Ferdinand Fellner:

We were never primarily concerned with creating works of architecture with these auditoria, but rather endeavoured to develop the space to be functional and attractive, and to present the audience, the best and finest decoration of each auditorium, to its best advantage; it was only at this stage that we attempted to give this basic setting an architectural design

Quoted from Götz, Thomas: ‘Die Theatermacher’, in: Parnass 16 (1996)
