Planning in Camden
Start with the rules for your property, then compare projects like yours. London Borough of Camden's planning register lets you check a neighbouring scheme's drawings, decision notice and conditions. A nearby approval can help you understand the council's approach, but different site constraints can change the outcome.
For a home in a conservation area, read the relevant conservation area appraisal alongside the Local Plan. For a listed building, check both planning permission and listed building consent. Use the council's current records to confirm the boundary and any Article 4 direction.
Planning issues to check before you apply
Use your drawings to show how the proposal addresses the site and the council's policies:
- The extension's height, depth and position relative to neighbouring windows and boundaries.
- Privacy, daylight and the amount of usable outdoor space left after the work.
- Materials, roof form and any effect on the character of a conservation area or listed building.
- Protected trees and any site-specific flood or basement constraints.
- Conditions on earlier permissions that may restrict what you can build.
This is a checklist for the proposal, not a ranking of local refusal reasons. The council's decision notice explains the reasons for an individual refusal.

Questions about planning in Camden
Do I need planning permission for my project in Camden?
Some house extensions, loft conversions and outbuildings can use permitted development rights in Camden, but size alone does not establish eligibility. Check the property type, previous extensions, planning conditions and the rules for the proposed work. Householder rights do not apply to flats. Conservation areas and Article 4 directions restrict particular rights; they do not automatically require an application for every change. Listed building consent is a separate requirement for works affecting a listed building's special interest.
How long does Camden Council take to decide a planning application?
The usual statutory period for a householder planning application is 8 weeks from a valid application, unless a longer period is agreed. This is a decision period, not a measured average for Camden. Preparing drawings and validation take additional time. Larger home extension prior approval has a 42-day procedure; other prior approval routes have different periods.
What is the planning approval rate in Camden?
It depends on the project type. 94% of 1,925 decided single-storey rear extension applications in Camden were approved. 84% of 883 decided loft conversion and dormer applications in Camden were approved. Checked against 20.6 million UK planning applications on file across 420 planning authorities. Approval rates from 2,343,419 decisions we classified across 181 councils in England. Every project type is on the Camden approval rates page.
Are there Article 4 directions in Camden?
Check London Borough of Camden's published directions for your address and proposed work. An Article 4 direction removes only the permitted development rights specified in that direction, within its defined area. Its map, wording and effective date matter. It does not mean every alteration needs a full planning application.
