A house in Cornwall, England was inches away from disaster this week, after a 300ft deep sinkhole opened up in the garden. The huge cavern was discovered when builders were drilling into the patio of the empty bungalow. The area of Scorrier has a history of mining and it is believed the workers may have disturbed an old mineshaft. Drone footage shows the incredible depth of the sinkhole and Michael Thomas, who captured the footage, added: ‘This shaft is truly massive and is approximately 300ft to water and god knows how deep from there!’ We’re guessing there might not be too much interest when the empty bungalow does go on the market!
