If your development site is in a conservation area, you will generally need 'planning permission for relevant demolition in a conservation area' (also commonly known as 'conservation area consent') to do the following:
- Demolish a building with a volume of 115 cubic metres or more.
- To demolish any gate, fence, wall or other means of enclosure with:
- a height of one metre or more if next to a highway (including a public footpath or bridleway), waterway or open space; or
- a height of two metres or more elsewhere.
Please note: There are some exemptions to these general requirements.
You can view further details in the official government guidance or discuss the matter with your local planning authority.
