Important: Additional Restrictions May Apply in Knowsley
Knowsley has conservation areas. 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 Knowsley planning department before starting work to confirm whether your property is affected by any special designations.
Permitted Development Rules for a Hard Standing
Whether hard standing is PD depends on the surface type and location. Permeable surfaces (gravel, porous paving, permeable block paving) are PD under Part 1, Class F. Non-permeable surfaces over 5 square metres require planning permission unless they drain to a permeable area within the property boundary. Rear garden hard standing is generally PD.
Conditions
- 1Permeable surfaces are PD regardless of size
- 2Rear garden hard standing is generally PD
- 3Front garden: non-permeable surfaces over 5 square metres require PP unless draining to a permeable area
- 4Must not significantly raise the ground level (over 300mm becomes a raised platform)
Size and Dimension Limits
- No size limit for permeable surfaces
- Non-permeable front surfaces: 5 square metres maximum without drainage provision
When Permitted Development Does Not Apply
- Front garden non-permeable surfaces over 5 square metres without proper drainage need PP
- In designated areas, additional restrictions may apply
- Consider the impact on drainage and flooding for neighbouring properties
- A dropped kerb is a separate application if vehicular access is needed
What About Building Regulations?
Building regulations approval is not usually required
Building Regulations do not apply to hard standing. Adequate drainage should be provided to prevent surface water flooding. This is enforced through the planning system and environmental regulations rather than Building Regulations.
Building regulations are separate from planning permission. Even if your project is permitted development, you may still need building regulations approval. Contact Knowsley building control or use an approved inspector.
How to Apply in Knowsley
If you need planning permission for your hard standing, you can apply through Knowsley'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 Knowsley. 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?
Low to moderate risk depending on the surface type, size, and location. Non-permeable front garden surfaces are the main enforcement concern. The most common practical consequence is an issue raised during property sales rather than proactive council enforcement.
