Nano House presents the latest and most exciting solutions for houses where space is at a premium, nature must be preserved or accommodation created for those who need it most. In our growing cities, space is at a premium. In the countryside, we want to preserve the landscape and build as 'lightly' as possible and in impoverished parts of the world the need for sustainable, economical shelter is stronger than ever. At the same time, digital design tools, eco-materials and new prefabrication technologies have all led to an explosion in innovative ideas for our domestic spaces. Today's challenge for architects and designers is to produce small-scale habitats that are more ecological, flexible and efficient, as well as adhering to modern standards of style and comfort.
