I will ask you two simple questions.
If you were a property developer wanting to build some luxary apartments and wanted those apartments to be sod or leased for profit, would you want people coming onto the site to vist a cafe, information centre and museun?
If you were a resident living on the site, would you want people visiting the above plus a theatre, hotel, pub restaurant?
The answer is NO!
As for the Orwell, the owner lost a lot of custom as a result of the museum complex closing.
I say no more as it is obvious you are a devoted servant of the Council and never see anything wrong in what Lord Smith and company do. A example being the expenses fiddle.
