The plan would allow homeowners to build extensions of up to eight metres without consent of the current law which is designed to protect neighbourhood amenity.
Last month members of the House of Lords voted through an amendment tabled by Lord True, the leader of Richmond Council, that would allow local authorities to exempt themselves from the relaxed planning rules.
It is expected the Government will be defeated next week with Labour, most LibDems and upwards of 20 Tory Rebels voting against the legislation who fear a big rise in disputes between neighbours about eyesore extensions.

Many fear that the new legislation will make it very difficult to protect large swathes of the Green-Belt.
