South East. A pleasure palace condemned as a hotbed of vice, a tomb that was never used for its intended purpose, and a derelict gentleman's house: will Wiltons Music Hall in London's East End, the Darnley Mausoleum in Cobham, Kent, or Broomfield House, north London, win your vote for preservation? Restoration Secrets is at 10.30pm on BBC4, and the finalists are revealed on Thursday at 9.50pm.
