Stuart and Rosie Treasurer from the Wirral plan to transform a small bungalow from a 1960s dormer into a slick piece of 21st-century architecture. The couple decapitate the building and balance a new floating timber box on top to create five bedrooms, spending as little as possible on plumbing, electrics and insulation, but stress levels spiral when neighbours grumble at the ultra-modern creation.

Grand Designs Show Summary

Grand Designs is a Channel 4 TV series covering unusual architectural house-building projects, presented by Kevin McCloud.

The properties featured in the series vary wildly from homes underground to converted water towers, with the only common factor being that they're all rather unusual or extravagant in some way.
