Building in Chalfont St Giles

What working in Chalfont St Giles actually involves

Chalfont St Giles is one of the strongest locations in south Buckinghamshire for a bespoke new home, because the plots are large, the setting is genuinely rural and the ceiling prices support proper specification.

Most schemes here are replacement dwellings or major extensions, designed to answer the landscape as carefully as they answer the brief.

Planning policy in Chalfont St Giles

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

  • Buckinghamshire Council determines applications, and the village sits inside the Chilterns National Landscape.
  • The village centre is a conservation area with a number of listed buildings.
  • Green Belt covers land outside the settlement boundary, so replacement dwellings are the usual route to a new home.
  • Class Q barn conversion rights do not apply inside the national landscape, so those projects proceed by full application.
  • Chalk geology, tree cover and lanes with limited access all shape foundations, drainage and site logistics.
