The Hope House is a low-cost modular housing solution under development for the relief organization Save-A-Generation, which works primarily to improve living conditions for the needy of rural Nicaragua. The home consists of pre-cut Agriboard panels, made from densely compacted waste straw. The prototype 280 sq ft unit can house a family of up to 6, and is planned to flexibly accommodate both living and entrepreneurial functions. The simple home is designed to be built in less than 3 days by crews with limited skills and resources, in locations which are often remote. The design includes an off-the-grid water purification system developed by Project Hope House, passive solar shading, and openings located to promote natural ventilation.
