A breathtaking Grade II listed former silver mine engine house which was featured on Grand Designs is on the market for £750,000 - but there's a catch.
The detached four-bedroom home sits on 3.7 acres of land - which the new buyers will own.
It appeared on the house renovation show fronted by Kevin McCloud in 2011, but the former owners never managed to finish the build.
So the new buyers will need to roll their sleeves up and pick up the loose ends.
When the home appeared on the Channel 4 show, it was owned by stonemason Adam Purchase and his wife Nicola Brennan.

They had a 12-month limit to finish the renovation but had only borrowed £100,000 from the bank.
Adam and Nicola ran out of money and missed the deadline for completion but continued to work on the home when they had time in between their day jobs.
At the time, Kevin said: “The exterior is a testament to Adam’s skill and dedication.”

But later added: “Adam and Nicola are a long way from moving in. It may not be finished but it is tantalisingly close.”
The lay out of the house is particularly unique and stretches over four floors.
The former silver mine starts with an entrance hall and kitchen on the ground floor.

This level also has a shower room and bedroom, for guests.
One level up on the first floor there is another bedroom and bathroom, and then the next floor is where the sitting room is located.
The master bedroom with an en-suite is located on the third floor.
And then in the basement there's another bedroom and another en-suite bathroom.

There is a huge wooden balcony that leads off from the third floor.
Across from the silver mine is an engine house, which has planning permission for conversion.
There is also a garden area and paddock - perfect for a green fingered new owner.
Kevin has spoken recently about how the designs of homes are changing.
