Higher density multi-unit residential developments, such as townhouses and apartment buildings (henceforth ‘higher density housing’), have become an increasingly common feature of Australian cities. Across the country, 2016 marked the first time when construction began on more higher density housing than detached houses. New South Wales (NSW) already passed this milestone some years ago, and over a quarter of Sydneysiders now live in higher density housing.
In the light of this shift, Shelter NSW engaged the City Futures Research Centre to identify the major challenges confronting lower income and vulnerable residents in higher density housing. Shelter NSW is concerned to explore and highlight how contemporary urbanisation processes disproportionately affect more vulnerable social groups. These reports provide a summary of the research evidence currently available to answer these questions, as well as an indication of the gaps in evidence.
The trend towards higher density housing can bring both benefits and challenges, which are quite different to those associated with lower density, suburban development. These differences are apparent at various scales. In higher density buildings (‘the building scale’), factors like proximity between residents, and the need to share responsibility for building upkeep, create a different living experience to that of detached housing. In areas with growing quantities of higher density housing (‘the neighbourhood scale’), this densification can strain local services and reshape the area’s socio-economic mix. And in cities that have embraced the ‘compact city’ model (‘the metropolitan scale’), this policy objective puts pressure on governments to coordinate infrastructure planning and delivery, and to manage the social, economic and environmental effects of changing population patterns and urban form.
Many of these issues impact residents across the income spectrum, but different socio-economic groups have different resources available to respond to these pressures. Because lower income and vulnerable residents generally have less choice and less influence than other socio-economic groups, they are disproportionately affected by the challenges of higher density living. However, much of the research evidence currently available on the challenges of higher density housing does not explicitly consider the impact on lower income and vulnerable residents. Similarly, Australian governments have not adequately acknowledged and addressed the impact of higher density housing on lower income and vulnerable residents. For this reason, these reports focus on issues with higher density living that are specific to, or exacerbated for, lower income and vulnerable households. Where necessary, we have extrapolated from the more general research evidence to consider the impacts for lower income and vulnerable residents in particular.
In preparing these reports, we have kept our definition of ‘lower income’ and ‘vulnerable’ as open as possible. However, as a rule of thumb we consider the following definitions to be useful: • ‘lower income households’ refers to households in the bottom two income quartiles (earning less than $649 per week in NSW); and • ‘vulnerable households’ refers to households experiencing various forms of socio-economic disadvantage (such as low education, high unemployment, low-skilled occupations, poor English proficiency and single parent households), as well as people with physical or intellectual disabilities and victims of domestic violence. To decide which issues should be covered in the reports, a workshop was held with key stakeholders from across the housing sector. This workshop identified the major issues facing lower income and vulnerable residents at the building, neighbourhood and metropolitan scales. These reports are written with these key issues in mind, while drawing upon the existing research evidence. While much of the report material focuses on the NSW policy context, many of the issues raised are equally relevant across Australia and around the world.
To begin, Report One on the building scale considered the most important issues in both individual dwellings (e.g. apartments) and higher density buildings as a whole, and how these can influence the quality of life of lower income and vulnerable residents. Next, this report focuses on the neighbourhood scale to explore the different issues faced by lower income and vulnerable households living in areas with significant higher density development. The report identifies two key issues that particularly affect lower income and vulnerable residents at this scale: the socio-economic mix of the neighbourhood (‘diversity’), and the extent and nature of the services and infrastructure available in the neighbourhood (‘facilities’). Finally, Report Three will identify the metropolitan scale processes and policies associated with densification that have a disproportionate impact upon these groups.
