Recently, Max and Daniel Zielinski have been awarded the best architects in the UK and they have been praised for many of their creations, including a very special project for a modular building on the moon. They have stated that they have been working with NASA to build a simple modular living unit by using 3D printing. The unit would be built with materials that can be found on the moon, such as moon dust which would be 3D printed.
