Permitted Development Rules for a General Outbuilding
Generally permitted under Part 1, Class E of the GPDO. Outbuildings must be for purposes incidental to the enjoyment of the dwelling and must comply with height, position, 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 (all outbuildings and extensions combined)
Size and Dimension Limits
- Height within 2m of boundary: 2.5m maximum
- Height elsewhere: 4m (dual pitch) or 3m (other roofs)
- No single footprint limit, but cumulative total must not exceed 50% of curtilage
When Permitted Development Does Not Apply
- In designated areas, outbuildings to the side of the house are not PD
- In designated areas, total outbuilding area exceeding 10 square metres requires PP
- Must not be used as sleeping accommodation or a separate dwelling
- Total cumulative outbuilding footprint (including sheds, summer houses, etc.) counts towards the 50% limit
What About Building Regulations?
Building regulations approval is not usually required
Under 15 square metres with no sleeping accommodation: normally exempt. Between 15 and 30 square metres: must be at least 1m from any boundary or constructed of substantially non-combustible materials. Over 30 square metres: Building Regulations apply in full.
Building regulations are separate from planning permission. Even if your project is permitted development, you may still need building regulations approval. Contact Kingston upon Hull building control or use an approved inspector.
How to Apply in Kingston upon Hull
If you need planning permission for your general outbuilding, you can apply through Kingston upon Hull'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 Kingston upon Hull. 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 risk increases with the size and use of the outbuilding. Large outbuildings that dominate the garden or are used for residential or commercial purposes attract enforcement. Neighbours' complaints are a common trigger for council investigation.
