As part of the Cardiff Area Station improvement program, Seymour Harris Architecture were appointed directly by Network Rail to produce design proposals and full planning applications relative to the two main stations in Central Cardiff. Firstly the grade II listed Cardiff Central Railway Station enclosed by the river Taff, serving national destinations, and the secondly Queen Street Station located to the east of Central Cardiff adjacent the main retail areas of the city, serving local traffic.
Both projects aimed to significantly improve DDA and passenger facilities for users of the station. The process was advanced in conjunction with representatives from the Train operators Arriva, The National Assembly for Wales, and the local authority. At Cardiff Central station, a dramatic roof form was utilised to increase the presence of the station to the south of the city, and improve the relationship of the station with the surrounding public realm. In addition full height elevational glazing flooded the new passenger concourse facilities with natural day lighting. Although on a smaller scale, proposals for Cardiff Queen Street utilized a similar design language. Full permissions were received for both developments.
