Capacity
The venue publishes a maximum of 300 seated, 350 standing reception. 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 weddings, corporate events, galas and fundraisers, holiday parties and private social events.

Planning entertainment here
Heritage estates often have strict rules about rigging and open flame. Strolling performers, string trios and close-up magic suit the rooms well.
Send every performer’s technical needs to the venue before you book: floor space, ceiling height, power, sound and changing room.

Check the venue website for directions, parking rates and accessible entrances, and send the details to guests with the invitation.
