Permitted Development Rules for an Orangery
Generally permitted under Part 1, Class A, following the same rules as single-storey extensions. An orangery is treated identically to any other single-storey rear extension for PD purposes.
Conditions
- 1Same conditions as single-storey rear extensions
- 2Maximum depth 3m (semi/terraced) or 4m (detached) under standard PD
- 3Maximum height 4m; eaves 3m if within 2m of boundary
- 4Materials should be similar in appearance to the existing dwelling
- 5Must not cover more than half the curtilage
Size and Dimension Limits
- Maximum height: 4m
- Eaves height: 3m if within 2m of a boundary
- Depth: 3m (semi/terraced) or 4m (detached) under standard PD
When Permitted Development Does Not Apply
- Same limitations as single-storey extensions
- Cumulative total of all extensions and outbuildings must not cover more than half the curtilage
- Unlike conservatories, orangeries are unlikely to qualify for the Building Regulations exemption (due to solid walls)
What About Building Regulations?
Building regulations approval is likely required
Building Regulations approval is usually required as orangeries have substantial masonry walls and are generally integrated into the house. Covers structural stability, foundations, thermal performance (Part L), ventilation, drainage, and electrical installations.
Building regulations are separate from planning permission. Even if your project is permitted development, you may still need building regulations approval. Contact Birmingham building control or use an approved inspector.
How to Apply in Birmingham
If you need planning permission for your orangery, you can apply through Birmingham'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 Birmingham. 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?
Same enforcement risk as single-storey extensions. Orangeries that exceed PD limits without permission can be subject to enforcement notices requiring alteration or removal.
