Top Gear co-presenter James May is looking for volunteers to help him build a new house – entirely out of Lego bricks.

As part of his new series James May’s Toy Stories, he is planning to construct a two-storey dwelling in the middle of the Denbies Wine Estate in Dorking, Surrey.

And members of the public will be invited to help him on a ‘building day’ next weekend.

The house – which will reportedly comprise three million Lego bricks, will be life-sized with a staircase, shower and toilet – and May says he plans to live in it for a few days once it is complete.

“I’ve got a man working on a flushing Lego lavatory,” he said. “We think it’s possible.

“Things like power supply, sanitation and plumbing coming into the house are as they could be for a real building. Everything within my Lego house must as far as possible be Lego.”

The challenge comes just two months after May built a garden entirely out of Plasticine, which won an award at London’s Chelsea Flower Show.
