Do I Need Planning Permission for a Shed Base?
If you're planning to install a garden shed, one of the most common questions is whether you need planning permission for the base. In most cases, the answer is no — but there are important rules you must follow.
This guide explains when a shed base is permitted development, when permission is required, and how to stay compliant with UK planning regulations.

Do You Need Planning Permission for a Shed Base?
In most residential gardens, a shed base does not require planning permission as long as it complies with permitted development rules.
- The base must be incidental to the enjoyment of the house
- It must not be used as living accommodation
- The overall structure must stay within height limits
This applies to concrete bases, paving slabs, and timber bases.
When Planning Permission IS Required
You may need planning permission for a shed base if:
- The base supports a structure taller than permitted development allows
- The shed is placed forward of the principal elevation of your home
- The property is listed or in a conservation area
- The base covers more than 50% of your garden
You can confirm rules via the official UK Planning Portal: Planning Permission for Outbuildings
What Type of Shed Base Is Best?
Most homeowners choose one of the following bases:
- Concrete slab bases (most durable)
- Paving slab bases
- Timber or plastic shed base systems
Heavy structures such as heavy duty sheds usually require a concrete base for stability.
Choosing the Right Shed for Your Garden
The right shed size and base combination ensures compliance and long-term durability.
- Small Sheds – ideal for compact gardens
- Medium Sheds – great for storage & workshops
- Large Sheds – may require extra planning checks
