SESSION 18
MATERIAL PRACTICES THAT LIBERATE SELF-BUILDERS
This session calls for presentations on practices and experiments with non-industrialized, localized, and collaborative construction materials. Green schemes have become a norm for development projects, and private and public construction sectors in so-called global South have been seeking to balance ecological resilience with a pressure to modernize. The ecological and economic ambitions are sometimes at odds, and the conflict is most detectable in construction material use and regulations. For instance, in Rwanda where the session conveners practice, rural brick kilns and thatch roof have been banned in 2003 and 2007, respectively, to protect the forests and grass lands, and to ensure worker safety. But the modernization and industrialization of roof sheets and brick manufacturing may have been parallel motivations, and not primarily driven by environmental considerations. Adobe blocks were also banned in 2006, although the state is due to reinstate them after a consortium of public and private construction institutions issued an improved structural and safety codes. The reversal of a debilitating law was welcomed. It demonstrated the agencies of design and building disciplines to bring back a key accessible building material for the rural poor, and to stand with the underrepresented self-builders everywhere. The session welcomes case studies, policy examples, and organizational structures built around construction materials made by local human power and resources that satisfy the global development industry’s ambition to modernize, while supporting self-builders to build more durably and resiliently.
Presentations
Back to Earth: Advanced mud construction in the Himalayas
This paper proposes stabilized and reinforced rammed earth construction as both the continuation of traditional cultural practices in the Himalayas and an innovative technique that meets modern codes, marrying indigenous knowledge with building science to liberate local construction practices.
Material security and ecological insecurity: the quest of sand for building and coastal destruction in West
Urbanization is recognized as one of the most significant transformations of the world. Yet, the question of the supply of materials needed to build cities and their infrastructures is often taken for granted. This communication will show how crucial this factor is in West Africa, where the quest for sand is a source of conflicts and coastal destruction.
Local Materials, Global Ambitions: Self-Building Practices in Rwandan Housing Projects
Construction sectors in Rwanda have been seeking to balance ecological resilience with a pressure to modernize. This paper investigates non-industrialized, localized, and collaborative construction materials and methods by self-builders that may satisfy the modernization ambitions in East Africa and beyond.
Lost in compliance: speculative futures of self-build
Brick after brick, zinc after wood, South Africans have built their own homes. Currently, the strong tradition of self-build’s is being eroded, being replaced by stronger state control through regulations. The presentation will reflect, examine and speculate on concrete spatial conditions for restoring self-build as a participatory tool for housing.
