Permitted Development Rules for a Patio or Paved Area
Generally permitted. Laying a patio or hard surface in the rear garden is permitted development as an improvement within the curtilage. Front garden hard surfaces are PD if the surface is permeable or drains to a permeable area within the curtilage.
Conditions
- 1Rear garden patios are generally PD without specific conditions
- 2Front garden: must use permeable paving or drain to a permeable area within the garden
- 3Must not significantly raise the ground level (over 300mm becomes a raised platform)
- 4Good drainage practice to prevent flooding and waterlogging
Size and Dimension Limits
- No specific size limit for rear garden patios
- Front garden: non-permeable surfaces over 5 square metres require PP if not draining to a permeable area
When Permitted Development Does Not Apply
- Front garden non-permeable paving over 5 square metres requires planning permission (since 2008)
- Listed buildings may require consent for changes within their curtilage
- Raised patios over 300mm above ground level may need PP (treated as raised platforms)
What About Building Regulations?
Building regulations approval is not usually required
Building Regulations do not apply to standard patios. There are no structural, thermal, or fire safety requirements. Drainage should be managed to prevent water pooling against the house (maintaining the damp proof course level).
Building regulations are separate from planning permission. Even if your project is permitted development, you may still need building regulations approval. Contact Stevenage building control or use an approved inspector.
How to Apply in Stevenage
If you need planning permission for your patio or paved area, you can apply through Stevenage'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 Stevenage. 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?
Very low risk for rear garden patios. Front garden non-permeable paving over 5 square metres without proper drainage is an enforcement risk, though enforcement is relatively uncommon in practice.
