He hasn’t actually lived there for ages, it’s more a sort of office and film set for him now. He lives there when doing multiple days in a row but the family house is elsewhere. I chatted to him a year or so ago at the Late Brake Show Live in Manchester as part of a small group and he explained that he does indeed get his ideas for the tunnel checked over before doing anything and that the local Building Regs people are fully aware of what he’s doing. The neighbours are also surprisingly cool with it too! He definitely wouldn’t have got so far as he has if anything was amiss.
Oh and his DeLorean is absolutely stunning in the flesh, he drove it to the show through a rain shower and looked brilliant with the fresh rain beaded up all over the Stainless Steel body.
