Design Specifications

This is a social housing typology for rural areas in Chile. The house model is 50 m² and it was designed for a family with 3-5 members. Considering the local climate, the bedrooms and living room are oriented to North. The service areas, kitchen and restroom are oriented to South. All windows and doors are in the North and South facades. The East and West facades of the house do not have windows, to save energy. The material selection criteria sought to employ nonvolatile organic compounds to protect children with cancer living in the house. The exterior high-performance exterior walls and roof work as protection for indoor climate control.
