It may not be surprising to find something as extravagant as this house but the thing about this one is that it runs on solar power. Called the Stone Spray, this is a solar-powered 3D robotic printer that creates building using sand.
The device blends in sourced soil with a binder and sprays the mixture onto a surface. The soil solidifies as the machine gets to work to render the impressive sculptural forms.
A computer controls the robotic printer and has the ability to print in multiple directions. Aside from buildings, the printer can also create furniture, walls and other support-free sculptural shapes.
Credit goes to Inder Shergill, Anna Hulik and Petr Novikov for the development of the 3D printer. They were carefully supervised by Jordi Portell, Marta Male Alemany and Miquel Iloveras of Institute for Advanced Architecture of Catalonia.
