if you want something not fenced off you`re better looking outside of the city in small towns/villages or in the countryside

hmm... I'll have to search around, thanks.

I really wanted an old factory or something.

thanks.
heh, no not a party, for an art project.

for an art project you could contact the council and ask them they might let you use some of their property or contact any local businesses that you know hold property they are planning to renovate and ask for permission to briefly use it you never know

I'll have to look into that, thank you.
