Australia experienced a self-help housing boom after World War Two which pl
ayed an important part in overcoming a serious housing shortage. This paper
looks at the magnitude of the boom and at the factors which made it possib
le. It argues that the basic factor motivating amateur builders was the abs
olute scarcity of accommodation rather than its high cost. There were signi
ficant regional variations in the extent of self-help activity. These are b
est explained by the extent of public housing provision. Where state govern
ments invested heavily in public housing there was less self-help activity.
The paper also traces the sources of finance used by owner-builders and th
e extent of co-operation amongst them.
