The Elthorne Works project comprises housing and offices on an under-used industrial site on Trumpers Way, Hanwell, in the London Borough of Ealing.
Designed by Patel Taylor Architects, the scheme includes 205 apartments in three buildings above a podium of eight townhouses.
Commercial elements include industrial units on the ground floor.
Hossein Abedinzadeh, founder of MHA London, said: “I am immensely proud of this project which has not forgotten the site’s industrial past. It is important to us that all our projects are not only commercially successful but provide a positive contribution to the neighbourhood.”
