Nulook Homes and Solar Dwellings won HIA Australian GreenSmart Display/Project Home and HIA Australian GreenSmart Energy Efficiency for a fully electric home. The categories are partnered by The Australian Reinforcing Company and Stegbar respectively.
Their winning Catalina 10-star NatHERS-rated sustainable home showcases the possibilities of ultra-efficient, all-electric housing. The home achieves 105% net zero performance through passive solar design principles, a 10kW PV array with battery storage, EV charging infrastructure and dual-plumbed greywater reuse.
Thermal performance is optimised via slab-on-ground construction, high thermal mass (locally sourced recycled bricks and rammed limestone), airtight building fabric and low U-value UPVC windows. Smart zoning and natural cross ventilation reduce the need for mechanical heating or cooling, while intelligent automation systems manage lighting, shading and energy consumption in real time.
Tallwood Custom Built Homes won HIA Australian GreenSmart Sustainable Home, partnered by ActronAir, for their Eco Barnhouse. Nestled within the Witchcliffe Ecovillage, the winning home stands as a beacon of sustainability within one of the world's most eco-conscious residential developments.
The innovative dwelling is a remarkable 140% carbon offset and achieves complete self-sufficiency in renewable energy and water resources. At its core, the home features a 10kw photovoltaic system connected to a central storage battery and the village microgrid, allowing excess energy to power electric vehicles or contribute back to the Western Power grid.
Progressive Building from NSW won the 2025 HIA Australian GreenSmart Home of the Year for a standout Sydney renovation which proves that uplifting existing housing stock can deliver big on sustainability, comfort and design.
With a focus on passive house principles, the renovation features all-timber construction, high-efficiency insulation, heat recovery ventilation, and solar system with battery integration. Smart energy monitoring systems respond dynamically to solar supply, enabling the home to run nearly off-grid.
Clipsal by Schneider Electric, partner of the HIA Australian GreenSmart Home category, are creators of home electrical products and solutions to enable technology for an ever-changing world.
HIA Australian GreenSmart Awards recognise the best in sustainable housing with Award winners and finalists making a positive difference to the environment by building energy efficient and comfortable homes.
HIA Managing Director Jocelyn Martin said the HIA Australian GreenSmart Awards set the benchmark for the latest in environmental design excellence and sustainable building practices.
“Consumer demand for practical, affordable and durable environmental solutions for residential housing is more evident now than ever before. Our GreenSmart Awards highlight HIA members who excel at delivering year-round comfortable homes into the market.
“We are dedicated to recognising excellence in environmentally focussed design, innovation and construction.
“Each winner and finalist is congratulated for achieving success at a national level,” concluded Ms Martin.

New rules add thousands to the cost of a new home as Tasmania falls years behind on housing
From today, every new home built in Tasmania must meet the full Livable Housing Design requirements. The Housing Industry Association says this adds thousands of dollars to the cost of building a home, at a time when Tasmanians can least afford it.
Rules for managing the risk of falls have changed - are you up to date?
Changes to Western Australia's requirements for managing the risks of falls will commence on 1 October 2026, introducing new expectations for builders, contractors and workers undertaking tasks where there is a risk of falling.
Livable Housing Design: final stage now in force
As of today, 1 October 2026, all new building work in Tasmania, unless exempt, must comply with all requirements of Part H8 Livable Housing Design of NCC Volume Two.
ACT housing approvals slump puts 2030 target under pressure
“The ACT’s housing supply pipeline is weakening, with building approvals in the three months to August halving compared with a year earlier,” said HIA Executive Director ACT and Southern NSW, Geordan Murray.
