Andrew Flair bought the abandoned Cold War bunker back in September 2022, due to rising geopolitical unrest and the burgeoning threat of nuclear war after Russia's invasion of Ukraine. 

After a painstaking renovation to take the bunker from a wartime relic to a cosy hideout, Flair opted to flip the property and listed it for $750,000 (£594k) in June 2023. However, disaster struck and it's since been removed from the market.
