Campervan and Olympic Dome

On the sunny coast of Cornwall, world-class adaptive surfer Pegleg plans a unique extension to his VW campervan, transforming his home on wheels by building a new cabin from scratch. In Pembrokeshire, Martin and Carol-Anne have an out-of-this-world scheme to turn a dome used to house an electricity generator at the London Olympics into an extra-terrestrial glamping pod in the garden. On the coast of western Japan, George visits an earthquake-resistant house made from glass. And George looks at aluminium panels as a new kind of leafy canopy for his and Will Hardie's spectacular tree house.
