Permitted Development Rules for a Garden Shed
Generally permitted under Part 1, Class E of the GPDO. Outbuildings are permitted provided they are for purposes incidental to the enjoyment of the dwelling, are not forward of the principal elevation, and comply with height and area limits.
Conditions
- 1Must be for purposes incidental to the enjoyment of the dwelling
- 2Must not be forward of the principal elevation fronting a highway
- 3Maximum height 2.5m if within 2m of a boundary
- 4Maximum height 4m (dual-pitch roof) or 3m (any other roof) if more than 2m from a boundary
- 5Must not cover more than half the curtilage (combined with all other outbuildings and extensions)
Size and Dimension Limits
- Height within 2m of boundary: 2.5m maximum
- Height elsewhere: 4m (dual pitch) or 3m (other roofs)
- No single building footprint limit, but total must not exceed 50% of curtilage
When Permitted Development Does Not Apply
- In designated areas (conservation areas, AONB, etc.), outbuildings to the side of the house are not permitted development
- In designated areas, total outbuilding area beyond 10 square metres requires planning permission
- Cannot be used for sleeping accommodation (residential use)
- Must not be a separate self-contained dwelling
What About Building Regulations?
Building regulations approval is not usually required
Building Regulations do not normally apply to detached single-storey outbuildings under 15 square metres with no sleeping accommodation. Between 15 and 30 square metres, the building must be at least 1m from any boundary or be constructed of non-combustible materials. Over 30 square metres, Building Regulations apply.
Building regulations are separate from planning permission. Even if your project is permitted development, you may still need building regulations approval. Contact Bromley building control or use an approved inspector.
How to Apply in Bromley
If you need planning permission for your garden shed, you can apply through Bromley's planning department or via the national Planning Portal.
If your project is permitted development and you want written confirmation, you can apply for a Lawful Development Certificate (LDC) from Bromley. This provides proof that your project does not need planning permission, which can be helpful when selling your property.
What Happens If I Build Without Permission?
Enforcement is unlikely for modest sheds within PD limits. Oversized or over-height sheds may attract complaints from neighbours, leading to enforcement investigation. The council can require removal if the shed breaches PD conditions.
