theatre’s functional areas – offices, dressing rooms, rehearsal rooms, workshops, lounges – are housed in several outbuildings connected to the historic theatre. A substantial part of these operational spaces are located on Clemensstraße. This building does not make the theatre visible to the outside world as an important modern cultural institution, and does not provide adequate working conditions for the theatre’s staff.

Large windows are opened in the ground floor to allow passers-by a glimpse of the activities inside, while the existing façade of the building is replaced by recycled aluminium panels, as a reference to the materials used backstage in a theatre. The different functions of each space are indicated by the variety of aluminium profiles, with each different pattern or orientation of the panels’ folds representing a different part of the building’s programme. In addition to coloured blinds, large, brightly lit letters are placed on the façade to further communicate the purpose of the building.
