Heritage Information Cockfosters station Listed as a building of National Significance Architect: Charles Holden, 1933 The station opened in the then small hamlet of Cockfosters on 31 July 1933, the last of the stations on the extension of the line from Finsbury Park. The station was to be a focal point for a new suburb and although some development took place, areas to the north and east of the station became part of the protected London Green Belt. The station building is a low European style brick structure flanked by two small towers each with a pole mounted roundel. The alignment of road and rail approaches was developed to produce a ticket hall concourse of pentagonal plan. Reinforced concrete was used for the entire concourse and train shed. At the time, the use of such materials, unadorned, was viewed as a modernistic approach to buildings in this country. The station is located in a 'cutting' and required natural light to enter from above, so the roof was built in two levels with inclined celestory (sic) windows run-in the full length terminating in an apex above the concourse. Other noteworthy elements of the station include the predominant use of bronze framed signs and windows, the original passimeter, rectangular train describer box with integral clock and the timber seats. This station, along with adjoining stations on the Piccadilly line, are now internationally recognised as being some of the finest examples of 1930's architecture designed by Holden and Partners. The station was grade II listed in May 1987.

Chiswick Park station Listed as a building of National Significance Architect: Charles Holden, 1933 The station first opened on 1 July 1879 by the Metroploitan District Railway when the railway was extended from Turnham Green to Ealing Broadway. The station was originally named 'Acton Green' and was renamed to 'Chiswick Park' on 1 March 1910. The original station was demolished in 1931 to accommodate the new Piccadilly line tracks, although the Piccadilly line has never served this station, and the new building opened in 1933. The new station was designed by Charles Holden in a modern European style using brick, reinforced concrete and glass. Similar to the station at Arnos Grove that Holden designed for the eastern Piccadilly line extension, the station's predominant feature is the tall semi-circular ticket hall. Externally the brick walls of the ticket hall are punctuated with panels of clerestory windows and the structure is capped with a flat concrete slab roof. To make the station's location visible from Chiswick High Road the station was also provided with a square brick tower surmounted by the roundel and the stations name. The ticket hall once housed a central passimeter, whcih has now been replaced with the brick built ticket office accommodation which has altered the appearance of the grandiose hall. The station was Grade II listed on 18 February 1987.

Northfields Station Architect: Charles Holden & Partners, 1932 The first station opened here in 1905, on the District line, but the present building was constructed as part of the 1930's extension of the Piccadilly line that helped fuel the suburban growth of this once rural part of London. Holden's impressive building takes the form of a single storey plinth, which contains offices and shops, and is faced in black glazed brick. The tall brick box that forms the ticket hall has a window that includes the Underground roundel. The design continues down to platform level, where extensive use is made of concrete, which at the time was a novel concept.
