Russian billionaire Peter Aven, head of Alfa-Bank, the biggest private bank in Russia, lives here. Aven has spent tens of millions of pounds turning 'Ingliston House' into a 'KGB-proof' bolt-hole. There is a two-storey octagonal security house by the entrance, a £1.5 million secure wiring system and the 8.5-acre estate is surrounded by electronic fencing. The house includes a bomb-proof 'panic room' and systems to detect sound and motion. The 18-room house is beautiful and lavish. It is 29,000 sq ft, has six bedrooms, extra suites, a gym and a wing for the saltwater pool.
