Architects in Buckinghamshire
From Gerrards Cross and Beaconsfield to Amersham and High Wycombe, south Buckinghamshire's larger houses suit ambitious extensions, but Green Belt and the Chilterns shape what is approved.

In south Buckinghamshire we mostly draw extensions, loft conversions and replacement houses. Green Belt and the Chilterns National Landscape both affect what the council will accept, so we check the site's designations and planning history before design starts.
While the new county-wide Local Plan is prepared, applications are still decided against the policies of the former district councils.

Buckinghamshire Council is preparing a single Local Plan to 2045. The council expects to submit it for examination by 31 December 2026, with hearings in 2027; until then, the plans of the former district councils apply.
