LEIGH (pronounced Lie), is very much a dormitory village. It has a huge green canopied with conker trees, and traditional tile-hung and weatherboarded Kentish houses. There is a post office stores and a hairdresser. The primary school flourishes, and organised activities range from the mothers-and-toddlers group to the cricket club. Leigh is popular with London solicitors and bankers, which explains the arrival of a new development of executive houses. A five-bedroom period property with four reception rooms, granny annexe, tennis court and swimming pool would cost £1m or more; a three-bedroom semi £280,000.
