Hadley submits exciting plans for GSK site

Hadley has submitted a hybrid planning application for transforming the former GSK headquarters at 980 Great West Road, Brentford.

This project is a significant step in one of the UK’s most ambitious reuse-led regeneration efforts. The 13-acre site aims to become a new neighbourhood that aligns with Brentford’s character, featuring around 2,300 new homes across various tenures, including Build to Rent, co-living, and student housing, with 35 per cent designated as affordable housing. Additionally, over 320,000 sq. ft of flexible commercial, retail, and community space is proposed to support local businesses, education providers, social enterprises, and charities.

The project emphasises a reuse-first strategy, retaining the basement, substructure, and two existing campus buildings, including the landmark tower. This approach significantly reduces the site’s embodied carbon footprint while creating a distinctive masterplan. The retained tower, designed by Studio Egret West, will be transformed into spacious new homes, communal areas, shared amenities, and a rooftop conservatory.

Over 60 per cent of the site is planned as public realm, connecting the neighbourhood to Boston Manor Park, the River Brent, and Brentford High Street. New play areas, gardens, and riverside access will ensure an open and welcoming environment, with landscape design led by Studio Egret West.

The development is led by a top-tier design team, including Haworth Tompkins, Studio Egret West, Metropolitan Workshop, and dRMM as plot architects, with Turley as the planning consultant. The team has collaborated with the London Borough of Hounslow and engaged residents and stakeholders to shape a shared vision. The application is expected to be reviewed by the Planning Committee by the end of 2025.
