Ardmore has landed the deal to build a new student development on the site of a former perfume factory in west London.
The contractor confirmed it had been picked by Imperial College to build a series of residential blocks in Acton.
The blocks will range from nine to 31 storeys and will comprise 603 studio and twin-bed units, as well as a 10-storey PRS block.
A total of 600 student rooms and 85 PRS residential units will be delivered within the buildings.
Imperial bought half of the former Elizabeth Arden perfume factory site off Essential Living in February 2017 in a deal worth £30m.
It is the second high-profile London scheme Ardmore has landed this year after it won the £77m deal to build The Gantry, a new 18-storey hotel development in Stratford.
Ardmore managing director Cormac Byrne said: “I am especially pleased that Imperial College have shown such confidence in us to deliver one of their most prestigious schemes.
“140 Wales Farm Road will be the tallest traditional masonry tower in the UK, and its unique design provides several challenges – not least providing external façade access at 31 storeys via an innovative climbing screen.”
