Building in Chalfont St Peter

What working in Chalfont St Peter actually involves

Chalfont St Peter is larger and busier than its neighbour, with a wide stock of post-war and inter-war houses on plots that take a serious extension comfortably.

Two storey side additions, wrap-around ground floors and loft conversions are the common brief here, usually combined with a full remodel of the existing house.

Planning

Planning policy in Chalfont St Peter

The constraints we test before design begins, not after a refusal.

  • Buckinghamshire Council determines applications, with parts of the parish inside the Chilterns National Landscape.
  • The village centre conservation area controls materials and frontage changes.
  • Green Belt surrounds the built-up area, which limits new plots and favours replacement dwellings.
  • Neighbour amenity, particularly the 45 degree test, usually sets the depth of a rear extension.
  • The Misbourne valley means drainage and ground conditions need checking early on lower plots.
