During the Second World War, the lower floor of the clubhouse was also used as an Air Raid Precautions centre, and one of the dressing rooms was the map room. On 20 December 1947, the largest ever attendance for an international test at Odsal was set when 42,685 saw England defeat New Zealand 25–9. The first floodlit rugby match in the North of England was held at Odsal in 1951. In September 1951, Council Engineer Ernest Wardley drew up a plan for a 92,000 capacity 'European' style stadium, at a cost of £250,000. Eventually £50,000 was spent on terracing the Rooley Avenue end in 1964, before the Wardley plan was officially dropped the following year.
