Agricultural farm sheds & facilities

This is a very open question as we are a design and construct company, so no two sheds are the same; however, AUSPAN farm sheds typically fall within the following ranges (all indicative and subject to design, location and specification):

• Machinery & Hay Sheds: Range from $100,000 +GST to $250,000 +GST
• Workshops: Range from $150,000 +GST to $600,000 +GST
• Storage sheds Grain/Fertiliser Sheds: Range from $150,000 +GST to $400,000 +GST

Example: A 24m × 40m enclosed Workshop shed with a 150mm slab, Sliding doors, P/A Doors and Skylights for a grower in Wagin cost approximately $400,000 +GST.

Yes. Most WA local governments require a Building Permit, and many also require Planning Approval depending on zoning, size and use. AUSPAN provides certified structural engineering, site plans, elevations and stormwater details to support your applications and help streamline approvals.

Example: In Dowerin, the shire required bushfire zoning checks; AUSPAN’s documentation helped avoid weeks of delay by clearly addressing the planning conditions.

Choosing the right size depends on your current machinery fleet, workflow and future plans.

Typical AUSPAN benchmark sizes include:

• 15–30m span for machinery sheds
• 5–7m wall height (6.5m is very common for modern equipment)
• Length is determined by our standard 8m bays so anything from 24m and up depending on the number and size of machines.

Example: A Moora grower expanded to a 24m × 64m shed after expanding their operation, needing more undercover space to store the extra machinery.

AUSPAN’s hot-dip galvanised portal frame sheds are designed for longevity, with structural steel for a minimum of 50 years with appropriate maintenance. Roof and wall sheeting (Colorbond® or Zincalume®) typically lasts 40 years depending on location and environment (for example coastal vs inland).

Concrete slab: Recommended for workshops, machinery storage and grain sheds where a hard, cleanable surface is required.

Compacted Gravel: Common for open hay sheds or machinery sheds where the shed is purely for storage and not a working area, and cost is a priority.

Concrete apron: Often added outside the main doors to provide a cleaner, safer transition area for machinery.

125mm-150mm reinforced concrete is common for machinery storage and general workshop use.

150mm reinforced concrete is recommended for very heavy axle loads such as large headers and air seeders, particularly where loaders will push into grain or fertiliser.

Most AUSPAN farm sheds in WA use roof pitches between 7.5° and 3°.

• 7.5° is standard for anything up to 21m span, 5° for anything between 22m and 26m span and 3° is standard for anything larger than 26m span. This applies to all AUSPAN sheds, but we can provide custom roof pitches upon request.
• Higher pitches (up to 20°) are sometimes chosen where additional airflow or heat reduction is desired, such as in shearing sheds or feedlot covers.

AUSPAN typically uses:

• Zincalume® for cost-effective performance where colour is less critical and heat is reflected.
• Colorbond® steel for premium appearance and long-term corrosion resistance.
• Colorbond® Ultra for appearance and highly corrosive environments, i.e., coastal.

Hot-dip galvanised structural steel frames are used to maximise durability and minimise corrosion risk, particularly important in fertiliser and coastal environments.

Routine maintenance helps maximise the life of your AUSPAN shed:

• Inspect gutters and downpipes annually and clear debris.
• Check fasteners, bracing and door tracks for wear or loosening.
• Touch up scratched or damaged painted surfaces.
• Wash down cladding more regularly in coastal, fertiliser or corrosive environments.

AUSPAN designs sheds to comply with AS/NZS 1170 wind regions and local terrain categories.

In Western Australia, this typically includes:

• Region A: Inland areas (many Wheatbelt locations).
• Region B/C/D: Northern Coastal and peri-coastal regions.

Example: AUSPAN’s sheds in Onslow (Region C) incorporate upgraded fixings, bracing and cladding thickness to meet higher cyclonic design requirements.
