Abstract
This paper examines the transformation of open space and how it compares to older residential development. A study has been conducted at the residential level because neighbourhoods have been a basic unit of city design throughout the recent history of urban settlements. Furthermore, the neighbourhood is a more humanly relevant scale of urban development. The method adopted for this research was a comparative urbanism by comparing old and new residential areas. This study found that incremental redevelopment of old residential areas through both re-subdivision and intensification of development on existing allotments has resulted in a progressive loss of open space. However, the study also confirmed that the current supplies of open space across all the study areas (old and new residential areas) are relatively similar. The main difference between the open space supply in older and newer residential areas comes down to the ownership of land (i.e. the proportion of public versus private open space). The study demonstrated that older residential areas with large allotments have experienced a significant loss of private open space – originally from 50%, to current levels of 23–30%. The paper concludes that there is a need for a holistic approach to the provision of public and private open spaces to improve the quality of life at a residential level.
