Government plans to ease planning rules in England for three years have been amended to give neighbours the right to be consulted on building work.
It comes after 26 coalition MPs - 16 Conservatives and 10 Lib Dems - voted against the government and now Communities Secretary Eric Pickles has written to MPs setting out a "light-touch neighbours' consultation scheme".
He said he wished to tackle "head on" concerns about the effects the plans would have on "neighbours' amenity".
Ministers announced last year that they wanted a three-year relaxation of the planning rules to allow single-storey extensions of up to eight metres for detached houses and six metres for other houses to be built without planning consent being required.
They argue that this will bring economic benefits and boost the building trade. But the proposal, which is still under consultation, has angered some local authorities and is also opposed by Labour.
MPs are concerned the plans may result in permanent unsightly developments, over which local communities will have no say.
Under the revised scheme, as set out by Mr Pickles, homeowners wishing to build extensions under the new powers would notify their council with the details and the local authority would then inform the adjoining neighbours.
If the neighbours do not object the development can proceed, but if they do raise concerns the council will have to consider whether it had an "unacceptable impact on neighbours' amenity".
Mr Pickles said this would allow ward councillors to be involved. The application could also be considered by a planning committee - as is the case in the current planning process - if the council deemed it appropriate, he added.
