Cantilever extensions: Should you add a gravity-defying addition to your home?

Cantilever extensions are not only show-stopping structural features, but can also resolve many a practical issue. They can be used to add more space to a home on a tight plot, designed in to create a portico or space below for parking, or used to address different gradients on a sloping site, for instance.

Building an extension in this way requires a dedicated team of architects or designers, structural engineers and builders so that the execution is perfect from design to completion.
