You have it KeithG. It is part of the larger Grade 2 Grafton House in Rochester High Street, and in my day Coal Office for Hawksfield. One of my first memories as a child is being picked up from Troy Town school on a Friday, calling in there for mum to pay the coalman, then on to the market for a treat, and finally into the library; which was in a temporary structure alongside the Corn Exchange. That would probably be around 1955.
