Sunk by our trendy iceberg home: Couple who dug into their basement to extend reveal how their house literally fell APART, sparking a series of ruinous legal battles - and they're still paying a mortgage on a hole in the groundIn November 2012, Jacquie Hale and Ed Goldswain (inset with their two sons) had planned to use their savings to extend their £345,000 ground-floor flat into the basement of their property in Finchley, north London. But the whole property suffered a terrifying structural collapse - effectively splitting in half - following a botched basement conversion (left and top right). Several years later, there is still a large crater in the centre of an otherwise attractive terrace of houses where their property once stood (bottom right) and the family are still mired in a legal and financial nightmare.
