The new station was designed by Kenneth J. Davies, lead planner for British Rail London Midland Region. Twelve through platforms replaced the eight through and six bay platforms of the previous station. The platforms were covered over by a concrete deck, supported by 200 columns, upon which the concourse and other buildings were constructed. Escalators, stairs and lifts were provided to reach the platforms from the concourse. The new station had sold its air rights, leading to the construction of the Pallasades Shopping Centre (then known as the Birmingham Shopping Centre) above the station between 1968 and 1970. The public right of way across the station, which had previously been maintained by the station footbridge, was retained in the new station via a winding route through the shopping centre. The station and the Pallasades were partly integrated with the Bullring Shopping Centre via elevated walkways above Smallbrook Queensway.
