In November 2003 the station was voted the second biggest "eyesore" in the UK by readers of Country Life magazine. This might be blamed on the sub-surface nature of the station and the 1960s architecture. New Street was voted joint worst station for customer satisfaction with Liverpool Lime Street and East Croydon, with only 52% satisfied; the national average was 60%.
That all changed when a £550m redevelopment of the station named Gateway Plus opened in September 2015. It includes a new concourse, a new exterior facade, and a new entrance on Stephenson Street.
Also, a nice bit of leg synchronicity going on (which might be linked to renewed customer satisfaction)
