Your Home

Your Home is a Commonwealth Government funded information source or ‘guide’ to building, buying or renovating a home.

In 2017 ACIL Allen was commissioned to undertake a strategic review of Your Home. This review found that Your Home provides information that can be used by building professionals, including as a means of encouraging behavioural change by consumers who they interact with. This review also found that Your Home is unique and stands apart from other information on home design and renovation. It is a highly-regarded resource and there is unanimous support for government continuing to maintain it.

Based on these findings Your Home is being refreshed, starting with a minor update in 2019 in preparation for major changes in the future. To view the Your Home resource visit
