The Quieter Millionaires

If you want to live in London, somewhere truly exclusive and understated, then head over to Holland Park and Wycombe Square. This development of neo-Georgian homes (built around 20 years ago) has apparently the accolade of being the most expensive residential street with an average (!) price of £5.4M. If you want to have a look around, I've found one for sale at just over £10M.
