Conservation areas

There are 56 conservation areas in Westminster. They are designated by us for their 'special architectural and historic interest.'

Within conservation areas, certain additional planning controls apply. You will need to apply for planning permission for demolition and for some alterations or extensions that don't need permission outside a conservation area. See more information on permitted developments rights

You must give us 6 weeks notice before any work is carried out to prune or fell a tree in a conservation area. See more information on trees.

The conservation area online map can be used to see what areas are affected.

Conservation area guidance and audits

We prepare studies known as conservation area audits which provide a description of the special qualities, character and appearance of each conservation area. Audits are adopted either as Supplementary Planning Documents or Supplementary Planning Guidance

See maps and information on each conservation area and a list adopted and draft audits.

See the guidance in our Development and Demolition in Conservation Areas SPG.
