Converting a Barn - Planning Requirements

A Guide to Barn Conversion Planning Permission

Barn conversions have become increasingly popular in recent years as a unique and stylish way of repurposing an old building. The results can be staggering. Modern, unique homes with comfortable living spaces. The process of converting a barn into a habitable dwelling can be complex, particularly when navigating the planning process. It is important to work with a planning consultancy that specialises in barn conversion planning.

Barn conversions involve obtaining the right planning permission and building regulations approvals to ensure that the project complies with relevant legislation.

This can be a time-consuming and challenging process. It depends on the type, use size and location of the barn conversion, but may need to apply for full planning permission. You may be eligible for a simpler process called ‘prior approval’.

One of the key factors to consider when planning a barn conversion is the structural integrity of the building. Many barns are centuries old and may have suffered from neglect or damage over the years. It’s important to ensure that the building is safe and suitable for conversion before any work begins. This may involve carrying out surveys and assessments to identify potential issues, then determining the best approach to address them.

Another important consideration when planning to convert a barn is the design and layout of the building. Barns typically have large, open spaces that can be transformed into stunning living areas. It is important to ensure that the design is in keeping with the character and history of the building. This may involve working with an architect or designer on a plan to maximises space, while preserving any unique features. These conversions present opportunities and challenges in terms of creating a comfortable and functional living environment. You need to think creatively about how to divide the space, and how to incorporate features such as natural light and heating.

What are the factors that affect barn conversion planning?

  • Location
  • Historical significance
  • Surrounding buildings

These may all have an impact on the planning process. Working with a planning consultancy that has experience in barn conversion planning ensures that your application is prepared and presented in the most effective way possible.

It’s also important to consider the environmental impact of a barn conversion. This may involve carrying out environmental assessments to determine the potential impact on local wildlife, habitats, and ecosystems. It may also involve incorporating sustainable design features into the conversion, such as renewable energy sources or water-saving measures.

Navigating the planning system can become even more complicated when the existing barn is not a traditional stone or brick building. The buildings themselves may be historic, listed or simply not suitable for change of use to business or residential. It is imperative to review the specific planning policy of the relevant Local Planning Authority (LPA) carefully. It’s also important to understand which buildings are allowed, and what supporting information needs to accompany a planning application. Conservation Officers may be involved to review the application, to ensure that the character of the building remains intact.

Overall, barn conversion planning is a complex and challenging process that requires careful consideration of a wide range of factors. Working with an expert that specialises in barn conversion planning helps ensure that your project is a success. From obtaining planning permissions and building regulation approvals to designing a stunning and sustainable living space.

In conclusion, planning a barn conversion can be a highly challenging but rewarding process. By working with specialist advisors, and carefully considering the various factors involved, you can create a unique and sustainable living space that reflects your individual style and values. Whether you’re looking to create a family home, a holiday let, or a workspace, a barn conversion offers endless possibilities for those with the vision and commitment to make it happen.

Are there any other options to getting barn conversion planning for alternative uses?

Because of their nature (i.e. barns) they are often located where new buildings, homes or businesses, are not allowed, for example, Green Belt or open countryside. It can therefore be a challenge to obtain planning permission. There are other options for converting existing buildings, including  Class Q (barns and agricultural buildings to residential) and Class R (agricultural buildings to a flexible commercial use).

What is Class Q Permitted Development?

Can I Convert My Barn into a Home?

Yes – Most barn conversions come under permitted development legislation, (specifically Class Q of The Town and Country Planning – General Permitted Development – England – Order 2015) in England. A full planning application is not normally required, removing one of the biggest obstacles normally encountered in building development.

Class Q is designed to speed up the planning process, so that more buildings, particularly older ones sitting idle, can be brought into domestic use.

Permitted Development – Agricultural Buildings

The legislation allows for physical changes to buildings but not extensions. This includes installation (or replacement) of windows, doors, roof or exterior walls and services. There are further limitations such as the size of the space to be converted, the level of building works required, the location, and the lawful use of the building.

You will therefore need a Prior Approval Application to ensure that the PLA accepts your proposal. This is where all conversions including windows, doors & services can be approved. This process should normally take no longer than 2 months.

The process of prior approval is different to that of seeking planning permission. There are limited opportunities for the Local Planning Authority to prevent the change of use of the building from agricultural to a dwelling house.
