May had around 1,000 volunteers to help him build the house
A two-storey Lego house created by Top Gear and Toy Stories presenter James May faces demolition after plans for Legoland to buy it fell through.
The house will be demolished on Tuesday if a new owner cannot be found in time.
It will cost about £50,000 to dismantle and reassemble. Top Gear's website has set up a Facebook page in an attempt to find a buyer.
Legoland now say it is too expensive for them to move it. The house was made for BBC Two series Toy Stories.
The house was built by about 1,000 volunteers and currently stands in Denbies Wine Estate in Dorking, Surrey - but now the vineyard needs the land back to harvest its grapes.
The Legoland theme park is in Windsor, Berkshire.
"Knocking it down is just wrong on every level. It's a really lovely thing - it would break the hearts of the 1,000 people who worked like dogs to build it," May told the Mail on Sunday.
The house even has its own Lego cat.
Martin Williams, sales and marketing director of Legoland Windsor, explained to the BBC why they could not proceed with the deal.
"We are so disappointed that we are unable to take this amazing Lego construction.
We have looked at various options but unfortunately due to the costs and logistics of moving and re-building the house at Legoland, we are unable to proceed with this project."
James May's Toy Stories takes a look back at the some of the UK's best loved toys and each week the presenter faces a new challenge.
Tasks so far have included constructing the Lego house and attempting to build a full-size model Spitfire.
