I dare say that whoever rents the place is obliged by the landlord to keep the place in good order. Hence the eventual re-glazing. What if, this time, after the windows are replaced they board-out each arched window space and had the 'yoof' adorn them with some festive scenes? Not a lot of use seems to be made of them at present in any case.
This whole thing may be emblematic of the wider UK economic scene. Smash what you have got, shore-up here and there with a hope of replacement eventually. The policies of George 7 Dave writ small.

Ignorance is bliss, bliss is happiness, I am happy...to draw your attention to the possible connectivity in the foregoing.
