What are the biggest changes to our homes going to be by the year 2020? Will the house of the future be environmentally friendly? What new materials might they be manufactured from, and what new technology will we be living with?
Tomorrow's World's Judith Hann and Howard Stableford enlist the help of futurist Christine MacNulty and glass technology specialist David Button to predict how we might be living in 30 years time, and make a mock-up house in the studio.
