Local detail
Beaconsfield, Gerrards Cross, Chalfont St Giles, Amersham (the former South Bucks and Chiltern districts) sit at the top end. Aylesbury Vale and Wycombe town centres lower; Wendover and Tring-adjacent villages premium for the train.
Buckinghamshire Council became unitary on 1 April 2020, absorbing Aylesbury Vale, Chiltern, South Bucks, and Wycombe district councils. One planning service across the county; legacy Local Plan policies from the predecessor districts still control until the unitary Local Plan is fully adopted.
The Chilterns National Landscape covers much of south Bucks and along the AONB ridge into Aylesbury Vale. Replacement-dwelling consent in the AONB requires careful design and materials work; pre-app strongly recommended.
