[9] Nearby landmarks include Beaversfield Park, Hounslow Medical Centre and St. Paul's Church.

[note 4] Works were completed on 27 November 1926, with the station's alignment reconfigured to have three platforms and brought into use on 11 December.

[17] Piccadilly line services, which had been running as far as Northfields since 9 January 1933, were extended to Hounslow West on 13 March 1933.

Formal approval was given in 1967,[21] and work began with a groundbreaking ceremony by Sir Desmond Plummer on 27 April 1971.

The line surfaces briefly over the River Crane before descending to reach Hatton Cross towards Heathrow.

[25] Platform 3, being the northernmost, was decommissioned early on 22 October 1971 due to being situated right on the path of the new track alignment.

[8] The new building is in a style reminiscent of Holden's designs for the 1926 Morden extension of the City and South London Railway (now part of the Northern line).

Glazed screens are fitted onto all sides of the tall heptagonal ticket hall, with an adjoined rectangular shopfront.

[8] In addition to its drum shape being heptagonal, its ceiling motif contains this pattern, with a chandelier featuring seven lamps of the same geometry.

[31] The building is very similar to the reconstructed station at Ealing Common built at the same time, also by Heaps and Holden.

[34][35][36] The platforms are reached by flights of stairs and a stairlift,[37] which makes the station step-free for manual wheelchair users only.

The proposals also include a new public square, retail space and a smaller amount of replacement station car parking.

Notably, the A1 express service picked up passengers from the station, but this ceased when the Heathrow extension opened in 1977.

[23] Winston Churchill recalls travelling to Hounslow Barracks two or three times a week whilst living at his mother's house in Knightsbridge around 1896.
