The station originally had entrances in single-storey pavilions with stone-effect stucco render on each side of Euston Road with stairs to the platforms.

Ventilation shafts lined with glazed white tiling were spaced along the platforms to let in light from openings in the front gardens of the houses at street level.

[14] LCR branches would have connected from east of Gower Street to Euston and St Pancras stations.

[16][17] In 1906, the original timber platforms were reconstructed in concrete as a fire precaution related to the electrification of the MR.[18] The station was given its present name on 1 November 1909.

[20] At the same time the station platforms were lengthened requiring the closure of Euston Road to enable the roadway and tunnels to be excavated as quickly as possible.

In the 21st century, the buildings on the south side of Euston Road were again redeveloped and the station entrance was again reconstructed.

This will create a direct link for users of main line rail services which depart from Euston.

[23] The station is served by the Metropolitan, Hammersmith & City and Circle lines, between King's Cross St Pancras to the east and Great Portland Street to the west.
