Light House Architecture & Science and 360 Building Solutions won HIA Australian GreenSmart Sustainable Home for a compact, 7.9-star energy-efficient home which cleverly adapts to an awkwardly oriented and sloping site to optimise solar passive gains.
Sustainable features include salvaged Blackbutt timber, uPVC window frames and insulating glass units, a high-performance hot water system, 10,000-litre water tank, airtight LED downlights and a sub-surface irrigation system for the native vegetation garden beds. This category is partnered by WoodSolutions.
The duo also won HIA Australian GreenSmart Renovation/Addition Project for a thoughtful renovation that refreshed a tired and uncomfortable 1960s Canberra duplex into a modern, energy- and water-efficient home. The decision to work within the existing footprint of the building to generate sustainable lifestyle outcomes allows the owners to experience more comfortable and functional living quarters while remaining in their neighbourhood of choice.
The judges were impressed by the design and construction team’s ability to bring a whole new lease on life to the existing structure by creating a light-filled, functional and sustainable dwelling for the owners to enjoy for years to come. This category is partnered by Holcim.
The 2023 HIA Australian GreenSmart Home – the highest accolade presented at the 2023 HIA Australian GreenSmart Awards – was won by Blue Eco Homes from New South Wales for an exceptional energy efficient dwelling that is fully accessible, multi-generational in design and built to a BAL-40 rating.
In congratulating the winners, HIA Managing Director Graham Wolfe said HIA Australian GreenSmart Awards recognise HIA members who deliver the latest in environmental design excellence and sustainable building practices.
“With the incoming changes to the National Construction Code, energy efficiency, water saving and condensation are important considerations for clients, designers, builders and material suppliers alike.
“HIA’s commitment to sustainable building outcomes through environmentally focussed design, innovation and construction has not altered over the 23 years the HIA GreenSmart program has been running. Our members demonstrate that comfort, security, innovation and value for money can co-exist in a sustainable built environment.
“Each winner and finalist is congratulated for achieving success at a national level. They are at the top of their field and are committed to building sustainable homes for their clients,” concluded Mr Wolfe.
The HIA GreenSmart program began more than 23 years ago and is a voluntary initiative available to HIA members.
The Awards major sponsor, the Nationwide House Energy Rating Scheme (NatHERS) provides energy ratings for new dwellings and major renovations which helps create energy efficient, resilient and comfortable homes for the future.

In mid-June 2025, the NSW Premier released the Housing and Productivity Contribution (HPC) Works-in-Kind Guideline for public consultation.
Today the State Government announced proposed changes to the regulatory powers to investigate registered builders who may be unable to meet the financial requirements of registration. The announcement also included a long-awaited review of the Home Building Contracts Act 1991 (HBCA) and associated laws.
“Two cuts to the cash rate have seen the volume of detached house building approvals rise to be 3.2 per cent higher than the same month last year,” stated HIA Senior Economist Tom Devitt.
“Building approvals data released today highlights the magnitude of the task ahead if we are to achieve the Government’s target of building 30,000 homes in the ACT over the next five years,” said Geordan Murray, acting HIA Executive Director ACT and Southern NSW.
