Taken together as a joint financial/ architectural proposal, this project has shown that with relatively simple adjustments significant benefits are possible relative to current market offerings – in terms of affordability, quality / performance and density / yield.

Leveraging CoDev’s technology, and through a series of stakeholder consultations, this project tests a range of townhouse typologies in different scenarios to help understand what inputs and processes are needed to achieve more affordable homes for first-home owners in West Footscray. The study shows that it is possible to significantly increase dwelling yield in desirable and high-amenity locations, working within current regulatory frameworks, where there is substantial supply of medium-large residential allotments and local council policy support. Small-scale, simple and effective ‘townhouse’-type dwellings with an emphasis on design quality can deliver liveable, practical and sustainable dwellings that work in sympathy with surrounding urban character.

The infill housing designs in this study place an equal emphasis on internal and external quality and performance of space, and aim to provide affordable, robust and adaptable dwellings that are feasible within current middle-suburban conditions in Australian cities. The financial modelling has placed an emphasis on reducing transactional and sunk costs and charges in favour of investing into quality of the building envelope which both improves affordability and increases value for owner-occupiers over time. The collaborative investigation highlights a significant need for future research into financing methods, bank valuation processes, and the relationship between dwelling provision and parking provision.
