Australia’s population is ageing rapidly, yet we continue to make housing choices as though we will never grow old. New housing typologies, including alternative finance and governance models, will be needed to provide housing options suitable to our ageing population. An emerging response is cohousing, which has the potential to provide liveability, affordability and connectivity benefits to residents. This paper reports on the outcomes of empirical research involving interviews with housing providers and professionals, as well as focus groups with older people. This research investigated areas of need, demand and desire amongst older people with regards to their housing needs and desires in old age, with particular reference to the potential of cohousing models in response to these gaps. Older Australians are a very large and diverse group. Age does not constrain the diversity of other demographic factors such as financial situation, health conditions and household structure (single or couple), which strongly influence the housing needs and desires of older Australians. Thus, there is not a single typology that will be suit older people—and this is especially so when it comes to cohousing—a relatively niche sector. Our research identified three different typologies of cohousing that may be appropriate as housing alternatives for different cohorts of older Australians. These are: deliberative development; low-income rental cohousing; and small-scale owner-occupied cohousing. This paper will describe these typologies, the market segments targeted by each and outline challenges and opportunities that each typology presents.
