When Dale had the idea to cover their roof with Astro Turf, he knew it was going to be tricky.
"Even the grass companies I rang up for advice said, 'No, you can’t do it on a roof.' I showed them!" he says with a laugh.

"We put it up using contact adhesive. You roll it out on the roof and then on the back of the grass as well," he explains.

Mental it may be, but it looks amazing. Will it be enough to secure them a Bonus House Room Reveal win?
