Important: Additional Restrictions May Apply in Shropshire
Shropshire has 121 conservation areas. These include Acton Burnell, Alberbury, Albrighton, Albrighton (Station Road), All Stretton, Alveley. 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.
Shropshire has Article 4 directions in force. Article 4 directions remove specific permitted development rights in defined areas. If your property is covered by an Article 4 direction, you may need planning permission for work that would normally be permitted. Contact Shropshire planning department to check whether an Article 4 direction applies to your property.
Check with Shropshire planning department before starting work to confirm whether your property is affected by any special designations.
Permitted Development Rules for a Garden Room
Generally permitted under Part 1, Class E as an outbuilding. Garden rooms follow the same rules as other outbuildings. The key requirement is that the use must be incidental to the enjoyment of the main dwelling.
Conditions
- 1Must be for purposes incidental to the enjoyment of the dwelling
- 2Must not be forward of the principal elevation
- 3Same height limits as outbuildings (2.5m within 2m of boundary; 4m/3m elsewhere)
- 4Must not cover more than half the curtilage
- 5Must not be used as sleeping accommodation or a separate dwelling
Size and Dimension Limits
- Height within 2m of boundary: 2.5m maximum
- Height elsewhere: 4m (dual pitch) or 3m (other roofs)
- Total outbuilding area must not exceed 50% of curtilage
When Permitted Development Does Not Apply
- Using a garden room as a bedroom, flat, or rental property requires planning permission (change of use)
- Designated area restrictions apply
- Full plumbing (kitchen, bathroom) may suggest non-incidental use
- Insulation, heating, and utilities do not by themselves change PD status
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 1m from any boundary or non-combustible construction. Over 30 square metres: Building Regulations apply. Electrical installations must comply with Part P regardless of size.
Building regulations are separate from planning permission. Even if your project is permitted development, you may still need building regulations approval. Contact Shropshire building control or use an approved inspector.
How to Apply in Shropshire
If you need planning permission for your garden room, you can apply through Shropshire'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 Shropshire. 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?
Moderate risk if used as a separate dwelling or sleeping accommodation. The council can take enforcement action against unauthorised residential use, regardless of whether the building itself was built under PD rights.
