Building in Amersham

What working in Amersham actually involves

Amersham gives us two very different jobs. Amersham on the Hill is largely twentieth century housing on good plots, well suited to substantial extensions and replacement dwellings. Old Amersham is a heritage environment where the work is finer grained and more sensitive.

Both sit inside the Chilterns National Landscape, so landscape impact, materials and roof form matter as much as internal planning.

Planning policy in Amersham

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

  • Buckinghamshire Council determines applications, and most of the parish falls within the Chilterns National Landscape.
  • Old Amersham is a conservation area with a large number of listed buildings, where consent and planning run together.
  • Green Belt covers land outside the settlement boundaries, so new homes generally come through replacement dwellings.
  • Chalk geology and steep valley sides affect foundations, drainage and basement viability.
  • Ridge height, chimney retention and materials are commonly the deciding points on replacement dwelling applications.

FAQs

Amersham questions, answered

Usually as a replacement dwelling rather than on a new plot, because of Green Belt policy. Volume and footprint against the original house are the tests that matter.
