The modern development borders the south side of Shepherd's Bush Green and was designed in the 1960s.

Originally constructed with a rooftop car park and a connecting bridge to the station (decorated with an Inter-City railway train mural), West 12 was significantly redeveloped in the 1990s.

The bridge was removed, and the centre now houses several chain stores, a 12-screen Vue cinema, gym, pub, restaurants, a Bush Doctors and a Lidl supermarket (formerly a Presto, then Safeway followed by Morrisons).

The hotel opened in the summer of 2012[3][4] In August 2017 it was announced that Lidl would replace Morrisons which shut in late 2016.

As of November 2023, tenants of West 12 include Sainsbury’s, Boots, Card Factory, CeX, Holland & Barrett, JD Sports, Lidl, Poundland and Vue Cinemas.
