Around 2,000 homes would be created on open land around Bedfont Lakes Country Park, in Bedfont, under proposals developed by Hounslow Council in conjunction with bosses at Heathrow.
Bedfont Lakes Neighbourhoods, as the council has dubbed the development, would consist of four distinct quarters with a mix of apartments and houses separated by so-called 'green fingers' of land providing a habitat for wildlife.
A 'Heathrow Gateway' business hub, featuring offices and hotels, would also be built around a new Bedfont train station at the Clockhouse Roundabout. This would create between 12,000 and 20,000 new jobs, according to the proposals.
The new train station would be part of the long-touted 'Southern Access' rail route, linking the existing Feltham-Ashford line with Heathrow Terminal 5.
An 'Airport Business Park' situated around the existing Hatton Cross tube station, meanwhile, would act as a centre for airport-related commerce including logistics companies.
"Places that people want to live in and where businesses want to invest"
The idea of a Heathrow Garden City was first announced at an aviation conference last summer by the airport's chief executive John Holland-Kaye.
He said at the time a third runway could be the catalyst for regeneration around the airport, including a garden city with 9,000 new homes in Hounslow.
Detailed proposals have just been published by the council as part of its West of Borough Plan - a blueprint for the future use of land encompassing Feltham, Hanworth and Heston, among other areas.
They only mention 2,000 new homes but also include a significant amount of new hotels, offices and industrial buildings on the airport's doorstep.
In a joint introduction, Mr Holland-Kaye and council leader Steve Curran write: "Together we can make places that people want to live in and where businesses want to invest."
Review of green belt land in Hounslow
They also state that change is needed whatever the outcome of Heathrow's bid for a third runway - a government decision on which is not due until this summer.
"This joint visioning and many of the proposals - such as the new rail access and station - are essential regardless of the Government's decision on the location of additional runway capacity," Mr Holland-Kaye and Councillor Curran write in the joint foreword.
A recent poll suggested MPs were twice as likely to back a third runway at Heathrow as they were to support a second one at Gatwick.
The latest consultation on the council's West of Borough Plan includes a review of land designated as metropolitan green belt, which is likely to prove controversial.
The consultation document states the review is needed to see whether any green belt land could be used to meet the demand for new homes, 12,330 of which are needed across the borough by 2030 according to the London Plan.
Public consultation on the West of Borough Plan, including the Heathrow Garden City proposals, will run until Monday, February 22, at 5pm. You can have your say by clicking here .
