The new station was constructed by Taylor Woodrow Construction to a design by London Midland Region architects of British Railways, William Robert Headley and Ray Moorcroft, in consultation with Richard Seifert & Partners. Redevelopment began in summer 1962 and progressed from east to west, including the demolition of the Great Hall, while a temporary building housed ticket offices and essential facilities. The project was planned to keep Euston working to 80% capacity during the works, with at least 11 platforms in operation at any time. While services were diverted elsewhere where practical, the station remained operational throughout the works.
