In reponse to #29 and your £30,000 will see the Heights clear of grafitti and reset a few bricks, I will remind you this image......
That sort of money will barely get professional expertise in place around the logistics of accessing the moats and how to carry out the work, before you get as far as the huge scaffold towers, materials, professional labour. This mere resetting of bricks is probably 40ft wide by 20ft hight and several courses of bricks lost
