Two second world war Nissen huts will be dismantled and transported to a new home after permission was granted to build a supermarket on their existing site.

Morrison's will bear the cost of the work involved in removing the structures from Postmill Close in Wymondham before it is cleared to make way for a new store.

Work is expected to begin on Monday and take about four men four days to take each hut apart before they are transported to the 93rd Bombardment Group Museum in Hardwick.

Bomb group association member Derek Fulton said he believed the huts could have originally been used as accommodation at Hethel during the second world war. They would then have been moved in the 1950s or 60s to house Semmence coaches on the Wymondham site.

'They came as a flatpack and they weren't designed to last as long as they have done,' he said. 'There aren't very many left because they were treated with disregard, but when we heard about these we decided it was outside of our capabilities to dismantle them in the time span so Morrisons said they would do it.'

The huts were put together with steel hoops which were encased in corrugated iron. To take them apart, scaffolding will be used to get to the outside before cutting the head off each fixing, removing the sheets and taking apart the steel structure.

Mr Fulton added that they could be reasembled or their parts used to repair existing Nissen huts.

'They're part of our history,' he said. 'If we find they were used for accommodation they could have housed an 18-year-old in a space created by the loss of a crew that never came back, so there's as much history in a building like this as a brick building. Wherever possible with things like this, we try to save them rather than scrap them. I think these have lasted so well because they were used after the war.'

Workmen are currently clearing the site with the build expected to start in the new year.

A Morrison's spokesman said: 'We are delighted to assist the 93rd Bomb Group Museum with preserving these structures of such historical interest. It is great news that part of Norfolk's world war two legacy can live on and that the huts can add to the existing collection at the Hardwick Airfield Museum.'
