Important: Additional Restrictions May Apply in The Broads Authority
The Broads Authority has 2 conservation areas. These include Halvergate Marshes BA Con Area, West Somerton. If your property is in a conservation area, some or all permitted development rights may be restricted. For example, you may need planning permission for changes that would normally be permitted, including alterations to the roof, cladding, or extensions visible from a public highway.
Check with The Broads Authority planning department before starting work to confirm whether your property is affected by any special designations.
Permitted Development Rules for a Porch
Generally permitted under Part 1, Class D of the GPDO. Porches have their own specific PD rules and are permitted provided the floor area does not exceed 3 square metres (measured externally), the height does not exceed 3m, and no part is within 2m of a boundary fronting a highway.
Conditions
- 1Floor area must not exceed 3 square metres (measured externally)
- 2Maximum height of 3m
- 3No part of the porch within 2m of any boundary fronting a highway
- 4Must be at ground level
Size and Dimension Limits
- Floor area: 3 square metres maximum (measured externally)
- Height: 3m maximum
- Must be at least 2m from any boundary fronting a highway
When Permitted Development Does Not Apply
- If the porch exceeds these limits, it is treated as an extension and must comply with Part 1, Class A rules
- Listed building consent is needed for porches on listed buildings
- May be restricted in conservation areas depending on the design
What About Building Regulations?
Building regulations approval is not usually required
A porch that is at ground level, under 30 square metres, and separated from the house by an external-quality door is normally exempt from Building Regulations. Any glazing must comply with Part K (safety glazing). Electrical work must comply with Part P.
Building regulations are separate from planning permission. Even if your project is permitted development, you may still need building regulations approval. Contact The Broads Authority building control or use an approved inspector.
How to Apply in The Broads Authority
If you need planning permission for your porch, you can apply through The Broads Authority'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 The Broads Authority. 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 is low for porches within PD limits. Porches that exceed the size limits without permission may attract enforcement, particularly if they encroach towards a highway.
