What is Class Q permitted development?

Sutton Courtenay Barn Conversion

Today we’re looking to answer the question, “What is Class Q Permitted development?”.

As a refresher on permitted development, you can view our blog post on the differences between planning permission and permitted development.

Class Q is a specific form of planning permission which resides within the classification of permitted development.

Class Q permitted development essentially offers the owner of an agricultural building a streamlined path to change the use of that building into a residential dwelling as long as certain parameters are satisfied.

Potential Benefits of Class Q

Without a doubt, many owners of agricultural land and buildings could benefit from Class Q development. The regulations, introduced in 2015, allow change of use to be applied to former agricultural buildings, to create new residences.

It’s thought that Class Q was brought about partly to help alleviate the growing issue of low availability of suitable available residences in rural locations.

As a form of permitted development, another potential benefit to land owners is that the planning process could be significantly cheaper, streamlined and faster to obtain than traditional planning permission.

The reuse and repurposing of existing buildings has environmental and heritage benefits. By using old agricultural buildings as new residential dwellings we remove the need to build from scratch. This retains character in the building and preserves the look and feel of the local area for the benefit of all.

What is Permitted?

Firstly, your building must have been used for agricultural purposes prior to 20 March 2013.

It’s also important to note that Class Q cannot be applied to buildings situated in Areas of Outstanding Natural Beauty (AONB), conservation areas or national parks.

However, should your building satisfy the requirements you are potentially able to:

  • Create up to 3 larger dwellings (Upwards of 100m² but not exceeding 465m² in total)
  •  Create up to 5 smaller dwellings (Up to 100m² each)
  • It is possible to combine the 2 above points as long as you do not exceed 5 units in total (So you could have 4 x 100m² dwellings + 1 x 465m² dwelling)

What are the Restrictions?

A few of the restrictions surrounding Class Q permitted development have been mentioned above.

There are a few more considerations that landowners should be aware of:

  • It’s important to understand that any development must be within the footprint of the existing agricultural building
  • You cannot raise the existing roof height
  • Class Q does not allow building operations other than the installation or replacement of windows, doors, roofs, or exterior walls
  • Note that works related to water, drainage, electricity, gas or other services regarded as reasonably necessary for the building to function as a dwelling are permitted

The Legislation

You can find the government legislation here.

Get the Advice you Need

If you are still unsure whether your property qualifies for more Class Q permitted development. Or simply require more information on the subject. You can contact Simple Planning Solutions using the contact links in the footer of this post.

It’s always a common sense approach to get expert advice before embarking on a building project.

I honestly cannot praise Michelle enough. I have a listed building and was at my wits end trying to work out exactly what my local council required of me. In desperation I found Michelle on a Google search and she was absolutely marvellous. She took over everything, dealt with the replacement window company, the architect and the council and magically I had listed building consent within a very short space of time. I was told up front what the cost would be and there were no hidden extras. I will definitely be using Simple Planning Solutions again as I have more work which requires consent. Thank you Michelle you lifted a huge weight from my shoulders!

Simple Planning..Simply Stunning!!Excellent Service!! Michelle has been amazing. She is an experienced planning officer who is able to provide a wealth of knowledge and information. Thanks to her advice and her application support document, we have recently had our application approved which we are over the moon about. Michelle has helped at every stage and has worked with the surveyors, architect and most recently negotiated with the planning officer during the application to ensure approval. Her fees are very reasonable and she is so easy to talk to and deal with. Very few of us who are not in the industry have the knowledge to support these complex applications to give them the best chance of success and I think this possibly the best money I have ever spent for her help with this project. I can't recommend Simply Planning enough. Well deserved 5 stars!!

Michelle responded quickly to mine and my husband’s initial inquiry and offered a free high level assessment of the proposal. She came back the next day and we really appreciated her view and honesty over the unlikelihood of achieving what we wanted. She was clear and explained her thoughts. She could have dragged out the process or said she needed to perform a costly assessment but she didn’t. We hugely valued this. Would definitely recommend.
