An 18th century folly which was converted into a luxury home and featured on TV property show Grand Designs is on sale for £2 million. Kemeys Folly, in Langstone, near Newport in South Wales, starred in the popular Channel 4 programme six years ago when it was converted into a six-bedroom luxury house - and now owners Sarah and Dean Berry have put the unusual property up for sale. The ambitious project saw the couple combine the painstaking restoration of a castellated 18th Century hunting lodge with the construction of a state of-the-art glass extension.

Owners Sarah and Dean Berry have now put the unusual Grade II listed six-bedroom home up for sale for £1,999,950 . The ambitious project saw the couple combine the painstaking restoration of the old hunting lodge with a state of-the-art glass extension . The couple paid £830,000 for the tower in 2005, which was being sold by a couple who had quickly realised that there was far too much work to do, and put it back on the market. Work on Kemeys started in January 2007 and over the next year an old extension was demolished, the outside of the tower was re-pointed and the inside was stripped as much as the building's listed status would allow. Now, The Grade II listed home boasts six bedrooms, five of which have en-suite bathrooms - and including a master bedroom which takes up a whole floor of the tower and opens up on to its own roof terrace. Sitting in 23 acres of land the property also boasts a cinema room in the older part of the building and outside there is a large pool house with swimming pool and changing facilities. The folly also has four stables which back directly onto a paddock. The glass extension takes full advantage of the stunning hilltop location - on a clear day you can see 11 counties as well as the two Severn road bridges and the Bristol Channel. The owners say the surrounding woodland is perfect for long walks, and which features lots of wildlife, including deer. Something of a local landmark, the original building was a hunting lodge dating back to the 1700s and was at one point owned by the Sheriff of Monmouth. The folly is situated in the heart of the Usk Valley in South Wales and has a roof terrace which enjoys this view over the  countryside . The house boasts a master bedroom and en suite which takes up a whole floor of the tower and opens up on to its own roof terrace . It was struck by lightning in 1890, rebuilt as a home in the early 1900s and was eventually converted into a house for the Sheriff of Monmouth . The couple paid £830,000 for the folly in 2005 and spent hundreds of thousands of pounds renovating it and bringing it up to scratch . Mrs Berry said: 'We bought it with a view to carrying out significant work on it, renovating the tower and extending it. 'It was one of those love at first sight moments. We were in London at the time but knew we wanted to move back here to where we grew up. 'Neither of us even knew it existed but when we saw it we wanted it. It was just outstanding.' The couple spent a huge amount of time with planners to agree on a concept for the home that everyone was happy with. She said: 'The idea was to keep the original features of the main building, such as the beautiful exposed stonework, but not to mimic what was already there in the extension. 'We wanted to create new sections that helped to tell the story of the building through the years and were an expression of the 21st century. 'Living here has been such fun.' A former hunting lodge, the folly was built in 1712 by local landowner George Kemeys. It was struck by lightning in the late 1890s, partially rebuilt as a home in the early 1900s and converted into a house for TE Watson, the High Sheriff of Monmouthshire. The couple are selling as they are downsizing but say: 'Whoever takes Kemeys Folly on now is going to enjoy such an amazing life here.' The house is for sale for £1,999,950 with Chewton Rose.
