Requirements: Design a simple dwelling to be constructed for under $300 to keep it’s occupants safe from the weather, allows them to sleep, and gives them a home and a sense of dignity. Factors to address: regionalism, sustainability, cost and replicability. Affordable housing: Self-built or self-improvable: that lowers the cost and works to reduce the potential for corruption. Low-tech: We want the dwellers themselves to build or improve or expand their house, as this will generate income for them and reduce the risk of value capture by landlords and rent-seekers. Local materials, preferably those that can be found or bought very cheaply. Build greener, cheaper and encourage sustainable homes and communities. Replicable.
