Hadley Property Group have submitted a hybrid planning application for the transformation of 980 Great West Road in Brentford, west London.

Spanning 13 acres, this pioneering development aims to deliver over 2,300 homes (with a mix of tenures including Build to Rent, Co-living, Purpose-Built Student Accommodation and 35% Affordable Housing) and 330,000 sq ft of commercial space to support a diverse and sustainable local economy.

The scheme reimagines the prominent GlaxoSmithKline House site along the M4 corridor not only as a vibrant new community, but as a model for regenerative, circular development and long term social value.

The co-authored masterplan has been led by Haworth Tompkins, with Studio Egret West, Metropolitan Workshop LLP and dRMM as plot architects, Studio Egret West as landscape architects, Turley as planning consultant and Michael Grubb Studio as lighting designer.

Rooftop Conservatory

The project's pioneering low-carbon strategy retains the basement and substructure, significantly shaping the masterplan — heavily influencing the proposed building heights and locations, while also freeing up the ground floor for active uses. 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.

Studio Egret West are leading the design of the retained tower, which will contain generously proportioned homes with oversized balconies, large communal areas, shared amenity spaces and a large rooftop conservatory.

The retained tower

Reconnecting the historical island site to Boston Manor Park, the River Brent and Brentford High Street is also key to the site’s placemaking credentials. Alongside our work on the tower and the adjacent affordable housing, Studio Egret West has designed a generous and accessible landscape that sees more than 60% of the site given over to public realm, including play areas, gardens and riverside access.
