A grandfather in England gave his wife the surprise of her life after winning a $6 million mansion in a competition she didn't even know he'd entered.

Ian Roberts, 66, won the keys to the spectacular six-bedroom country home in Yorkshire as well as over $668,000 (£500,000) in cash after spending just over $33 (£25) as part of his Omaze subscription.

Ian, who currently lives in Warwickshire in the West Midlands, couldn't believe it when he was told he'd won the latest Omaze Million Pound House Draw. He described it as their “very own Downton Abbey,” per a press release obtained by PEOPLE.
