Terraform builds solar-powered machines that make the things people need. Housing is the result of the materials those machines make. We design a house once, make it in a factory, ship it and assemble it on site, and we are doing it with two systems at once.Sections is a kit of floor, wall, ceiling, roof and window sections with the services already inside. 16 sections fill a 40ft container and bolt into a house on site.Shell is an inflatable membrane filled in position with structural materials. The membrane is the formwork and the finished surface, the services are cast into voids inside the walls, and the cured building is lifted whole, moved and set down again within 24 hours.
