Permitted Development Order or GPDO (as amended)

GPDO - Permitted Development

Permitted Development allows for exciting potential

The General Permitted Development Order or GPDO for short gives permission to carry out certain items such as extensions, rear dormers, erect fences, porches, external gyms, satellite dishes etc.

There are many items, both large and small, that can simply be built under permitted development subject to certain restrictions, building regs etc. in many cases, especially with houses, you can just go ahead. But do check for local restrictions, including covenants and conservation areas. Your permitted development rights may be restricted due to either an Article 4 or a previous planning application. So it is worth checking. 

If you need guidance as to how you can maximise the development on your property, consider booking a Zoom session with Ian Walmsley, the founder of Planning Geek. 


Index to all the articles / sections within the GPDO


You can now come direct to this section via the domain gpdo.co.uk

Other items within the permitted development (GPDO) require what is called ‘prior approval‘. This involves submitting a request to the local authority. They can only assess the application on items such as flood risk, noise, contamination depending upon the works to be carried out. This prior approval takes 28 or 56 days, depending upon the request. Note: permitted development rights do not apply to flats in many situations. 

The last major revision to the GPDO was in 2015. This forms a baseline to the current version. Please do not rely upon this original version as there have been many changes. This website will always aim to be up to date with all the changes. You can find a link to the latest official GPDO and changes on our links page. To date, no less than twelve revisions have taken place. 

On our website you can find articles relating to various elements of permitted development. The GPDO is divided up into ten Articles. You can find all these on the Articles page or via the menu above or to the side.

Some of the sections that we cover here include (check the articles list for more):

Part 1 – Development within a curtilage of a dwellinghouse

Part 2 – Minor operations

Part 3 – Changes of use

Part 4 – Temporary buildings and uses

Part 5 – Camping and Caravan sites

Part 6 – Agricultural and Forestry

Part 14 – Renewable Energy

Part 20 – Construction of new dwellinghouses (in airspace)
