The recent exhibitions held by the developer Hadley on its plans for the development of GSK House at 980 Great West Roadhave revealed more information about what is being proposed.
The scheme, which will be the largest ever undertaken in Brentford, will contain around 2,000 flats across a range of housing types of which at least 35% would be classed as affordable, with 235 available for social rent. About a quarter of the units would be student accommodation and 852 would be for market sale.
These would be included in 12 blocks with heights ranging from 12-26 storeys.
There would be 23,345 sq m of commercial space 5,947 sq m of which would be on the ground floor. There would also be 7,000 sq m of play space, a GP surgery and pharmacy as well as multifaith/reflection spaces.
The developer is proposing to reuse most of the existing substructure and retain the basement space which would be used for car parking, cycle storage and plant.
The designs at the exhibition show a sculpture resembling a dinosaur at one entrance to the development and Hadly says it intends to make art a guiding them of the project with existing sculptures being relocated here and building materials being reused to commemorate the site’s history.

There will be a public plaza at the centre of the scheme called Boston Place with limited vehicle access which would contain gardens and play areas.
It is also proposed to make a virtue of the space beneath the motorway flyover which has been dubbed ‘Underside’ and will become a flexible public space with seating and planting where events would be held.

At the Boston Manor Park end, an arched gateway culminating in a woodland pavilion, would give access to the development.
The scheme will eventually increase public access to the waterside with facilities for water sports in the area.

The intention is to submit an application for the first phase of the development later this year with outline planning permission being sought for the rest of the project at the same time. This would then be considered by the borough planning committee sometime in early 2026 and, should permission be granted, construction work would commence in the third quarter of 2027.
If you have any questions about the proposals or would like to be added to the developer’s mailing list to be kept informed about what’s happening and future consultations, email communities@hadleypg.com.
