Uncontrolled suburban fringe developments create increased car dependency, social isolation and degradation of productive land. A continuation of this suburban growth model compromises the long-term sustainability of the city. The attractiveness of housing on the urban fringe is attributed to affordability and the space for families. Current higher density models do not adequately address the needs of families with children; therefore, significant priority must be placed on finding better design solutions to incorporate families with children into higher density infill housing.
The inadequate attention paid to affordability and family friendliness in higher density developments, together with the insensitive design of higher density infill models into existing streetscapes and neighbourhoods will further fuel suburban expansion.
The aim of this dissertation is to identify family-friendly planning strategies and guidelines that need to form part of future higher density multi-story developments in order to slow down suburban expansion. It further addresses the necessity why the current low-density suburban growth model needs to change. In order to be able to alter the current situation it becomes essential to investigate the reasoning of people’s decision-making over either the suburban model or the higher density apartment-style option. Since the majority of new buildings will occur through infill some densification strategies will also have to be discussed to provide sustainable higher density infill options.
