The main block, fronting Bridge Street, was designed by James Miller in early French Renaissance style. The massive four-storey and attic building was built with cream sandstone. There was an arched entrance to a central booking hall at street level and additional entrances leading directly to the platforms at each end of the building, at 40 and 52 Bridge Street. These side entrances are still in use as access to apartments following the redevelopment of the upper levels of the block for residential use in 1994. The station buildings are now protected as a category B listed building.
