An award-winning waterfront home excavated from solid rock with its own private beach is on the market for offers over £5m.

Inverdart Boathouse, which was a 14-year labour of love for its owners and a monumental feat of engineering, has uninterrupted river and sea views.

The striking property, which has the appearance of a historic fortress, was the overall winner in the Homebuilding and Renovation awards in 2013 and recognised as a 'pioneering self build'.

The house in Kingswear, Devon, near the entrance of the River Dart, is only accessible by foot down a meandering path and steps or by boat.
