ALL he wanted was a neat new flower bed in his garden.
But retired doctor Michael Dufton got more than he bargained for when he started to dig up the lawn.
For he uncovered a real surprise from World War II - an Anderson shelter deep below ground.
The air-raid shelter had lain undiscovered in the garden of the Penistone Road house in Waterloo for more than 70 years.
Anderson Shelters were half-buried in the ground with earth heaped on top to protect families from bomb blasts.
They were made from six corrugated iron sheets bolted together at the top, with steel plates at either end, and measured 6ft 6in by 4ft 6in (1.95m by 1.35m).
Mr Dufton, who retired as a GP in Wakefield and moved to Waterloo in 2013, said: “There has always been a bit of a hump in the garden beneath the lawn and I never thought anything of it.
“But is was becoming more and more difficult for me to cut the lawn as I get older and my wife Shirley said she’d like a flower bed in there.
“I arranged with my neighbour Kim Burgon to come in and set in some railway sleepers to create the flower bed, after I had dug out a bit of the lawn.
Dr Dufton talks about his find
“I started digging and suddenly hit something metallic. I thought at first it was a fencepost support and dug around a bit more and found what looked like corrugated sheeting.
“Kim came round and he dug out a bit more and we realised we had an air-raid shelter.
“Kim had a look inside and it appears as it it has been mainly filled with bricks and rubble.
“I know many people did have them in their gardens during the war but I never thought I had one hidden away.
“It hasn’t scuppered my plans for a new flower bed but I’m leaving the shelter where it is: it’s too much of a task to get it out.”
The shelters were named after Sir John Anderson.
He came up with the design in 1938 after drawing up plans to combat German planes.
The shelters were designed to hold six people and were free to people who earned less than £250 a year - but cost £7 for others.
About 3.5m shelters were built in the UK.
