Abstract
Cohousing for Ageing Well (CHAW) is a funded collaborative design research project undertaken by Damian Madigan for Office for Ageing Well (SA Health Department), the South Australian State Planning Commission, the SA Department for Infrastructure and four inner-Adelaide Councils: the City of Unley, City of Burnside, Town of Walkerville and the City of Prospect. The project expands Madigan's Bluefield Housing model first developed in his Alternative Infill thesis and subsequently tested in his Established Manors Missing Middle competition, whereby existing homes are retained, altered and extended to provide new small-scale housing located around high quality shared gardens. Where these precedent projects explored the Bluefield model across two adjacent and amalgamated sites, the CHAW project explores the infill possibilities across single allotments. Ignoring minimum allotment size in favour of appropriate design fit and scale - a guiding principle of the Bluefield model - the project demonstrates sensitive infill housing opportunities across four sites ranging from 325 sq m to 920 sq m.
Recognising the shortage of high-amenity single bedroom dwellings available in the suburbs, the project explores a number of single bedroom designs that provide increased liveability over existing Accessory Dwelling Unit, so-called 'granny flat', or 'tiny house' models. And where cohousing traditionally extends across large land holdings accommodating twenty or more dwellings, the project explores a cohousing 'lite' approach, where degrees of sharing are offered, ranging from a full common house in the Extra Large Scheme, to a shared laundry in the Small scheme. Each of the four schemes shares the gardens, with a variety of options demonstrated for the locations of clothes drying, rubbish bin, shedding and car parking. Focussed on housing to suit ageing in place and multi-generational living, the project was developed to inform low-scale and low-intensity infill housing options that are suitable for residents of any age. The next step for the project is to develop planning policy that will see the model adopted as a new infill housing form in South Australia's new state-wide Planning and Design Code.A comprehensive Design Report presents the four detailed design schemes, along with the underlying design principles that can be deployed by others seeking to mimic the housing model.
