Planning Permission in Clapham
Many home improvements fall under Permitted Development and don't need planning approval. But some do—especially in Conservation Areas or if you've already extended.
When you probably need planning:
- Your home is in a Conservation Area
- It's a listed building or in an AONB
- You've used your Permitted Development allowance
- The extension exceeds size limits
- It's a flat or maisonette
Our planning services:
- Pre-application advice consultations
- Full planning application preparation
- Design & Access statements
- Liaison with planning officers
- Appeal support if needed
Conservation Areas in Clapham:
Clapham Common (surrounding streets), Clapham Old Town, Abbeville Road, Larkhall, and several others.
Planning applications in Conservation Areas require additional design consideration for rooflines, materials, and scale.
