Making apartments affordable: moving from speculative to deliberative development

Urban planning policies in Australia presuppose apartments as the new dominant housing type, but much of what the market has delivered is criticised as over-development, and as being generic, poorly-designed, environmentally unsustainable and unaffordable. Policy responses to this problem typically focus on planning regulation and construction costs as the primary issues needing to be addressed in order to increase the supply of quality, affordable apartment housing.

In contrast, this paper uses Ball's (1983) 'structures of provision' approach to outline the key processes informing apartment development and identifies a substantial gap in critical understanding of how apartments are developed in Australia. This reveals economic problems not typically considered by policymakers.

Making apartments affordable: moving from speculative to deliberative development

Using mainstream economic analysis to review the market itself, we find high search costs, demand risk, problems with exchange, and lack of competition present key barriers to achieving greater affordability of apartments and limit the extent to which 'speculative' developers can respond to the preferences of would-be owner-occupiers. The existing development model, which is reliant on capturing uplift in site value, suits investors seeking rental yields in the first instance, and subsequently capital gains, and actively encourages housing price inflation. This is exacerbated by lack of density restrictions, such as has been the case in inner Melbourne for many years, which permits greater yields on redevelopment sites. The price of land in the vicinity of such redevelopment sites is pushed up as landholders' expectation of future yield is raised. All too frequently, existing redevelopment sites go back onto the market as vendors seek to capture the uplift in site value and exit the project in a risk-free manner.

This paper proposes three major reforms, which together would enable development of better, more affordable apartments for housing consumers:

  • Firstly, that the market for apartment development be re-designed, following insights from the economic field of 'Market Design' (a branch of Game Theory). A two-sided matching market for new apartments is proposed, where demand-side risks can be mitigated via consumer aggregation.
  • Secondly, consumers should be empowered through support for 'deliberative' and 'do-it-yourself' (DIY) development models, in order to increase competition, expand access, and promote responsiveness to consumer needs and preferences. A 'Smart Housing Market' is proposed to broker the necessary connections and simplify the process.
  • Finally, planning schemes need to impose density restrictions (in the form of height limits, floor space ratios or bedroom quotas, for example) in localities where housing demand is high, in order to dampen speculation and de-risk development by creating certainty. Restrictions on over-development on larger infill sites can be offset by permitting intensification of 'greyfield' suburbs. Aggregating existing housing lots to enable precinct regeneration with moderate height and density increases would permit better use of airspace thus allowing design outcomes that can optimise land use while retaining neighbourhood amenity.
