This design contemplates the need of a family that prefers vertical spaces. The living room has a double height that integrates both the first and second storeys, giving a greater sense of amplitude and scale. This design contemplates the combination of different natural building materials, like brick and bamboo. 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.
