As part of his BBC series James May's Toy Stories, he plans to build a two-storey house in the middle of Denbies Wine Estate in Dorking.
May will be hosting a building day on Saturday, August 1, when members of the public can help him with the challenge.
The millions of bricks came all the way from the Czech Republic. The house will be life-size with a staircase, toilet and shower.
I would live there. And by live there I mean come home drunk, pass out on the floor, and wake up with LEGO marks all over my face. Then maybe some puking action.

Thanks to Kieren, who built an entire planet out of LEGO and then ran through it like a leaf pile.
