Poll- otter architecture : For an urban environment sinking under layers of barriers : With focus on the boundary wall as an architectural medium to support the urban condition

The area of investigation for this study falls within a small urban island called Westbury. Situated 7km to the West of Johannesburg’s CBD, it is isolated from the adjacent urban fabric as a result of its historical and also recent development. Westbury itself also consists of a series of fragmented islands with undefined boundaries, weak urban blocks and a disorientated grid. The area has recently been identified as a high priority region for densification1 by the city of Johannesburg, supported by transport-oriented infra-structural investment. The questions raised by this study are contextualized against this backdrop. How could densification in Westbury be achieved towards the creation of a more inter-connected, cohesive, accessible and therefore sustainable urban environment? Following from this: How could Westbury be better integrated with the immediate surrounding urban fabric whilst combating its own fragmentation? What is the role of urban blocks and boundary conditions to help shape a future more integrated Westbury, and also towards meaningful place-making? In what ways can architecture contribute in order to improve the urban fabric that operates on various scales: from the very scale of the house to that of an urban boundary to that of the urban block and ultimately the greater urban network? The hypothesis outlined in this study is that architecture is too weak to stand in isolation, that a network of buildings is necessary to achieve a more sustainable, accessible, cohesive, and inter-connected urban environment. This is tested through a rigorous analysis of boundary conditions at different scales as reflected in the urban blocks of Westbury and the resultant architectural strategies. Finally, a block and its attendant boundaries is singled out to test the architectural contribution towards densification of the suburb, the making of place, and better inter-connectivity. The process is envisaged as driven from both the scale at which urban issues inform the architecture, and the reverse scale the architecture in Westbury informs the urban master plan. The architecture in style and scale sets the conditions for the proposed urban blocks. The boundary wall being the medium where urban meets architecture. “For these dreams to flourish in reality, we must recognise that there can be no ready-made solutions in housing, no recipes orMini Dissertation (MArch (Prof))--University of Pretoria, 2018.ArchitectureMArch (Prof)Unrestricte
