Pepys Estate

Wiki: "The estate is made up of several 4 storey blocks, ten 8 storey blocks and three of London's tallest tower blocks at 24 storeys tall. The 8 storey blocks have a strange internal arrangement in that from the front door to each flat, you either go up or down a short flight of steps, and the floors are on three split levels. With the exception of the 24 storey towers, the blocks are built of red brick. When completed, the estate won a Civic Trust design award."

Which just goes to show how meaningless these architectural awards are. Because the buildings are very ugly and were later discovered to be intrinsically flawed. Quite apart from the fact that local people were refusing to live in them.
