First opened as a temporary timber structure, the current station building was designed by Welch & Lander in an Art Deco/Streamline Moderne style influenced by the Underground's principal architect Charles Holden. The station buildings are formed from a series of simple interconnecting geometric shapes. Plain red brick masses are accented with strong horizontal and vertical glazed elements. A large circular ticket hall with high level windows gives access to the platform stairs. The enclosures for these form cascades of glazed steps down to the platforms.
