The construction of this large home took advantage of the natural building material found in abundance on site: stone. This was used to build the entire first storey, ensuring yearlong thermal comfort to all its indoor spaces. The second storey is built entirely with bamboo, stuccoed on the outside and varnished on the inside. This project is a clear example that natural building materials, if used in the right way result in an aesthetic, clean and sustainable design. Like every CASSA home, it integrates all elements of sustainability: rainwater capture, water cistern for storage, pump for redistribution inside the house, solar panels, LED lighting, efficient smokeless stove, gray water separation and reutilization in a family garden, and an underground black water treatment system.
