Each unit is built with sustainability in mind, such as the solar panels on the roof, which only need four hours of daylight to generate enough energy to power lamps and mobile phones for a family. Due to its simple features (each house has 71 pipes and 35 panels) the homes can also be manufactured at scale and deployed efficiently, thereby minimising CO2 emissions throughout the entire process. In short, Better Shelter provides homes with big hearts and small environmental footprints.
