Set to be constructed in Coachella Valley, home to the world-famous music festival, 15 homes are being built using 3D-printing, robotics and automation. The high tech process produces 10 times less waste than traditional building methods, according to construction technology company, Mighty Buildings. It claims all of the energy needs for these properties will be provided by solar power. Homeowners will also have the option of installing Tesla Powerwall batteries alongside electric vehicle charging points. With this ethos of sustainability in mind, the buildings have been designed to have minimal environmental impact.
