One of the most important decisions farmers and landowners need to make regarding agricultural sheds is choosing between timber and steel. Both materials offer distinct advantages and limitations depending on your farming operation, budget, aesthetic preference, and long-term plans.
At Blackdown Buildings, we specialise in designing and constructing high-quality farm buildings across the South West, including Devon, Somerset, Dorset, and Cornwall. In this blog, we’ll explore the key differences between timber and steel agricultural sheds to help you make an informed choice for your next project.
What Are Agricultural Sheds Used For?
Agricultural sheds serve a wide variety of purposes on farms and rural properties. They can be used for:
- Storing machinery, feed, and equipment
- Housing livestock
- Creating workshops or packing facilities
- Dry storage for harvested crops and hay
- Protecting vehicles from the elements
Given their importance to daily operations, your shed must be built to last, comply with local planning regulations, and suit the specific needs of your agricultural business.
We offer a range of purpose-built shed designs to suit your operational needs. If you’re looking for a traditional option with generous internal space, our Portal Frame Sheds are ideal for everything from machinery storage to livestock housing. For sites with height or access restrictions, or if you prefer a more compact and cost-effective solution, our Mono Pitch Sheds offer excellent versatility. Both timber and steel construction options are available across these designs, providing flexibility for every farm setting.
Timber Agricultural Sheds
Benefits of Timber
Timber agricultural sheds have been a traditional choice in British farming for centuries, and for good reason.
- Aesthetic appeal: Timber blends seamlessly with the rural landscape, offering a natural look that’s often preferred in Areas of Outstanding Natural Beauty or Conservation Areas.
- Sustainability: Timber is a renewable resource and can be sourced responsibly.
- Natural insulation: Wood has better thermal properties than steel, which can help regulate temperature within the building, particularly important for livestock or sensitive crops.
- Planning permission: In some areas, planning authorities prefer timber-clad buildings for aesthetic and environmental reasons.
Our timber agricultural sheds combine traditional craftsmanship with modern techniques to ensure strength and longevity. Whether you’re building a hay store or a lambing shed, our timber designs can be fully customised to suit your farm’s layout and style. Take a look at our Farm Buildings page to see examples of completed timber-framed projects across Devon, Somerset, Dorset, and Cornwall.
Considerations
However, timber does require maintenance. Without proper treatment and care, it can be susceptible to rot, pests, or warping over time, particularly in damp or coastal areas such as North Devon or West Somerset.
Steel Agricultural Sheds
Benefits of Steel
Steel agricultural sheds are increasingly popular due to their durability and low maintenance requirements.
- Strength and durability: Steel is highly resistant to extreme weather conditions, fire, and pests, making it a robust option for exposed locations like the Cornish coast or the Quantock Hills.
- Lower maintenance: Galvanised or coated steel frames require minimal upkeep compared to timber.
- Large clear spans: Steel frames can create wide internal spaces without the need for internal supports – ideal for machinery storage or grain stores.
- Fast construction: Steel-framed buildings can be erected quickly, reducing downtime for busy farms.
Steel agricultural sheds are particularly well suited to large-scale operations that require expansive, clear internal space. We supply and construct robust steel-framed buildings for grain stores, equipment workshops, and multi-use agricultural storage. With flexible options including our Portal Frame Sheds, steel offers a long-term investment with low maintenance and high performance, perfect for modern farming demands.
Considerations
On the flip side, steel can be more prone to condensation without appropriate insulation or ventilation. Additionally, some planning authorities in rural areas may be less inclined to approve large, industrial-looking structures, especially in National Parks or heritage sites.
Environmental Considerations
Sustainability is increasingly important in the agricultural sector. When comparing timber vs steel, the carbon footprint of each material can make a significant difference over the lifespan of a building.
Timber is biodegradable, sequesters carbon, and can be locally sourced. It is by far the most carbon-efficient construction material, producing just 0.017 tonnes of CO₂ per tonne of material.
By contrast:
- Steel produces approximately 1.8 tonnes of CO₂ per tonne of material,
- And concrete generates around 0.6 tonnes of CO₂ per tonne.
These figures highlight how timber agricultural sheds offer a substantially lower environmental impact compared to other building materials. Choosing timber not only supports sustainable forestry practices but also helps reduce your farm’s overall carbon footprint.
That said, the longevity and recyclability of steel buildings also play a role in offsetting their environmental impact over time. Working with an experienced team like Blackdown Buildings ensures that sustainable design and material sourcing are carefully considered at every stage of your project, regardless of whether you opt for timber or steel.
Costs: Timber vs Steel Agricultural Sheds
Budget is always a key factor. While timber may have a lower upfront material cost, labour and long-term maintenance must be considered. Steel buildings often have a higher initial cost but may prove more economical over time due to their durability and reduced upkeep.
The exact cost will depend on:
- Size and scale of the building
- Access to the site
- Groundworks required
- Finishes and cladding choices
- Local planning regulations

Location-Specific Considerations Across the South West
We construct farm buildings throughout the South West, including:
- Devon: Whether you’re farming near Tiverton, Crediton, or Barnstaple, we can help you choose a shed that suits the terrain and climate of your land.
- Somerset: From the Mendip Hills to the Levels, we’ve built both steel and timber agricultural sheds to suit diverse farming needs.
- Dorset: With its mixed agriculture and coastal climate, farmers here benefit from robust structures that perform well in high humidity.
- Cornwall: We understand the unique challenges of farming in coastal and rural parts of Cornwall, including salt-laden air and high winds.
Choosing the Right Agricultural Shed for Your Farm
There’s no one-size-fits-all answer, your decision should be based on a combination of practical, environmental, and aesthetic factors. Here’s a quick summary:
| Feature | Timber Sheds | Steel Sheds |
| Aesthetic appeal | Natural, traditional | Industrial, modern |
| Durability | Requires maintenance | Very durable |
| Construction speed | Moderate | Fast |
| Cost (initial vs long term) | Lower initial cost, more maintenance | Higher initial, low maintenance |
| Environmental impact | Renewable, local | Recyclable, higher production impact |
| Planning considerations | Often preferred in rural areas | May require screening or cladding |
Choosing the right structure isn’t just about materials; the building style itself also plays a crucial role. For example, mono pitch sheds are popular for smaller storage areas or where planning regulations may restrict height. In contrast, portal frame buildings can span large areas with ease, making them ideal for machinery storage and livestock handling. Both styles can be built in either timber or steel, giving you full control over the function and appearance of your farm building.
