Green's stations had been two-storey structures; the lift plant housed in part of the first floor level behind the characteristic semi-circular arched windows.

This featured mosaic tiled Underground roundels over the entrances similar to those installed at Maida Vale station.

[4] Four of the stations (Brent, Colindale, Hendon Central and Edgware) were given stone colonnaded frontages somewhat reminiscent of cricket pavilions.

[5] Hendon Central station was quickly surrounded by and incorporated into a larger block of shops and apartments so that the simple elegant building can no longer be easily discerned.

He worked throughout that period with the Underground's consultant architect, Charles Holden, on a number of stations including Hounslow West and Ealing Common.
