We are often asked if planning permission is required for greenhouses.
Greenhouses are covered by the same planning rules as outbuildings or other garden buildings.
Under planning rules greenhouses and sheds are considered to be permitted development, not needing planning permission, subject to the following limits and conditions:
- The greenhouse or shed should not be built forward of the front elevation of the house.
- The greenhouse should be single storey!
- The maximum eaves height is set at 2.5m with a maximum overall height of 4m (with a dual pitched roof) or 3m for a lean-to.
- The greenhouse should have a maximum height of 2.5m if it’s within 2m of a boundary of the curtilage (defined as the area accompanying the property) of the house. This still allows for most Elite greenhouses to be built right up to the boundary.
- The greenhouse should not cover more than half the area of land around the “original house” – this is the house as it stood in July 1948 (or when it was built if that is the latter date). It is worth bearing in mind in this case that although you may not have extended the property, a previous owner may have, but in most cases this would allow for a huge shed or greenhouse to be erected.
- In National Parks, the Norfolk Broads, Areas of Outstanding Natural Beauty and World Heritage Sites the maximum area to be covered by a greenhouse (more than 20m from house) is limited to 10m2.
- If your greenhouse is going on the side of the house within the above areas (AONB, National Park etc) Planning permission will be required.
- Within the curtilage of listed buildings any outbuilding will require planning permission.
If your greenhouse or shed plans do not fit with the above, or if you have any concerns then we would recommend contacting the planning office at your local council.
If you are worried about building regulations, for your new shed or greenhouse, have no fear. Building regulations are only applicable for habitable buildings, or structures such as Summerhouses over 30m2.
