Could be the facade is listed or demolition not been finished ?. Theirs a pub on West Street,Sheffield called the Hallamshire Hotel but goes by another name the lower tiled section is listed but the rest of the building could be demolished would be a challenge for a developer . Some years back on Fargate theirs a listed Victorian building but only the front part was listed they pulled down the rest while they put around the protected part a metal frame to hold it up . Was a odd sight.
