Capacity
The venue publishes a maximum of 180 seated, 250 standing reception, 180 theatre style. Those are top figures for an empty room. A dance floor, a stage, a buffet or a photo booth each take space, so plan on fewer guests than the maximum once your layout is drawn.
A useful rule: a seated dinner at rounds of ten needs about 1 to 1.2 square metres per guest, a standing reception about 0.7, and theatre seating about 0.6, before you add a stage or dance floor. The venue capacity calculator does the arithmetic for your room.
Events it hosts
According to its own event pages, the venue hosts corporate events, weddings and private social events.
