Are you dreaming of a picturesque garden office or a charming summerhouse in your outside space? Before diving into a purchase, it’s essential to consider the intricacies of planning law. The burning question: Do you need planning permission for garden buildings?
In the UK, the rules governing garden buildings are dictated by local planning authorities. Each council may have different guidelines. Understanding the nuances of permitted development rights is key, as they allow you to make certain changes to your property without formal planning permission, provided your project fits within specific criteria.
Considerations
In England, for instance, you generally won’t need planning permission for a garden building if it adheres to the following conditions:
- The height of the building enclosure or container cannot exceed:
i) 4 metres in the case of a building with a dual-pitched roof,
ii) 2.5 metres in the case of a building, enclosure or container within 2 metres of the boundary of the curtilage of the dwellinghouse, or
iii) 3 metres in any other case (eg mono-pitched roof)
The height of the building, enclosure or container should be measured from the highest ground level immediately adjacent to the building, enclosure, or container to its highest point.
The height limit on a ‘dual-pitched roof’ of 4 metres should also be applied to buildings that have ‘hipped’ roofs (slopes on all four sides).
If any part of the building, container or enclosure is within 2 metres of the boundary of the curtilage of the house, then the height limit for the total development is restricted to 2.5 metres if it is to be permitted development. - Location Considerations: Ensure that the garden building is positioned behind the front wall of your house and not within conservation areas or national parks.
- Cumulative Area Limit: If your property already has other buildings, the total area of all structures (including the proposed garden building) should not surpass half the land’s total area.
These guidelines are a starting point, but it’s crucial to verify the specifics with your local council, as regulations may vary across the UK.

- The maximum size of the outbuilding (located more than 20 metres from your house) is 10 square metres
- If any part of your new building sits between the side of your house and the boundary of your property, you must seek planning permission
