Apparently some fuckers intervened to prevent the owner from altering the exterior by having it listed despite being less than twenty years old at the time.
In the United Kingdom, a listed building, or listed structure, is one that has been placed on one of the four statutory lists maintained by Historic England in England, Historic Environment Scotland in Scotland, Cadw in Wales, and the Northern Ireland Environment Agency in Northern Ireland... A listed building may not be demolished, extended, or altered without special permission from the local planning authority.
For anyone else who is interested, the first is the Mappin & Webb building. The latter is No 1 Poultry.
