This major refurbishment of this Northern Line Underground Station involved alterations to the ticket hall, lower concourse and platform, as well as the installation of cable and communication systems to cater for improved passenger security and information needs.

As a listed building, the station walls, floor and ceiling finishes were restored to their original condition.

Excavation and construction of two new tunnels was undertaken, 25 metres below street level. These excavations required a temporary shaft, 2.5 metres diameter, to be excavated from street level requiring a major traffic management system.

Working hours were restricted, mainly occurring during the night, hence, keeping noise and dust to a minimum was essential. The quality of the refurbishment has been recognised, by the Ian Allan National Railway Heritage Certificate of Excellence Award.
