This dissertation aims to challenge the existing built thresholds that are in place between South Africa and its neighbouring countries. In the words of Heidegger, “ A boundary is not that at which something stops, but as the Greeks recognised, the boundary is that from which something begins it’s prescencing.”¹ Boundaries and edges need to be created. They need to be made strong. They need to dominate and control. But borders must not be barriers. This study sets out to investigate the design of a border complex as a transition zone between two countries. It intends to encourage international connectivity, and encourage fair trade and travel, by addressing the functional requirements expectant of a border post, and ensuring the necessary control. Emphasis is also placed on movement through a site where many challenging physical constraints call for innovative design solutions, and where a harsh climate needs to be addressed. / Dissertation (MArch (Prof))--University of Pretoria, 2007. / Architecture / unrestricted
