How to speed up your home renovation, and save on energy bills in Australia

According to The Australian Financial Review, it's been used for schools and offices already, but the prefabricated and sustainable cross laminated timber technology is now being used for the first time in Sydney to build an energy efficient Passive House.
Large-scale examples such as Lendlease's award-winning cross laminated timber (CLT) office towers in Sydney and Brisbane have already shown the speed benefits of prefabricated timber in commercial construction, but architect Knut Menden has applied it for the first time to build a one-bedroom extension to an existing pre-war home in Balgowlah.
It took just 15 hours to assemble the slab, walls and roof − and meant craning panels as tall as 11 metres over the existing home into the backyard. But CLT technology also works well for energy-efficient homes built to the German Passivhaus Standard, which demands a near-airtight building and which cuts a home's energy needs by as much as 90 per cent, Menden says.
