Can I extend my detached house in Highcliffe under PD?

Detached houses in Highcliffe can extend up to 8m from the original rear wall under the Larger Home Extension scheme (Prior Approval). This provides significant scope for a large kitchen-diner or garden room without planning permission.

Are there any restrictions in Highcliffe?

Highcliffe Castle and its grounds are listed, and properties immediately around it may have additional design scrutiny. The clifftop location may require consideration of cliff stability for properties near the edge. Standard PD rules apply for most residential streets.
