An uninhabited private island in the middle of Loch Lomond has gone on sale - for the cost of a one-bedroom flat in London.

Inchconnachan, is only accessible by boat and no-one has lived there for 20 years.

It had been the holiday home of Fiona Gore, Countess of Arran, who set power boat speed records in the 1980s, reports BirminghamLive.

Planning consent and detailed architectural drawings have been obtained to replace an existing derelict bungalow with a new four-bedroom lodge and one-bedroom warden’s house, along with a boat house and pier.

The island is designated an Area of Special Scientific Interest and a Special Area of Conservation as well as being part of the Loch Lomond and the Trossachs National Park. It is surrounded by views of mountain ranges.

Wildlife lovers could watch nesting ospreys, otters and deer on the 103-acre island, which can only be accessed by a boat from Luss, Argyll and Bute.

It is on the market for offers over £500,000 - the same price as an ultra-modern one-bedroom flat near Canary Wharf in the UK capital.

Cameron Ewer for Savills said: “This is an extraordinary opportunity to acquire a beautiful and completely private, yet accessible, retreat and create a wonderful new residence there.

"For those seeking peace and seclusion, yet wanting all that this part of Scotland has to offer in the way of nature and water-based sport and activities, this is surely the ultimate prize.”

Tom Stewart-Moore for Knight Frank said: “To be able to build your own house on your own private island but yet in a very accessible and beautiful part of the country will be a dream for many and is likely to have global appeal.”
