Interesting.
This lovely area is only 20 miles from central London, and 30 from the coast at Worthing.
Via Stane Street - the old Roman road (now A29) or a London/Brighton coaching route (A23/24).
So many wealthy people lived in the area because of these transport links - and nowadays due to nearby Gatwick and Heathrow.
A high percentage of properties are pre-Doomsday - and the green belt seems to survive well, as a result.
Many opt for a house in the Mole Valley/Surrey Hills (both AONB areas) - and a bolthole in London...
