From agricultural to residential: a guide to Class Q planning

Words from Mariyana Hartland – Chartered Architectural Technologist within our in-house Architectural Design team

 

Having an agricultural barn in the open countryside doesn’t necessarily mean the end of a journey for creating a more exciting and inspirational building. Introduced in 2014, Class Q is a form of permitted development which supports housing supply in rural areas (such as open countryside and green belt land) and those areas without defined settlement boundaries.

 

An example Class Q case study:

The image below is of an application we submitted for planning permission after our client secured prior approval. This is for a new dwelling in open countryside. The existing building is a tired steel framed structure. As you can see from the images, we have proposed a replacement oak framed dwelling that is complimented with a combination of materials such as local Cotswold stone and slate, creating a lovely lifetime home for our clients.

What does the legislation for Class Q permitted development apply to?

Class Q permitted development applies to buildings that were used for agriculture on or before 20th March 2013, more specifically:

“(a) a change of use of a building and any land within its curtilage from a use as an agricultural* building to a use falling within Class C3 (dwelling houses) of the Schedule to the Use Classes Order;

And,

(b) building operations reasonably necessary to convert the building referred to in paragraph (a) to a use falling within Class C3 (dwelling houses) of that Schedule.”

*Agricultural use is defined as a business when also demonstrating a profit, so recreational use or growing produce as a hobby would not benefit from Class Q.

Under the latest amendments, Class Q includes two types of dwellings:

  • Smaller dwelling houses – 5 units; no more than 100 m2 each
  • Larger dwelling houses – 3 units; 465 m2 each

Using both categories could result in 5 dwellings and up to 865 m2.

 

What does the legislation for Class Q permitted development not apply to?

  • Conservation Areas, Areas of Outstanding Natural Beauty (AONB), The Broads and National Parks
  • World Heritage Sites
  • Designated scheduled monuments or listed buildings
  • Extending or enlarging the existing building beyond its existing external dimensions
  • Conversion of a building that is not part of an agricultural business on or prior to March 2013 or for a period of 10 years form that date.
