This design exclusively uses natural building materials, bamboo, wood and stone, to create ample and comfortable environments, in a minimalist and elegant style. The large windows allow total natural lighting in the living and dining room and kitchen, simultaneously allowing connection with the living space in the outdoor deck. The stone walls, double-sided bamboo walls and the chimney offer a thermal environment for a range of climates. Its inverted roof allows higher amplitude in the bedrooms and social areas. 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.
