The Atrium is our largest space and suitable for multiple purposes.
It has a built-in sound system and wireless microphones, which can be used for talks/presentations, live musical performances, or the playing of recorded music.
It has a seating capacity of ca. 100 persons.
It has a standing and maximum capacity of ca. 200 persons.

Room size – 16.2m x 11.7m


The Bar Room is directly off the atrium. It can provide a smaller space for smaller gatherings or can be used in combination with the atrium to create more space and allow for the accommodation of more people. The bar room has a large white wall that can be used as a screen for projecting slideshows or films, in combination with a beamer/projector. It also has a physical bar complete with three refrigerators, bar sink, glassware, serving trays, etc. It does not have any beer taps and COS does not provide any drinks.

The seating capacity of the Bar is ca. 45 people
The standing capacity is ca. 60 people

The tables can also be removed from the bar to allow for theater/lecture style seating (chairs in rows). The tables can also be replaced with our high-top standing tables, which allows for more standing room.

Room size – 13.4m x 5.95m

For use in Atrium and Bar:
19 Tables – 80cm x 80cm – seat 4
9 Tables – 1.6m x 80 – seat 6
9 high top standing tables
ca. 120 Chairs

We have a professional, electric piano available for use.

*Currently, we do not, in principle, rent out the Bar and the Atrium separately. This is due to the fact that these rooms are not able to be booked/occupied at the same time by two different parties. If you have any questions about this, please phone us or send us an email.
