No matter how appealing the idea of blasting off from the planet to live in a space pod might feel at the moment, putting your feet up in the outer depths of the universe is a few years off yet. But has Beijing created the home of the (slightly nearer) future? The world's first entirely 3D-printed house was unveiled in the Chinese capital a few weeks ago. The two-storey, 400-square-metre building is the first to have been printed in one piece, and took just six-and-a-half weeks to make in Beijing's Tongzhou district. The printer constructed the house, layer by layer, before getting in a team of decorators to add finishing touches. Architects working on the project suggest that this could be the start of a building revolution. It might even put paid to London's lack of affordable accommodation. House about that then?
