Consultation on plans to build 250 flats on an industrial estate has been extended following criticism by opposition councillors who say residents' views are not being heard.

The 4.8 acre Rainbow Industrial Estate, behind Raynes Park Station, is subject to a planning application from owners Workspace who want to redevelop the site to provide 3,400 square metres of business space and 250 new homes.

A consultation in June 2012 led to a complete review after the council's handling of the application was condemned by opposition councillors who said the council had allowed the developer to dictate its planning policy and had failed to listen to residents’ concerns.

A fresh statutory one week consultation period on the site's final planning brief was launched on June 20, but was extended following calls by Conservative and Liberal Democrat councillors at this week's cabinet meeting to give residents more time to respond with their concerns.

Speaking at the meeting, Councillor Gilli Lewis-Lavender, for West Barnes, said: "The report on proposals for the Rainbow Estate does not address any of the concerns raised previously by the residents of Raynes Park, Dundonald and West Barnes wards.

"Nor has there been any attempt to consult with the residents over these latest proposals.

"This is simply not fair or proper.

"A lot of people in my ward, and also in Raynes Park and Dundonald, spend many hours considering these reports and making very useful and sensible suggestions, but it seems to me that these submissions are totally ignored wasting much of their time."

A spokeswoman for the council said: "All the feedback has been an essential part of our extensive consultation and been fed into the Rainbow planning brief which we are giving residents four weeks to read and provide any further comments on."

The consultation on the final planning brief will end on July 20.
