Liveability and accessibility in higher density urban housing and precincts are critical to maximise investment and minimise future risks to our community. This research was guided by a need to shift from a cost-based focus to better understanding the benefits and long-term value derived from liveable and accessible housing precincts. It aims to build a better understanding also 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. The findings are informed by a review of industry and academic literature (April to October 2020), and case studies in both Brisbane and Perth supported by 23 interviews with industry stakeholders (October 2020 to May 2021). The research has developed a Liveability Framework for Medium to High-density Social and Affordable Housing (the Liveability Framework). 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.
