@Jerry, Any hint of increasing housing standards would send the large house builders squelling to their lobbyists and putting the brakes on so little chance of any political inducement for change unless the price of gas quadrupled. Plenty of members here work on new housing stock and can probably attest to the dire standards of design and workmanship still employed so don't hold your breath.
Didnt this happen a few years back? Gas was meant to of been stopped on new build a few years back but the builders kicked off as it was too expensive for them to do it and as the government said they would build 1 million homes by something like 2020 they held them to ransom so the government backed down.
