Each of these outstanding homes, all featured on Grand Designs, appear to defy physics with overhanging structural elements.

A cantilever, if you’re unfamiliar with the term, refers to a beam, or in the case of Grand Designs an extension from a home, supported from only one end, creating an overhanging structure.
It’s a common architectural practice, which has been employed in plenty, if not some of the most iconic, of Grand Designs homes.
Here, the Grand Designs magazines team choose some of their favourite examples from the show.
Shipping container home, County Derry
When building a new home on his parent's land in County Derry, architect Patrick Bradley turned to shipping containers for a low-cost build method. By arranging the two containers at right angles from each other, the upper storey cantilevers out in both directions, culminating in a balcont, surrounded by steel fins to avoid too much solar gain into the main living space.
Periscope House, Norfolk

Natasha Cargill's Grand Design is most recognisable for its symmetrical cedar-clad boxes - each offer balconies cantilevered from the main house, with views out over the River Tud valley.

Glass house, Brixton

Carl Turner and Mary Martin's self build project in Brixton consists of a stack of three cantilevered glass-clad rectangles. The build, which takes up the entirety of the plot they sub-divided from the original house on the site, makes an efficient use of space, allowing for a small wildflower garden on the second storey cantilever to bring so much needed greenery to the space.
Flint House, Waddesdon Manor

Flint House, belonging to Baron Rothschild, made for a worthy winner of 2015's House of the Year. Perhaps best recognised for its stepped profile, like a geological excavation, it also features dynamic cantilever sections, which soften the monolithic nature of the home.
