There are some requirements that, if your orangery fits within these boundaries, may exempt the extension from requiring planning permission. These include:
- The extension is single-storey
- The property has not already been extended
- The materials used in the construction of your home are similar to those used in the construction of the extension
- The extension does not extend over more than half of the property’s garden
- The roof ridge or peak does not exceed the height of your property’s eaves
- The height of the extension does not exceed 4 metres, or 3 metres if the extension is within 2 metres of your property boundary
- The extension does not reach beyond half the width of the property.
- The extension has no verandas, balconies or raised platforms
There may be further limitations depending on your developers. These can include:
Approval may be required to build a new structural opening between the property and the extension.
If you build an orangery without obtaining the relevant permissions it may not necessarily cause problems provided you meet the above guidelines. However, if your neighbours take it upon themselves to report it to the council and your orangery does not comply with these regulations, you could face investigations and/or a fine of up to £5000. Online planning permission requests usually cost around £150.
Confusingly, planning permission and building regulations refer to separate ideas and are not interchangeable terms. Local councils control both of these regulations, but the key difference between the two is that building regulations determine the functional characteristics of the property, but planning permission refers to how the aesthetic of a new building or extension relates to the its neighbouring properties.
