Liveability and accessibility in higher density urban housing and precincts is critical to maximise investment and minimise future risks to our community. This research has developed a Liveability Framework for Medium to High-density Social and Affordable Housing. The intent is to guide decision-making around the design, development and management of more effective social and affordable higher density housing. Research was guided by a need to: shift the focus from a cost-based focus to better understanding the benefits and long term value derived from liveable and accessible housing precincts; building an understanding of government, industry and not-for-profit roles in shaping industry structure and driving new urban forms; and improving the adoption of liveable and accessible design outcomes. These findings are informed by a review of industry and academic literature (April to October 2020), case studies in both Brisbane and Perth (October 2020 to May 2021) and 23 interviews with industry stakeholders. The liveability framework, aimed at maximising future benefits and minimising risk, includes 53 sub-components and guidelines, across 5 components. The intent is for the framework to be used by our SBEnrc partners, and the social and affordable housing sector more broadly, to guide decision-making around the design, development and management of more effective, accessible and liveable social and affordable higher density housing.
