The tiny home your children may be living in one day
Engineers have developed a miniature home which they say could provide affordable accommodation for people, while at the same time help them to live in a sustainable way.
The carbon neutral QB2, which measures three metres by four metres, was designed by Dr Mike Page from the University of Hertfordshire, and is said to be suitable for one person or a couple.
It uses mezzanine levels, clever storage, large windows and fewer walls to give a sense of space.
Dr Page says he incorporated all the latest green technology to show how people could live in a carbon neutral way without having to make sacrifices.
The homes could be stacked and are seen as a possible solution to affordable housing in expensive city or countryside locations.
Costing the Earth's Tom Heap - who is six feet two inches tall - was the first person to test it out overnight and took us on a tour.
