The roof and platforms of the 1900 – 1922 station were designed by J. W. Jacomb-Hood and A. W. Szlumper, engineers for the LSWR.
The roof is of transverse ridge and furrow construction and is 520ft by 540ft.
The maximum single span is about 118ft.
The office buildings were designed by J. R. Scott, the chief assistant architect for LSWR. It is in Imperial Baroque style and is notable for its Victory Arch. This was designed to commemorate the loss of LSWR servicemen during the First World War. It is constructed from Portland stone and carries statues depicting War and Peace, which are placed below a statue of Britannia.
