CPD 710 ENERGY, WATER & WASTE IN THE BUILT ENVIRONMENT: Brickworks waste in the built environment, its possible re-use & recycling methods in the South African context. “Architecture starts when you carefully put two bricks together. There it begins.” – Ludwig Mies van der Rohe BACKGROUND: The Regionalist structural design found in the Pretoria region is characterized by the use of clay brickwork for load bearing walls. Fisher Le Roux & Mare (1998: 124-140) discusses the reasons why clay bricks are so predominant in the residential architecture of Pretoria, which he refers to as the Third Vernacular of South Africa.

Moreover the character of the Pretoria populous and the regional architecture that established had a “strong... affinity for the natural, whether in landscape or the more subtle rootedness to the soil...” (Fisher et al 1998: 138) and the use of clay in bricks encompassed this connection with the milieu. As well as the aesthetic and colour of clay bricks allowed a connection with the natural environment. The climatic situation of the region also had guidance in choice of appropriate material and clay bricks were used as thermal mass.
