Only 837 car parking spaces will be built alongside almost 2,000 new homes as part of a new Greenford development on the former GSK site, sparking fears of congestion.
Developers Greystar have submitted an application to Ealing Council for 1,965 homes along with shops, a supermarket, restaurants, cafés, leisure facilities and offices .
Following consultation the area in Greenford Road, formerly the GSK and J. Lyons site, will now feature a new two-form entry primary school and a healthcare facility.
But the application proposes to build only 837 car parking spaces, leaving more than half of residents without a spot.
Greenford resident Robert Rowe, who has lived in Oakfield Gardens, near Greenford Road, for 52 years, said he was pleased with the development but fearful of congestion.
'Greenford could be chock-a-block with cars'
Mr Rowe, a retired maintenance electrician who worked on the GSK site, added: "I should think there will be up to 2,000 extra cars in the area with 2,000 residents.
"It is possible that if there is one car per resident, and with a supermarket and the school, the area will be absolutely swamped with cars.
"Where do they all go and where do they all stay overnight?
"Greenford could then be chock-a-block with cars. With a school there could be total congestion and traffic won't be moving at all in the area.
"It is a good thing that a brownfield site is being developed but I am very concerned about the congestion."
Initially Greystar wanted to build 2,060 homes on the 20.3 acre area, but that has been reduced to 1,965 with the tallest building dropped from 24 to 19 storeys.
The 19-storey tower is one of eight blocks to be built, comprising 4, 6, 7, 8, 14 and 15 storey blocks.
It is hoped that construction will start in early 2017.
A Greystar spokesperson said: "We understand that transport and traffic is a sensitive matter and we have listened to local residents throughout the consultation process.
"We have taken advice from Ealing Council and Transport for London in designing the planning application and in the allocation of car parking spaces.
"The site is ideally located, within easy walking distance of public transport, and we will invest in measures to promote walking and cycling. We have taken a number of steps to reduce car ownership, such as the provision of a car club.
"As a result of this package of measures, we have been able to provide a level of car parking that will meet the needs of future residents. We will continue to work with the Council and TfL to ensure the development does not have a negative impact on local roads."
