The old post office building in Walter Sisulu Drive opposite the Cape Town International Convention Centre was acquired by the ABC Group for development purposes. The existing 5-storey building is located on this narrow-shaped rectangular property in an excellent position within the City’s Central Business District. Through an iterative design process and urban design analysis, the concept was developed to enable a tall building to be developed on this property. Urban Dynamics lead the team of professionals and successfully undertook the statutory land use application process for the proposed 145m tall hotel building (tallest in Cape Town @ 2021). This landmark development will contribute most positively to tourism and to the international stature of the Cape Town’s CBD.
