Creative DIYer Colin Furze is all about the surprises. He lives in a normal house, on a normal street and out back sits the most average garden you could possibly imagine. But right underneath that underwhelming garden sits a hidden underground bunker. The entrance lies hidden as well inside a shed in the far back of the yard. Enter the shed and no door is instantly obvious. After an old barbecue is moved and a dirty rug pulled up, a trap door is finally revealed and the surprise awaits just inside!
