Westonbury Mill house-sized cuckoo clock unveiled

A retired hydro-geologist has built a water-powered cuckoo clock the size of a small house in his back garden.

Richard Pim built the clock in Westonbury Mill Water Gardens, near Leominster, Herefordshire - his home which he opens to the public.

The clock took him three years to construct and cost him about £10,000.

"It's reasonably accurate - the cuckoo comes out on cuckoo time - but it's not necessarily Greenwich Mean Time," he said.
