Tower Blocks: Love Them or Loathe Them?' was the debate at the Museum of London, as an exhibition on the subject opened there. 'They look good in the sunset from Primrose Hill,' said Ronan Point-demolisher Sam Webb, before reeling off a list of their failings. 'If they were economic, Barratts would be building them everywhere,' he concluded. Others - Martin Pawley, Miles Glendinning, and long-time Trellick Tower resident Lee Boland - were more positive. But the outrageous remark of the evening came from the Bartlett's Iain Borden: 'I'm speaking as a historian so my view is balanced,' he announced.
