From the planning drawings it looks like the audience area is approximately 20m x 25m so 500m2.It was actually 1300 standing mate. Not a huge difference but we are as well getting it right. Extract of the ‘blurb’ is posted earlier in the thread for reference.
At an approximate ratio of 2.5 people per m2 the 1300 capacity seems ok. I don't know what is legally allowed for a standing concert but I have been at gigs where it seems to have been more than this.
The bar looks to be about 8-10 m long (hard to tell from the plans) but I would guess this would be about OK.
I am sure the servicing areas (kitchen facilities, bar etc.) have all been mapped and are all of the correct size, layout etc. to be able to cater for the numbers required depending on the type of function.
I guess the toilet facilities are again, what is legally required for the amount of people who could be using them.
It may not appear to be big enough, but I think it will be fine, but i guess it depends on what peoples expectations are.
