Workshops between Navy's tidal basin and dry dock [c.1907-c.1975]
The building is easy to spot, with high ceilings and a row of pitched roofs. It was built during the extension of the naval yard c.1907:
Most of the naval yard's buildings were demolished soon after the dockyard closed in 1959, but the workshops lasted longer. They're shown at the top-left corner of this 1960s photo.
I guess they were demolished in the 1970s to make way for the Prince of Wales building that was built on this site.
