Grand Designs S17E08 - The Wirral: Floating Timber House

How do you turn your small bungalow from a 1960s dormer into a generous 21st-century piece of slick architecture, all for £175k? Stuart and Rosie Treasurer from the Wirral plan to decapitate their bungalow - cutting the roof off to leave just the walls - then balance a big new floating timber box on top, containing five bedrooms. To keep costs down, they take on the plumbing and electrics themselves, spend as little as they can on insulation, and leave elements of the building unfinished. The hope is to get a stylish industrial look in the process. But the stress levels spiral when their neighbours grumble about the ultra-modern wooden box going up in the middle of their traditional suburb.
