It concerns the Mapungubwe Interpretation Centre in South Africa, designed by Peter Rich Architects from Johannesburg. The project won the World Building Award at the World Architecture Festival (WAF) held in Barcelona last month.
The Mapungubwe Interpretation Centre, which is built to house artifacts from the region's prehistory, was constructed using local materials and using the skills and labour of local people. Unemployed South Africans were trained in the manufacture of earth tiles and in building the timbrel vaults.
Timbrel vaulting (or "Catalan vaulting") is being rediscovered as an ecological building technique because it saves large amounts of building materials and thus embodied energy. This also makes it a cheap building method, at least in regions were hand labour is affordable. Via Sergio Carratalá.
