Parameters you need to take into consideration:
Who owns the space? How does this influence your legal form?
How does urban zoning regulation affect the activities you would like to implement? Is this reflected in your organisation legal form?
Take care of necessary permits to understand if the space is ready to be opened or rather if it should be improved: check your local and national technical specifications and requirements related to practical settings such as fire protection, alarm systems, number of emergency exits, accessibility.
