A barn conversion for sale in Cornwall comes with a special secret at the bottom of the garden – a 50-person air raid shelter.

The property at Trevellas, between Perranporth and St Agnes, has been put on the market and it’s not like every home.

While barn conversions are becoming increasingly common in the Duchy, not all of them have an air raid shelter capable of fitting 50 people.

And the military connections don’t just end there. The site was once home to RAF barracks in Nissen huts, signs of which can also be seen in the form of concrete pads, and two tumbledown blocks of washing facilities.

It’s also close to Perranporth Airfield, where during the Second World War the RAF had a Spitfire base.

The main property is a former barn converted into a two-bedroom home, described as “contemporary and minimalist.”

Also part of the package is a separate one-bed barn conversion annexe, a former tractor shed now used as a studio and workshop, a polytunnel and ground-mounted solar panels, all within a large paddock.

The site is for sale with Clive Pearce Property in Truro with a guide price of £799,950.

A spokesperson for the estate agents said: “As a permanent home, or home from home, there is a great deal of potential for its new owners to explore – to generate an ongoing income by renting the annexe, to extend the main house, to convert the tractor shed to accommodation or stabling, and to make a real feature of the air raid shelter.

“There are so many possibilities! All subject to the relevant consents, of course.”

The main barn is configured as a large open plan living/kitchen/dining space with an ensuite bedroom at either end.

Both this and the annexe have bi-fold doors and overlook the gravelled gardens and paddock.

A 4kw solar array contributes to the property’s energy requirements, while a wood-burning stove heats the tractor shed.

It also comes with a wetsuit hangout and outdoor shower for after those visits to the north Cornwall coast.
