They can always turn it into student flats!It would probably need a takeover first, because as you rightly say it s separately owned. After that I suppose it could be [theoretically] converted into [say] a store with an entrance from/into ES.
It always seems East German to me, full of empty stores. Lord knows how it makes any money. If you opened there you'd need a great break on the terms because frankly it's pretty second rate compared to ES.
