Hadley Property Group has submitted plans to deliver a major new retrofit neighbourhood at the former GSK headquarters in Brentford.
The company’s proposals for the transformation of 980 Great West Road will see more than 2,300 homes and more than 330,000 sq ft of commercial space built on a 13-acre site.
The new homes will comprise a mix of tenures including build-to-rent, co-living and purpose-built student accommodation, 35% of which will be affordable.
Two key buildings from the original campus, including the high-rise tower, will be retained and adapted, with their reuse being integral to the overall low-carbon approach to the redevelopment of the site.
The new neighbourhood is grounded in a reuse-first strategy and utilising this approach across both the existing building and basement will save more than 50% of the site’s embodied carbon footprint.
More than 60% of the site has also been given over to public realm, including play areas, gardens and riverside access. The commercial space will include 30,000 sq ft of workspace designed to promote environmentally sustainable practices on both the site itself and for businesses along the Great West Road.
Andy Portlock, CEO of Hadley, said: “Delivering the homes, infrastructure and social value London needs requires genuine collaboration between the public and private sectors — across local, regional and national levels. This project embodies that spirit. By working closely with the London Borough of Hounslow, the GLA, and through ongoing engagement with residents and businesses, we’ve brought forward a bold, sustainable neighbourhood vision grounded in partnership and ambition.”
The project’s design team includes Haworth Tompkins, Studio Egret West, Metropolitan Workshop and DRMM. Turley is the planning consultant.
