Furious parents claim children will be left kicking their heels if controversial plans to build on playing fields in Heston get the go-ahead.
More than 100 new homes have been proposed for green sites across Brabazon estate in a desperate attempt to solve Hounslow's social housing crisis.
Hounslow Homes, which announced the plans earlier this month, insists they will help curb the growing menace of antisocial behaviour on the estate but residents believe the new buildings will turn their pleasant estate into a concrete jungle.
Sandra Middleton, of Wright Road, said: "I've lived on this estate for 30 years and it's going downhill. There are needles around the garages and in the roads and those fields are the only places children can play safely."
Although the estate's main green will be preserved under the plans, residents are concerned that several smaller fields will be lost and have already collected more than 300 signatures on a petition demanding a big rethink.
A spokeswoman for Hounslow Homes said staff were looking into residents' concerns following consultations and may resite homes closer to the front of the estate.
