Consultation has begun over plans to build more than 2,000 homes and a new supermarket in Greenford .
The development promises 1,514 rented homes, 546 homes for sale, communal space and 58,000 square feet of office space in Greenford Green on the former GSK and J. Lyons site.
Developers Greystar also propose 60,000 square feet of retail, including a new supermarket, and 49,000 square feet of space for restaurants and cafes.
A new pedestrian bridge over the Grand Canal Union has also been drafted and plans propose to re-open Berkeley Avenue to improve accessibility.
But residents have raised concerns that Greenford will struggle to cope with the increase in population that would come with the development.
Blogger Albertina McNeill, who writes for Positive Greenford and has lived in Greenford since 1991, said: "They (the flats) are going to bring in a large number of people in an area that already has problems.
"Problems with GP services, policing, school places and street drinking.
"I'm hoping if they do go ahead some money will go towards providing more services."
Glaxo House will also be refurbished to restore its status as a landmark building, developers said.
And there will be 1,073 new parking spaces and 2,519 cycle spaces provided throughout the site.
Developers added there will be the potential for a pop-up cinema, summer festivals and farmer’s markets.
The public were consulted this week and on Saturday (May 14), from 10am to 1pm, there will be a public drop-in session being held at the GSK site office in Greenford Road.
Greystar said they will listen and consider feedback from the public before submitting plans to Ealing Council.
