Work started in 1865, and in 1867 a barrel roof enclosed the station designed by the Metropolitan Railway's engineer Sir John Fowler.

The station was further redeveloped under the plans of the Metropolitan Railway's consultant architect, George Campbell Sherrin, between 1906 and 1907.

[10][11] Sherrin's designs saw the barrel roof taken off with the platforms covered by plain wooden shelters on iron columns.

The North end of the platforms saw a new superstructure built over them, which contained a new octagonal booking hall, and an arcade that led to the High Street.

[10][12][13][14] The octagonal booking hall was rebuilt by London Transport in 1937-38 to increase its capacity.
