ABSTRACT
A perennial applied development problem is that everybody needs shelter although, viewed globally, not everyone is able to secure what may be regarded as housing of an adequate standard. It is believed that 20 per cent of the world’s total population does not have access to decent shelter. Further, it is estimated that in the predominantly poor and middle-income countries that make up what is referred to as the ‘third world’ or ‘South’, perhaps as many as one-half live in homes that may be deemed substandard.
