The fate of the “hideous” Bedfont Pitts will be in the hands of the secretary of state following the conclusion of a public inquiry this week.

The hearing at the Hounslow Civic Centre into the proposed development project was finally completed after an unexpected six-week delay.

The long-awaited inquiry started on June 24 and was only expected to last around four days - but it was adjourned because the consultation period in relation to the environmental statement was still open.

Inspector Martin Pike said on Friday there was no indication from the Government that the environmental statement was not in accord with the regulations.

Developers Trehaven Group want to transform the “eyesore” - which has been plagued by illegal motor cross riding and car burning - into a community park with recreational facilities.

But an inquiry was ordered because it is a green belt site. The planning application is not opposed by Hounslow Council.

James Maurici, representing the council, said: “The call-in proposals provide a rare, and quite possibly a unique opportunity to make significant improvements to what is heavily degraded green belt land at Bedfont Road.”

The proposals have had a huge amount of local support from residents associations, councillors and Fairholme school and it’s pupils.

The council failed to enforce against unauthorised concrete manufacturing on the trading estate in the 1960s, and in 1975 an established use certificate was issued.

Mr Maurici said: “The failure to successfully enforce against the concrete manufacturing use as well as lack of resources has led to the trading estate being what it is today.

“The area of the green belt in which the call-in site lies is extensively damaged and its condition will continue to worsen - to degenerate - if the call-in proposals are refused permission.”

The Greater London Authority described the trading estate as a “complete mess,” the inquiry heard.

Keith Lindblom QC, representing applicants Trehaven Group, said the proposed development would not harm the green belt, adding: “There will be no damage to its appearance, which in fact will be enhanced.”

He added: “These benefits will be appreciated daily by thousands of people.”

Chartered town planner Mr Pike said he would be ready to submit his report in early September.
