Barn Conversions

Barn conversions can become amazing places to live, if the design is sympetaly completed in line with the character and the existing structure.

We will work with your own barn conversion ideas to create a stunning place to live.

Leeds and West Yorkshire has amounts some of Brittan’s most sought after countryside making it an ideal location to convert a barn to a dream home.

Planning laws have relaxed around converting barns and agricultural/farm buildings, which has seen a boost in popularity meaning it is becoming increasingly easy to create character rich warm homes in rural areas.

Barns vary in size but generally are long rectangular buildings, this gives architectural designers a blank canvas and great scope to create innovative barn conversion floor plans and modern living spaces.

As with all new build designs you need to consider the impact, amenity, utilities, access, services & ventilation. Then it will need to be passed through building regulations before any work can commence.

Size orientation and outlook will be the key factors in designing a barn into modern living spaces. As they are typically long buildings, through rooms are not always avoidable, but with high apex roofs, your architectural designer can create wonderful open mezzanines and galleries.

Insulation will typically be formed within the fabric of the building, leaving the existing structures external finishes as originally intended. All additional openings, windows, and roof lights will be in keeping, no one wants white PVC windows within a brick and timber structure.

Whether you have barn conversion ideas in mind or are thinking of a barn conversion extension to an existing dwelling your architectural designer will be able to produce all plans, building regulations, planning permissions, schedule of building works, full project management or builder referrals. We also offer  3D images / 3D visualisation for you, follow the link to examples of 3D visualisations.


Creating the right design, you will need to decide how many rooms you want, and which rooms need orientating to the best outlook. Generally, the space you have available is the size of the outer walls, with some deduction for the new insulated internals. Once the rooms are laid out, access, hallways, toilets, en-suites, open plan Kitchen/living areas then the all-important glazing can be worked out.

Split levels can be a great feature too, not only can they look fantastic but often help make up space in height what you may not have in floor area.

Barn conversion plans usually face stiff opposition from local authority and residents, due to farm building protection, open countryside development restrictions, infrastructure, sustainability, etc. However, the Barn Conversion clause comes about as part of a new Class – MB – into Part 3 of the Second Schedule of the General Permitted Development Order. This new class authorises the change of use of a building and any land within its curtilage from use as an agricultural building to a use falling within Class C3 – dwellings. It also authorises building operations ‘reasonably’ necessary to convert the building to residential use.

The site must have been used solely for agricultural use and have existed as a barn by 20th March 2013 (no building new barns!). New barns can be built and converted into homes but must exist as solely agricultural buildings for at least 10 years.

The total floor space of your barn to be converted must be no more than 450m². If the barn is bigger, you’ll only be able to convert to a maximum of 450m². The 450m² can however be divided into three separate dwellings. If the site is subject to an agricultural tenancy, landowners must have the express consent of their tenants.

Other facts to consider are Transport, noise impact, contamination, flood risk. and ‘Whether the location or siting of the building makes it otherwise impractical or undesirable for the building to change from agricultural use to residential use. Find out more about the Planning Process.

Don’t however let any other the above put you off converting a barn, with our expert knowledge we will discuss all options available before you commit to any plans.

Barn conversions are subject to the same rules as any new build. You will need to provide the following:


SAP calculations, this will design the energy efficiency of the home and give requirement for insulation and heating performance.


Disposal of waste and drainage, access.


The building will need to be assessed for structural stability.


Sound testing will be required on completion but all construction elements affecting sound need to be detailed and built in accordance with approved plans.


All other documents of the building regulations will need to be checked via full plans approval prior to commencing.
