A stately-home has been transported back to its condition in the Second World War after six months of painstaking restoration . Today , the hard work paid off as the time-capsule building was re-opened by The Great British Bake-off 's Mary Berry . Mary opened the Warwickshire stately home to celebrate the house 's incredible transformation and to mark the seventieth anniversary of the end of the conflict . Mary Berry re-opened Upton House in Warwickshire that has been restored to the state it was in 1939 . Upton House , a National Trust property located in the parish of Ratley and Upton , has been transported back in time to 1939 , when London-based bank M.Samuel & Co moved into the building as they were at risk of having their premises demolished in the London Blitz . The house became one of only two country house banks during the war , the other being the Bank of England . Mary , 80 , opened the newly-refurbished house after a team of 80 volunteers went to extraordinary lengths to recreate the manor , even sourcing two rolls of 75-year-old toilet paper . Other fastidious details include WW2 toothpaste , oil from that era that would have been used in typewriters and the team even made lipstick from boiled beetroot , which was common practice at the time . London-based bank M.Samuel & Co moved into the property as they were at risk of having their own building demolished in the London Blitz . The house took six months of painstaking restoration to restore it to its former state . Rachael O'Connor-Boyd , head of Museum Collections Manager at Warwickshire County Council who oversaw the project at the National Trust property , said it was essential to include the tiny , everyday objects in the faithful recreation of the house , which took six months . The 37-year-old said : 'We do need the ephemeral details like toilet paper and I got a bit obsessed with 1940s toilet paper . 'We searched high and low and eventually some toilet paper came up on eBay . We did eventually get two rolls of wartime loo roll that I was very happy with . ' Mary Berry opened the stately home to celebrate the house 's incredible transformation and to mark the seventieth anniversary of the end of the Second World War . Although Rachael was able to get hold of the hard-to-find product she admits that even when they were available in 1939 , not many people would have had access to it . 'It 's very rare as , at the time , people would generally not have used it , they would have used scraps of paper or even newspaper in some households . ' This level of intricate detail has permeated every aspect of the recreation of Upton House . Sourcing loo rolls : Among the objects bought were two rolls of 75-year-old toilet tissue costing £30 each . Many of the props were sourced online but the team had also received donations from collectors . The bathrooms are stocked with toothpaste and toothbrushes from the era . Even pens and pencils have been found from the 1940s to fill the desks in the house . Rachael says that a lot of the material has been discovered online through six months of research , but they have also been fortunate enough to receive invaluable donations . She said : 'There are some things that you do not know that you want and then when you get them they are perfect . Rachael O'Connor-Boyd who oversaw the project said it was important to gather everyday items . Girl of her time : Mary Berry would have been just four-years-old in 1939 . 'One instance would be 1940s tea that came in a cardboard box in wrapped up packets with hand written notes . They had been in somebody 's attic for 70 years and was in a pristine condition . ' A lot of the items we received were from the kindness of strangers . ' In order to create a high level of accuracy the team had to be prepared to spend more than one would usually on household items . The toilet paper alone cost £60 for the two rolls . Rachael says that the project would n't have been possible without people who had decided to preserve such items . 'There are some glorious people out there that keep everything and if it were n't for people who kept things in their loft or their attics , we would n't have these objects and that window into a world that 's gone . ' She said finding the everyday items for the house was vital to faithfully recreate the home 's wartime story . She added : ' I honed onto things like the toilet paper because it 's ordinary peoples ' lives and that 's important to our story because it 's a mansion where for that period during the war , ordinary people took over this extraordinary place .
