Hadley, the company proposing the redevelopment of the former GSK House on Great West Road is to hold another round of consultations.

It says that these sessions will reveal details of the ‘advanced masterplan’ for the scheme with designs for public spaces and amenities and ‘new visuals that bring the proposals to life’.

Some computer-generated images have been published ahead of the meetings which appear to show a new public plaza with people dining al fresco underneath the Chiswick Flyover (see above) and another shows people seated in a garden area in a public square amid tall buildings.

The consultation events are taking place on Wednesday 11 June from 5–8 pm at The Potting Shed in Boston Manor Park (TW8 9JU) and on Saturday 14 June from 12–3 pm at Brentford Free Church, Boston Manor Road, (TW8 8DW).

Members of the project team will be present to answer questions. If you can’t make it in person, you can still view the consultation materials and share your thoughts online at hellobrentford.co.uk from 11 June.

It is understood that these will be the last consultation events before a full planning application is submitted later this year.

The redevelopment of the 13.4-acre site at 980 Great West Road is likely to be the largest construction project ever undertaken in Brentford with over 2,000 new housing units. Details of what Hadley is planning are emerging slowly, and the likely scale of the project only came into the public domain after the company submitted a scoping opinion as part of the planning process rather than at previous consultation events.

This revealed that the tower blocks within the scheme would reach up to 25-storeys high and contain a mix of flats, student accommodation and co-living apartments. The tallest building would include around 750 flats, 530 units of student accommodation and 330 co-living units as well as 900 square metres of commercial floorspace and up to 2,700 square metres of what is described as community floor space. In addition, there would be a section including a 15-storey building with around 750 more flats as well as a much larger proportion of commercial space.
