Renovation of Ruined Castle Selected Britain's Best Building

"Architecture awards are not often given to structures where the roof has caved in and walls have crumbled, but nor are many ruins treated with the care and attention lavished by Witherford Watson Mann architects, whose striking £2.5m intervention has seen the building converted into a beguiling holiday home for the Landmark Trust," writes Oliver Wainwright.

"Stitching a series of brick and timber walls into the ravaged shell, the architects have deftly intertwined a forcefully modern approach with a strong sense of the original ruin, crafting a layered sequence of spaces that celebrate the building's 800 years of history."

Perhaps the best part: The castle is available for rent for as little as £21 a night per person for the cheapest weekends.
