Does your barn conversion need planning permission?
Redundant or underused agricultural buildings can represent a significant opportunity for landowners. Under Class Q permitted development rights, certain agricultural buildings can be converted into residential homes without going through the traditional full planning application process.
At Andrew Granger & Co, our planning specialists can help you understand whether your building could qualify, assess the potential of the site and guide you through the application process.

Class Q is a form of permitted development that can allow qualifying agricultural buildings to be converted into residential dwellings without requiring a conventional full planning application.
It can provide an opportunity to give an existing building a new purpose while potentially creating valuable residential accommodation.
However, not every agricultural building will qualify. There are specific rules covering the building, its previous use, location, floorspace, design and the works proposed.
That's why establishing eligibility at an early stage is so important.
Under current legislation, Class Q can be used to create up to 10 new homes, with a combined floorspace of up to 1,000 sqm on one holding.
The maximum size of any dwelling created is 150 sqm.
An applicant will be able to extend to the back of the barn or agricultural building by up to 4m on any hard surface which was present on or before the 24th of July 2023.
Class Q applications have a deadline of 56 days for a decision. If the local authority has not made a decision in that time, the application can receive deemed consent.

Every agricultural building presents different opportunities and constraints. Looking at previous projects can help demonstrate how existing structures can be transformed into attractive, functional homes.

Once a Class Q application has been approved, it's possible to apply to replace the consented unit(s) with a new residential dwelling(s).
This can enable you to create a new residential dwelling(s) in a location where it would not be possible under the traditional planning process.
The key is the proposed scheme must be ‘better’ than the Class Q scheme it's replacing. This can be achieved in a number of ways including better design and/or incorporating renewable energy resources.
Our award-winning planning and architecture team are here to guide you through the process from start to finish.
