Planning Permission for Timber Garden Buildings

Last updated: April 2019

One of the most frequent questions we are asked is 'Do I need planning permission for my Garden Building?'

All timber garden structures, including Garden Sheds, Summerhouses and Garages are subject to planning permission rules; however, the good news is that the majority of our buildings won't actually require planning permission for installation.

Whether you need planning permission or not will all depend on where you wish to place the building in your garden and if you should live in an area that has been designated as a national park or similar. Providing certain criteria are met and the building is considered permitted development, you can proceed without needing permission.


[edit] What Is The Maximum Height Garden Building I Can Have Without Planning Permission?

Garden Buildings are considered Permitted Development and do NOT require planning permission as long as:

[edit] Other Criteria to Consider Regarding Planning Permission for your Garden Building

    • (The term original house means the house as it was first built or as it stood as of 1 July 1948 (if it was built before this date). Any extension, even if completed by a previous occupier, does not constitute as the original house (unless it was in place on 1 July 1948).

If your garden building does NOT meet the above criteria, e.g. if you want a garden building taller than 2.5m and situated less than 2.0m from a boundary of your property, then you would NEED to apply for planning permission.

If, however, your garden building DOES comply with the above criteria, you won't need to apply for planning permission and you can have a garden building up to 30m2 (internal size). Anything bigger than 30m2 will need to go through building regulations.

[edit] Listed Buildings

Listed buildings are objects or structures that have been judged by Historic England and the Secretary of State for Culture, Media and Sport to be of national importance in terms of architectural or historic interest. These structures, once approved, feature on a dedicated register called the List of Buildings of Special Architectural or Historic Interest.

There are increased rules around listed buildings, so any garden building or outbuilding that is to be placed within the curtilage of a listed property will require planning permission. If you go one step further and require a structure to be built and attached to a listed property, you will need both listed building consent AND planning permission (although this is a service that Crane does not offer).

These restrictions should not put you off though, as we build a considerable number of garden buildings for customers with listed properties.

[edit] Designated Land

There are also additional limitations if your property is located on designated land. Designated land is the term used to describe areas of interest such as: national parks, the Broads, World Heritage Sites, Areas of Outstanding Natural Beauty and conservation areas.

There are two main points to get your head around with designated land: one includes conservation areas, one does not:

Once you have clarified these points and know that you are following the above criteria, you can refer to what we call, the 'normal planning rules'. These are the criteria that have been specified from the beginning of this article in the first two sections.
