Thats where I live...

"De Beauvoir Town is home to William Lyttle, a 75-year-old retired electrical engineer. During this time Mr Lyttle has been digging a series of tunnels under his property on the corner of Mortimer Road and Stamford Road. In 2001, his tunnelling caused an 8ft hole to appear in the pavement on Stamford Road. Reports that the tunnelling had started again in 2006 were confirmed when Hackney Council found a web of tunnels and caverns, some 8m (26ft) deep, spreading up to 20m in every direction from his house.
In August 2006, the Council succeeded in getting a court order banning Mr Lyttle from his property while they carry out emergency repairs."
