Conservative councils must put building new homes before "the privileges of a comfortable elite" or damage the party's chances at the general election, Planning Minister Nick Boles has warned.
In a shot across the bows of Tory-run town halls, he said they had a "responsibility" to free up sufficient land, and protecting the Green Belt and fine landscapes "must not become excuses".
Mr Boles has faced the ire of rural campaigners over his calls for a massive boost to construction, previously suggesting that a third more of the country should be built on to solve the housing crisis.
In an article for the Conservative Home website, he wrote: "It is right that decisions about where new houses should go should be made locally - by people who know their area best.
"But with that power comes responsibility: the responsibility to provide enough land to meet people's housing needs in full.
"Of course councillors should protect the Green Belt, our finest landscapes and areas of special environmental value. Of course they should locate as many new homes as possible on brownfield sites.
"These are admirable objectives which the Government strongly supports. But they must not become excuses for local councils not to provide enough homes for the next generation."
He went on: " The Conservative Party wins elections when it backs people's ambitions to create a good life for themselves and their families. It loses them when it defends the privileges of a comfortable elite.
"As the next election approaches, David Cameron is clear that the Conservative Party should be saying Yes to Homes."
His latest appeal to local councils came as the Government hailed the role of its schemes in reviving the UK housing market.
He released figures showing 3,749 people had got on the property ladder through the NewBuy scheme that allows people to buy new-build homes with a deposit of as little as 5% of the value of the property.
More than 25,000 have so far benefited from that and other schemes, he said, which "clearly show the housing market is moving again".
But Labour said the NewBuy figure represented only 5% of the 100,000 Prime Minister David Cameron announced it would help.
Education Secretary Michael Gove stressed the importance of the planning reforms, claiming they could impact on the academic achievement of children who were currently unable to have their own bedroom.
He said the reforms were " social justice changes", adding: "Virginia Woolf wrote about a room of one's own and the fact that, throughout history, women often didn't have a chance to fulfil their creativity because they didn't have a room of their own in which to write.
"There are children who don't have, poorer children who don't have rooms of their own in which to do their homework, in which to read, in which to achieve their full potential.
"Nick Boles' planning reforms will make it easier for more homes of a larger size to be built for children. And that's why, when people oppose these planning reforms, I think they're actually standing in the way of helping our children to grow tall."
