Drawings on walls & unwanted post


There is a rectangular shape that has been drawn on the wall of the southcore building on the ground floor next to the lift. Please could people respect the fact that this is our home and we all want to live in a nice clean place. Things like this really do make this beautiful block look dirty and discusting. Also could people refrain from throwing their unwanted post on the floor, there are bins in the courtyard for rubbish… Thanks
