Great photos and having travelled along Yardley Road over many years , I'm certain that the building with the archway is on the site of the builder's yard. Looking back over previous posts, it seems the City Estates Officer made some attempt to find a user for the old building before seeking demolition approval. The Government's response states that no objections were made to the demolition proposal. What we don't know is how widely the application was advertised. Or perhaps we were not as vigilant or concerned about the loss of our heritage 50 years ago.
