Britain is a nation of inventors and in back gardens all over the country people are building ingenious, eccentric and brilliantly bonkers creations. From jet-propelled shopping trolleys to breakfast-making machines, the only limit is the imagination and engineering knowhow.

In this show, Sara Cox and award-winning architect Piers Taylor scour the country to find the very best backyard builders. They challenge three of them to put their skills to the test and create something truly spectacular in just ten weeks and with only £2,500. Sara and Piers then choose their favourite to win the competition. The three backyard inventors let their imaginations run wild as they attempt to build a sweet-dispensing carousel, an automated breakfast maker and a giant robot. Show less
