The original station building was cramped and unable to cope with peak demand during matches at the nearby Lord's Cricket Ground.

It was demolished and reconstructed in 1924–25, to a design by the MR's architect Charles W. Clark, with a larger building that enclosed the space above the platforms with a concrete slab to form a parking garage under the original glazed platform roof.

[2] In the mid-1930s the Metropolitan line was suffering congestion at the south end of its main route, where trains from its many branches shared the limited capacity between Finchley Road and Baker Street.

It had been the intention of the Underground's management to close Lord's station to normal services, but retain it for temporary use during top-class cricket matches; the advent of the Second World War led this plan to be abandoned, and the station closed permanently after the last train on 19 November 1939.

An emergency access point existed as of 2004 [5][6][7] and a stairwell went to a piece of the platform remaining at the trackside as a result of it.
