A House Built Inside an Underground Reservoir

A couple have told how they spent three years creating one of Britain’s most unusual properties – by converting a former underground reservoir. Civil engineer Robert Hardy and his wife Ann began the mammoth project after falling in love with a 6,500 sq ft site at the center of a hill in Sidmouth, Devon. The decommissioned reservoir resembled a concrete drum, and had been lying unused for five years when they bought it from South West Water in 2008.
