The carriage shed, now without direct connection to the DC line, between Stonebridge Park station and Stonebridge Park LU depot was originally built to house LNWR stock using the DC line.

The current station platforms and associated buildings were first built by the London, Midland and Scottish Railway in 1948 to a design attributed to John Weeks[10] following destruction of the original structures by bombing in World War II, the booking hall at ground level appears to be the original building.

The platform-level style of the rebuilding was different from that of the original DC line stations (but not the same as the 1938 South Kenton station on the same line), utilising concrete and steel rather than brick buildings with wood and glass canopies.

London Underground's Stonebridge Park Depot is 500 m (550 yd) to the north-west of the station.

The Brent Viaduct, a Grade II listed building built by the London and Birmingham Railway in the 1830s, is immediately south of the station.
