Arlington House, a 61-year-old tower block in the seaside town, had been the subject of looming plans to modernise its windows, replacing them with bulky new structures which had spooked residents and heritage campaigners alike.But Thanet District Council voted unanimously to reject the proposals, following a snowballing social media campaign led by Emin and backed by hundreds of people.Emin, who owns a flat in the 18-storey block, said that some of her faith in humanity had been restored following the decision.AdvertisementPosting on her Instagram account, she wrote: A loud cheer was heard in the Margate council chamber. For me personally it was such a relief. The decision restored some of my faith back into humanity.The Turner Prize nominee had described the proposed new windows as bulky and unsuitable, insisting they would spoil the clear, beautiful views from the seafront building.
