Ministers were forced into a U-turn over proposals to relax planning rules over home extensions following a threatened rebellion by MPs.
Solihull MP Lorely Burt (Lib Dem) was among those lobbying Ministers to think again.
A number of Conservative MPs were also opposed to planned changes to the Growth and Infrastructure Bill which would have allowed homeowners to build extensions in their back gardens without seeking planning consent.
They warned that the change would lead to disputes between neighbours.
Even after Local Government Secretary Eric Pickles promised to reconsider the proposals, MPs including Mark Pawsey (Con Rugby) and Chris White (Con Warwick & Leamington) defied party whips and voted against the Government in an effort to change the proposed law.
They backed amendments introduced by the House of Lords allowing councils to opt out of the new policy – helping to reduce the Government’s majority to just 27.
However, other critics of the proposals were happy to accept assurances from Mr Pickles, who urged MPs to give him time to draw up a compromise.
Ms Burt said: “It’s fair to say there were a lot of deeply unhappy Conservatives and Liberal Democrats.
“I lobbied Nick Boles, the planning minister, and it seems that the Government has listened.
“The original proposal would have led to numerous planning applications going through without any chance to object.
“It makes no sense to say we want to give more power back to local councils at the same time as taking power to determine planning applications away.”
Under the proposals drawn up by the Government, home-owners with detached houses will be able to build a single-storey extension of up to 26ft without the need for planning permission. Home-owners with any other house will be able to extend to 19ft .
Many MPs feared the measures will lead to increasingly frequent and bitter disputes between neighbour.
But Mr Pickles pledged the Government would think again – and would propose its own amendments to the legislation when it returns to the House of Lords.
He told the House of Commons he wanted to find a “sensible compromise”.
The Communities Secretary said: “I can announce that in the spirit of consensus, we will bring forward a revised approach on the contentious question of permitted development rights for home extensions when the Bill returns to the Lords.
“I believe that this is eminently bridgeable.”
