The council chamber is a multifunctional hall: it is a wedding venue as well as a council chamber and is used every year as the venue for the ceremonial surrender of the keys at the start of the Carnival feast. Of course, this is also where council meetings take place. The chamber therefore requires a flexible interior which can be used in many different ways. In addition, an extensive audiovisual system has been installed, enabling the council meetings to be live-streamed. The sanitary facilities have been modernised and amenities such as pantries and storage have been added.

A special rug has been designed for the chamber, inspired by the council archive of prints and the Gennep skyline. Even the storks who nest on top of the chimney have been incorporated. Yellow and red are the colours of Gennep.

The council chamber has been rendered sustainable, whilst taking into account the monumental character of the space. The windows have been provided with secondary glazing, LED lighting has been installed and the chamber has been fitted with a sustainable air treatment installation which has been carefully integrated into the monument.
