A retrofit of a Housing New Zealand home to improve living experiences of those on low incomes and a thermally detailed straw bale house in Central Otago were tonight judged the winners of the Sustainable Habitat Challenge.

After nearly two years designing, funding and creating their visions of more sustainable homes, teams in the Sustainable Habitat Challenge are set to hear the judges' verdicts.

This Tuesday 28 July Carters will begin a race against the clock to construct the final build phase of the perfect kiwi bach for charity auction on www.sella.co.nz.

With just eleven days until the Big Night In Telethon 09, the Big Build will be no mean feat
