Box Construction Barn Renovation
What is a Box Construction Barn?
Box construction barns, also known as box frame or plank frame barns, are a traditional style of barn built using a framework of vertical posts and horizontal beams, without relying on interior curved timbers. Instead of the entire structure depending on large framing components, the load is distributed more evenly across vertical planks and timber posts. This method became more popular in the 19th and early 20th centuries, offering a straightforward and cost-effective approach to barn building.
The architectural relevance of box construction barns lies in their simplicity and adaptability. While they may not be as old as cruck frame barns, their clean structural lines and ease of assembly made them a practical solution for rapidly expanding agricultural needs. Many still stand today, offering a glimpse into more recent rural construction methods.
COST OF RENOVATING A BOX CONSTRUCTION BARN
A barn renovation can be one of the most challenging construction projects to undertake, so it’s no wonder that renovating a barn can cost anywhere from £150,000-£500,000. However, the actual cost you will pay is dependent on several factors, such as the size of the barn and the complexity of the project. As a rough guide, you can expect to pay around £1,700 per m2.
Factors Affecting the Cost
- Structural Work: If you need to reinforce or replace beams and walls, this will drive up the cost, as will the extent of structural work required.
- Material Choices: Barn conversions often use authentic or reclaimed materials to preserve the barn’s character and rustic appearance, and these materials can cost more compared to modern alternatives.
- Interior Design: Flooring, insulation, lighting and décor all contribute to the overall cost.
- Special Features: The restoration of unique architectural elements, such as wooden joists and vaulted ceilings, is delicate and costly work.
- Permits and Professional Fees: Barns are usually protected historical buildings, so it costs money to work on them and apply for the relevant permits. You will also need to work with professionals, such as architects and surveyors, who will come with their own fees.
When looking at the costs associated with renovating a barn, it’s worth remembering the resale value. Many people have bought old and derelict barns, turned them into stunning homes and still sold them for a massive profit. Barn conversion homes can sell for well over £500,000 with some selling for over £1-£2 million.

MATERIALS USED TO RENOVATE BOX CONSTRUCTION BARNS
- Timber: Oak, pine, or other historically appropriate woods are used to restore or replace a barn’s structural framework.
- Roofing Materials: Depending on the barn’s original style, slate, clay tiles, or corrugated sheets may be used for the roof. For a barn renovation, it’s best to opt for modern options that provide good insulation while also retaining historical charm.
- Insulation and Walls: Natural materials like sheep wool, hemp, or cork will improve energy efficiency. You could also go for traditional lime plaster or render for more breathable walls.
- Flooring: Depending on the purpose of your renovated barn, you could choose reclaimed wood, stone, or polished concrete.
- Doors and Windows: To match the barn’s original design, you could restore existing doors and windows or go for custom-built options. Choose energy-efficient glazing for modern functionality.
Common Uses of Box Construction Barns
Historically, box construction barns have been used for:
- General storage
- Animal stabling
- Equipment and tool housing
- Grain and feed storage
In modern times, these barns are commonly:
- Renovated into guesthouses or homes
- Converted into event venues or studios
- Repurposed for agricultural tourism or retail spaces

Box Construction Barn Renovation Process
Step One: Initial Assessment
The first step in renovating a box construction barn is to undertake an initial assessment. The main task will be to evaluate the barn’s structural integrity, identifying any signs of wear, decay or damage. As most barns are old buildings, a survey will likely be needed to identify any historical or architectural features that will need to be preserved.
Step Two: Planning and Design
The next step is to put together a renovation plan, detailing how you will integrate modern needs and features while also maintaining the barn’s history, character and charm. During this design phase, you will coordinate with architects, engineers, and possibly conservation officers (if the structure is protected) to come up with a design that prioritises functionality and style, while also complying with planning/building regulations.
Step Three: Structural Repairs
Box construction barns that are to be renovated into residential or commercial spaces will need to undergo some structural work. This stage of the project usually involves restoring or replacing timber framework and reinforcing walls and foundations. This is especially important for barns showing age-related weaknesses.
Step Four: Modernisation and Functionality
To convert a box construction barn into a habitable living space, you will need to add the necessary facilities, like plumbing, electrical system, and heating, while also respecting the original structure. Remember, the facilities you add will be dependent on what you are repurposing the barn for – a new home, event space, storage location, etc.
Step Five: Finishing Touches
With the bulk of the work completed, now is the chance to go over the newly renovated barn and apply any finishing touches, such as restoring or replicating features like wooden beams or barn doors.
WHY RENOVATE A BARN INSTEAD OF DEMOLISHING IT?
Barns are incredible examples of historical British architecture, and just because one may no longer be used for agricultural purposes, that doesn’t mean you have to demolish it. Keeping a historical building standing and breathing fresh life into it can be incredibly rewarding. Plus, barn conversion homes are incredibly beautiful and located in desirable countryside locations.
WHAT TYPE OF SPACES CAN A BARN BE CONVERTED INTO?
Barns are commonly converted into residential properties, but they can also be turned into commercial spaces, such as countryside offices, hotels and B&Bs, or even be converted into event spaces that can be hired out for such functions as weddings or charity balls.
DO I NEED PLANNING PERMISSION FOR A BARN RENOVATION?
No, a barn conversion without planning permission is possible. Barn conversions can fall under permitted development rights. This means that if your project meets certain criteria, you can convert a barn into a house or something else without the need for planning permission.
HOW DO I ASSESS IF THE BARN STRUCTURE IS SOUND?
To check the structural integrity of a barn, you will need the help of a structural engineer or surveyor. They can conduct an inspection to determine the condition of the barn’s structure.
WHAT ARE COMMON CHALLENGES IN BARN CONVERSION PROJECTS?
Barn conversion projects are one of the most difficult construction projects around, so they can come with their fair share of challenges, such as tricky planning/building restrictions, being difficult to access, and sourcing appropriate materials.
HOW MUCH DOES A TYPICAL BARN RENOVATION COST?
To convert a barn into a residential or commercial premises, you can expect to pay around £1,700 per m2. Overall, the project could cost anywhere between £150,000-£500,000.
ARE THERE SPECIFIC BUILDING REGULATIONS FOR BARN CONVERSIONS?
Yes, barn conversions must comply with several building regulations, including regulations relating to structural integrity, insulation & energy efficiency, fire safety, drainage & waste disposal, windows & glazing, accessibility, and electrical & plumbing.
