Every day the city plays out its spectacle unnoticed. This quotidian context is one which is full of complexity, spontaneity and possibility. It is here that architecture can engage with both the city and its user, space and experience; challenging conventional architectural typologies. It is within public space, that architecture can both enhance and celebrate the everyday. This project investigates all of these aspects within the city of Pretoria and more specifically along Van der Walt Street, focusing on the urban cavity at Munitoria. Surveillance is conceptually used to experience this spectacle, on multiple levels of enterpretation, where the architecture is reduced to support both the concept of surveillance and its experience.
