Hay, Machinery or Livestock? How to Pick the Right Farm Shed for What You’re Storing

If you’re in the market for a farm shed, the first question to answer isn’t about size or colour. It’s about what you’re storing.

The farm shed you need depends entirely on whether you’re housing hay bales, heavy machinery, or livestock, because each one has completely different requirements.

This farm shed buying guide in Australia walks through the three main use cases, what each one needs, and how to match your situation to the right size and style.

Storing Hay? Here’s What Actually Matters

Hay storage sounds simple until you end up with spoiled bales and mould problems because the shed didn’t breathe properly. A poorly ventilated hay shed can raise internal temperatures enough to cause spontaneous combustion in tightly packed bales. It’s a fire risk, not just a quality issue.

Getting ventilation, height and access right from the start saves you money and keeps your shed safe. Here’s what to nail:

• Ventilation: Open bay sheds or raised clearance walls let air move naturally through the structure, preventing moisture build-up and heat damage.
• Internal height: If you’re stacking bales with a loader, 4.5m to 5m internal height gives you safe working clearance.
• Capacity planning: Allow 1.5 to 2 square metres per large round bale. Storing 200 bales? You’re looking at a 300m2 floor plan. A 9x30m shed covers that with room to move.
• Access: Roller doors 4.2m or wider let you run a tractor or loader in and out without the entry becoming a bottleneck.

Recommended size range: 9x12m through to 9x30m, depending on bale count and stack height.

These sizes are a starting point. Best Sheds can design sheds to whatever dimensions your property and operation actually need.

Machinery Sheds: Size It for Your Biggest Piece of Equipment

Before you spec anything, measure your largest piece of equipment, including mirror width, and add at least 600mm to 800mm each side for a comfortable entry. Headers with the draper extended can easily push past 12m wide.

What to plan for:

• Door width: Plan for 6m to 8m wide roller doors as a minimum for modern farm machinery. If you’re housing a header, go wider.
• Door height: A standard header with a grain bin sits at around 4.2m. Add a GPS aerial or high-clearance sprayer coupling and you’re pushing 4.5m or more. Build to 5m and you won’t need to revisit this.
• Floor space and turning radius: Account for extra width so you can drive in, turn, and park without it becoming a ten-point manoeuvre.
• Lean-to bays: A lean-to off the main shed is practical for undercover maintenance, parts storage, or keeping a ute out of the weather.

Recommended size range: 7.5m to 12m wide, with length depending on how many machines you’re housing.

Sizes vary. Best Sheds engineers every shed to order, so yours can be built exactly to your specs.

Livestock Sheds: Comfort, Safety and Separation

Livestock sheds have different priorities to hay and machinery storage, and the design needs to reflect that. Whether you’re housing cattle for calving, sheltering horses, or managing animals through winter, the focus is on animal welfare and day-to-day practicality.

Key things to get right:

• Ventilation: Open bay designs with adequate roof height improve airflow and reduce respiratory problems in your herd.
• Drainage: A concrete floor with falls and drainage channels keeps the shed workable. Wet, poorly drained floors are the leading cause of hoof disease and mastitis in housed cattle, two conditions that cost significantly more to treat than a better floor costs to pour.
• Separation: Keep livestock away from hay and machinery storage for biosecurity, fire safety, and simpler management.
• Animal safety: Smooth internal finishes, no sharp protrusions, and well-planned pen layouts protect both your animals and the people working with them.

Recommended styles: Open bay and American barn styles work well for livestock, with good natural airflow and flexible internal layouts.

What About Arenas?

If horses are part of your operation, a covered arena is worth planning alongside your other farm infrastructure.

A standard competition arena runs 20x60m and needs at least 5m of internal clearance for safe jumping work, dimensions that require proper engineering rather than a standard shed spec. Best Sheds designs and supplies custom arena structures to suit your property and discipline.

How to Future-Proof Your Farm Shed

The most common mistake when ordering a farm shed is sizing it for today instead of planning for tomorrow. A hay operation running 150 bales this season might double in three years. One equipment upgrade can make a shed that felt generous feel tight overnight.

A few things worth thinking through before you finalise your spec:

• Will your storage needs grow? Sizing up upfront is almost always cheaper than adding on later.
• Are you upgrading equipment soon? If there’s any chance you’ll move to a wider header or add a chaser bin, factor that into your door width now.
• Do you need separate zones? Mixing hay and machinery in one shed works until it doesn’t. If you think you’ll eventually need separation, spec the size to accommodate that from the start.
• What access will you need around the shed? A concrete apron in front of your roller doors is worth planning at the same time. Far easier before the shed goes up than after.
