Not the best image of Costa Coffee at the Prudential Assurance Building on Pinstone Street, Sheffield. However, late night is the best time to explore the city. Behind the rubbish lies a story. When this was built in 1896 the doorway was the entrance to Birds Hotel, the shop front on its right forming part of the restaurant. It lasted about twelve months before Prudential Assurance booted William Bird out for not paying his rent. Here is the interesting part. The window to the left is actually the original entrance to the ground floor Prudential Assurance office, as architect Alfred Waterhouse designed it, later reconfigured and moved around the corner.
