Main issues, as the Inspector framed them

  • Whether the proposed works and development would preserve the Grade II listed building known as '49 Thornhill Road (No 49)' and any of the features of special architectural or historic interest that it possesses
  • Whether the proposed works and development would preserve or enhance the character or appearance of the Barnsbury Conservation Area
  • Whether the proposed works and development would preserve the setting, as it relates to the special interest of the nearby listed buildings known as '35 and 37 Belitha Villas', 'Numbers 27 and 29 and railings attached to number 27', 'Numbers 31 and 33 and attached railings' and '51 Thornhill Road'

What decided it

The proposal would cause moderate less than substantial harm to the special interest of the Grade II listed building through loss of historic fabric, windows, layout and features, which is not outweighed by the public benefits and fails to satisfy the requirements of the Planning (Listed Buildings and Conservation Areas) Act 1990 and the heritage protection aims of the National Planning Policy Framework.
