The study explores the possibility that a transition zone can become a ‘filter’ that surrounds an urban core.
As a filter, the transition zone can regulate and rehabilitate ecosystem services to support human well-being.
The main research question focusses on how eco-systemic development can act as a filter while supporting human well-being.
The two sub-questions concern (a) how architecture can become a buffer between urban and suburban areas in Pretoria,
and (b) how architecture can aid in ecosystem rehabilitation to regenerate urban and human well-being.
Through the research done in this study, it is evident that transitional zones around city centres are commonly derelict and unsafe.
Human well-being is under pressure as a result of the increasing degradation of ecosystem services, which is brought about by human misuse and urban densification. As cities and human populations grow, urban cores expand. This expansion results in constant re-zoning as well as the demolition and degradation of existing spaces (Preston, 1966:240). Basic human well-being is dependent on successful ecosystem services and the biodiversity of urban environments (Bolund & Hunhammar, 1999:299).
This study aims to identify, reintroduce and rehabilitate ecosystem services on an urban edge to facilitate the health and well-being
of the community living there. The study addresses three main themes, namely:
(1) urban zoning and development, (2) human well-being, and (3) ecosystem-service rehabilitation and reintroduction.
By analysing the themes of urban development, well-being as well as social sustainability and ecosystem services, different theories and principles are identified to provide lenses through which the dissertation will be approached. The main lens is that of Vitruvius and the principles
he sets out in Ten books on architecture, which relates all design decisions back to nature.
Other theories, such as Ernest Burgess’ concentric circle model and the circular economy theory, and the guidelines
of the Living Building Institute led to the selection of the site, the development of the urban framework and the design of the intervention.
By combining these theories with a programmatic intervention, which was derived from the site and themes, the end result aims
to revive the community, the well-being of its members and to reinforce the existing development while ensuring
ongoing rehabilitation of the ecosystem services.
This intervention aspires to become a catalyst according to which all transition zones in urban environments can be
transformed from eye sores and barriers to filters and activators. / Mini Dissertation (MArch (Prof))--University of Pretoria, 2020. / Architecture / MArch (Prof) / Unrestricted
