Beyond Class Q: Exploring Permitted Development Opportunities for Rural Diversification
Class Q is often the first permitted development right that comes to mind when considering the future of agricultural buildings. But converting buildings to residential use is not the only option available to landowners.
There are other permitted development rights that may support the reuse of agricultural buildings and, in some circumstances, other forms of rural diversification. There are also opportunities that may require a full planning application.
From commercial and business uses to tourism, leisure and recreation, understanding what may be possible, and which planning route is most appropriate, can help landowners make better use of existing buildings and land.
Our Managing Director, Robert Dougherty, explains what opportunities are available beyond Class Q and what landowners should consider when looking to diversify their agricultural land and buildings.
What opportunities are available beyond Class Q?
Class Q is a permitted development right that allows certain agricultural buildings to be converted to residential use, subject to specific conditions and limitations. It’s just one of a number of permitted development rights that can apply to agricultural buildings.
One of the other key provisions for landowners is Class R, which allows certain agricultural buildings, together with land within their curtilage, to change to a range of commercial uses. Following changes introduced in 2024, Class R can cover uses including commercial, business and service uses, storage and distribution, hotels and outdoor sport or recreation, subject to the relevant limitations and conditions.
For landowners with agricultural buildings that are underused or no longer required for their original purpose, this may create opportunities to introduce a new use while making productive use of existing buildings.
However, Class R is not a blanket permission for diversification. The building, site and proposed use all need to meet the requirements of the permitted development right, and some proposals may also be subject to a prior approval process.
It is therefore important to establish what the relevant permitted development right actually allows before assuming that a proposed use can proceed without a full planning application.
What types of diversification could landowners consider?
The opportunities will depend on the individual farm, buildings, location and planning position. Potential options could include:
- Commercial and business uses
- Offices or workspace
- Farm shops and other rural commercial uses
- Storage and distribution
- Tourism and hospitality
- Leisure and recreation
- Outdoor sporting activities
- Other uses that complement the existing agricultural business
Some of these may benefit from permitted development rights, while others may require planning permission. The distinction is important, particularly where a proposal involves more than simply changing the use of an existing building.
A proposal for a new leisure, tourism or commercial use, for example, may also involve new buildings, extensions, access arrangements, parking, hardstanding, fencing, lighting or other infrastructure. These elements need to be considered alongside the proposed use.
The fact that a particular use is potentially covered by permitted development does not necessarily mean that the whole development can proceed without planning permission.
What does permitted development actually mean?
Permitted development rights are set out in national planning legislation and allow certain forms of development to take place without a full planning application, provided the relevant conditions and limitations are met.
This does not mean that all permitted development is automatic. Some rights are subject to a prior approval process, where the local planning authority considers specific aspects of the proposal before it can proceed.
For landowners, understanding the detail is therefore important. The question is not simply whether a use is permitted, but whether the specific development proposed on the specific site meets the requirements of the relevant permitted development right.
What are the common challenges?
The challenges will vary depending on the type, scale and location of the proposed development, but some of the issues that commonly need to be considered include:
- Access and highways can be particularly important where a new commercial, leisure or other use is likely to generate more traffic than the existing agricultural use. Visibility, access arrangements, vehicle movements and parking all need to be considered.
- Noise and lighting may also be significant, particularly where a new use could generate activity during the evening or introduce external lighting. The proximity of neighbouring properties and the potential impact on residential amenity should be considered from the outset.
- There can also be landscape, visual and ecological considerations. New buildings, infrastructure, lighting or activity can change the character of a rural site, while existing trees, hedgerows and habitats may need to be protected.
Other considerations may include drainage and flood risk, heritage, landscape designations and local planning policies, depending on the circumstances of the site. Early assessment can help identify these issues and, importantly, identify whether there are ways to address them before significant time or money is committed.
What should landowners consider before investing in a diversification project?
The starting point should be a review of the whole site and its existing planning position.
Before investing significantly in a proposed scheme, it is worth asking:
- What is the planning history of the site and existing buildings?
- Are there agricultural buildings that could be reused?
- What permitted development rights could apply?
- What are the limitations and conditions of those rights?
- Is the proposed use appropriate for the location?
- Does the proposal involve more than a change of use?
- Would new buildings, extensions, access, parking, lighting or other infrastructure be required?
- How would the development affect neighbours?
- Are there landscape, ecological, heritage, drainage or flood risk considerations?
- Are there any planning policies or designations that could affect the proposal?
- Would permitted development provide the best route, or would a planning application offer greater flexibility?
Answering these questions early can help landowners understand what is realistically achievable and identify the most appropriate planning route before significant investment is made.
What if Class R permitted development rights don't apply?
If Class R does not apply to a proposed diversification project, that does not necessarily mean the development cannot go ahead. It may simply mean that a different planning route is required.
Permitted development rights are limited, and some projects may be better suited to a full planning application, particularly where they involve new buildings, significant infrastructure or development that falls outside the scope of the relevant permitted development right.
A planning application can also provide greater flexibility where the proposed development cannot be accommodated within the restrictions of permitted development.
The important thing is to establish the most appropriate planning strategy for the site and proposed use, rather than trying to fit a project into a permitted development right that may not be suitable.
At RDC, our planning, architecture and landscape architecture teams work together to help landowners explore the potential of their land and buildings, from initial feasibility through to planning and delivery.
If you are considering diversifying your farm, we can help you understand what may be possible, identify potential constraints and establish the most appropriate route forward.
