Along both Georgian terraces of Queens Anne’s gate, every brick window head contains an individual demonic face carved into the keystone. Cut hundred of years ago from soft bathstone, the 18 faces we were commissioned to replace had suffered beyond recognition. ASC ltd. took one silicone mould from each face and restored them in our workshop from plaster and clay. They were moulded again, then cast in more sturdy pre-cast stone for replacement and decoration.
