Steel vs Timber Buildings: Which Is Better for Farms & Commercial Use in the South West?

If you’re planning a new agricultural or commercial building in Somerset, Devon, Dorset or across the South West, one of the first decisions you’ll face is:

Steel or Timber?

Both have their place — but for most farms and commercial sites in the South West, steel buildings are the stronger long-term choice. This guide explains why, in plain English, so you can make the right call for your site and budget.

Initial Cost: Steel vs Timber Buildings

Timber buildings often appear cheaper at first glance — and sometimes they are.

However, once you compare:

• Structural lifespan

• Maintenance costs

• Insurance implications

• Long-term usability

…the gap usually closes quickly.

In real-world South West projects, steel and timber buildings often end up within the same price range, especially once installation, foundations, and compliance are factored in.

Lifespan & Durability (This Is Where Steel Wins)

South West weather is not kind to buildings:

• Damp air

• Driving rain

• Coastal salt exposure

• Muddy agricultural environments

Steel buildings typically last 30–50+ years with minimal maintenance.

Timber buildings:

• Are vulnerable to rot

• Can suffer from insect damage

• Often require ongoing treatment or replacement of structural elements

• 
  

For farmers and commercial operators, steel is usually a build-once, forget-about-it solution.

Maintenance & Ongoing Costs

Maintenance is rarely discussed when prices are compared — but it matters.

Steel Buildings:

• No rot

• No insect issues

• Minimal structural maintenance

• Predictable long-term costs

Timber Buildings:

• Regular inspections required

• Risk of decay in wet conditions

• Ongoing treatment costs

• Higher chance of unexpected repairs

Over 10–20 years, steel buildings are usually cheaper to own, even if the initial cost is similar.

Fire Risk, Insurance & Peace of Mind

This is a big one for farms and commercial sites.

Steel buildings:

• Are non-combustible

• Often attract lower insurance premiums

• Reduce risk when storing machinery, hay, feed or fuel

Timber buildings:

• Are combustible

• May increase insurance costs

• Can limit use depending on contents

For many South West farmers, insurance and fire risk alone are enough to justify choosing steel.

Speed of Construction

Time matters — especially during busy seasons.

Steel buildings:

• Are fabricated off-site

• Install quickly once foundations are ready

• Less weather-dependent during erection

Timber buildings:

• Often require more on-site labour

• Can be delayed by weather

• Take longer to complete

Faster builds mean less disruption to day-to-day operations.

Flexibility & Future-Proofing

Steel buildings are easier to adapt in the future:

• Extensions

• Door changes

• Internal reconfiguration

• Conversion to commercial or industrial use

If there’s any chance your building use may change later, steel gives you far more flexibility.

When Timber Might Make Sense

To be fair, timber does still suit some projects:

• Small, low-cost storage buildings

• Temporary structures

• Very low exposure environments

• Projects where appearance outweighs longevity

But for most working farms and commercial sites, timber is often a compromise.

Why Steel Is the Preferred Choice Across the South West

Across Somerset, Devon, Dorset and surrounding counties, we see the same trend:

Farmers and commercial clients increasingly choose steel because it offers:

• Longevity

• Reliability

• Lower lifetime cost

• Better insurance and fire performance

• Strong resale value

Steel buildings simply suit the realities of South West conditions better.
