Made from prefabricated panels, a Surefast building can be put together in just 10 hours with “a crowbar, a spanner and, oh, a crane”, says Dr Tolloczko.

With such swift building times, Surefast could perhaps be a cheap answer to the housing shortage affecting many parts of the UK. "You can clad the outside to look like brick. I wouldn’t have a problem living in one," he says.
