Advertisement A £48million mansion nestled in the hills above the French Riviera must be demolished after a court ruling brought a 15-year legal standoff to an end. Property tycoon Patrick Diter built a 32,000 sq ft Italianate palace, dubbed 'Chateau Diter', on the site of what was once a modest 2,000 sq ft farmhouse without first obtaining planning permission. The building work started in 2005 and in 2009 a group of disgruntled neighbours, led by British millionaires Stephen and Caroline Butt, took Mr Diter to court, deciding the 'building frenzy had to stop'. In 2015 an appeal court in Aix-en-Provence ruled that the chateau must be demolished. Only the small original house was spared.
