Motivated by discontent with the quality, design, and cost of speculative multi-unit housing provision in Australia, households and professionals alike are increasingly seeking alternatives. Recent years have seen an increase in the number and university of households seeking to collectively self-develop multi-unit housing in our inner cities. Housing projects have formed from ground-up movements, professional provocations, and state and local government interventions. This paper firstly summarises the previously identified benefits of ‘developing without developers.1’ Secondly, it investigates how the alternative structures of provision currently emerging across the country redistribute the tasks traditionally undertaken by developers among other network actors. This is done through the thematic analysis of in-depth interviews with key professionals from three multi-unit housing projects currently ‘developing without developers’. Asking the question “Without a developer, who does the ...?” the research identifies distinctly different perspectives are held by different professional groups. In conclusion, knowledge gaps and capacity deficits are identified among professionals assisting households to self-develop; outcomes which can be utilised to direct professional training programs and increase the capacity for multi-unit self-development.
