Garden rooms have become increasingly popular, offering a versatile and stylish way to add extra space to a property. Whether used as a home office, gym, art studio, or guest accommodation, a well-designed garden room can enhance both functionality and aesthetics.
However, before construction begins, it is essential to understand whether planning permission is required. The need for planning permission depends on several factors, including size, location, and intended use. This guide outlines the key planning rules, considerations, and how we can assist with the entire process if permission is required.
Do Garden Rooms Need Planning Permission?
Many garden rooms fall under Permitted Development Rights (PD), meaning planning permission is not required. However, there are specific criteria that must be met to comply with these rules. While the criteria varies slightly between England and Wales, A garden room can generally be built without planning permission if it meets the following conditions:
It is a single-storey structure
The maximum eaves height is 2.5 metres, with an overall height of 4 metres for a dual-pitched roof or 3 metres for other roof types
If located within 2 metres of a boundary, the maximum height must not exceed 2.5 metres
It does not take up more than 50% of the total garden area
It is not intended as a permanent living space (i.e., not a self-contained dwelling)
It is not built in front of the principal elevation of the house
The property is not listed and is not located in a designated area such as a National Park, Area of Outstanding Natural Beauty, or Conservation Area
If a garden room complies with all these conditions, it can usually be built under Permitted Development Rights, meaning no formal planning application is necessary. If any of these conditions are not met, planning permission will be required.
When is Planning Permission Required?
Planning permission must be sought if the proposed garden room:
Is taller than 2.5 metres and located within 2 metres of a boundary
Covers more than 50% of the total outdoor space
Is intended to be used as a self-contained living space, such as an annexe or short-term rental
Is located in a listed property or a conservation area
Is built in front of the main elevation of the house
