Building A New Woolshed In NZ

For generations, the humble woolshed has stood the test of time in the countless farms and high-country stations all the way from Northland, down through the mighty Waikato and Bay of Plenty, across to the Hawkes Bay, and down to the South Island's Canterbury Plains and beyond. Inextricably linked to New Zealand’s sheep farming heritage, even today the humble woolshed remains a necessity for the nation's sheep farmers.

Why Wood Endures In NZ Woolsheds

Visit any sheep station in New Zealand, and you'll inevitably find magnificent old woolsheds, many of them built entirely from timber. From the earliest settlers, timber was the natural choice – abundant, versatile, and relatively easy to work with. Some over a century old, these structures stand as a testament to timber's incredible durability when properly constructed and maintained.

Today, while steel and other materials have entered the construction landscape, timber continues to offer distinct advantages for not just woolsheds but all types of sheds that can’t be overlooked. Timber allows for a high degree of customisation. Whether you need specific layouts and catching pen designs, or unique wool handling and storage areas, timber-framed buildings can be easily adapted to suit your precise operational flow.

Timber-built woolsheds also offer a locally sourced eco-friendly build choice. New Zealand's timber industry is built on sustainable plantation forests, primarily Radiata Pine and Douglas Fir. Choosing timber means opting for a renewable resource with a lower carbon footprint compared to many other building materials. This aligns perfectly with the growing focus on sustainable farming practices.

4 Modern Woolshed Design Tips

A well-designed woolshed can positively impact productivity, wool quality, and the overall well-being of your livestock and your team. Here are the main things to consider when designing and building woolsheds for New Zealand sheep farms.

1. Optimise Layout And Flow

The efficiency of a woolshed hinges on its internal layout. Designs should focus on:

  • Stock Movement. Prioritise the natural, smooth, stress-free movement of sheep from the yards outside through to the woolshed holding pens and into catching pens. This includes careful consideration of ramp angles, gate placement, and pen sizes to minimise difficulty moving the sheep from one area to another and reduce handling times.
  • Shearer Ergonomics. The shearing board is the heart of the operation, getting the right mix of space, lighting, and ventilation, plus operational efficiency, are the priority here. Ensure there is plenty of space between each shearing stand, and most importantly, that the board surface is non-slip for the shearers yet easy to work with for the shed hands (sheep are able to be dragged easily and wool is able to be swept without catching).
  • Quality Wool Handling. A spacious, well-lit, and central wool room is best for efficient wool handling and pressing. You will need adequate room for sorting, the wool press, and easy storage of wool bales.
  • Accessibility. Easily accessible loading bays are necessary for wool trucks when loading up the wool bales, the loading area must be well incorporated into the design as part of the overall site plan.

2. Durability And Materials Matter

From the chilling southerlies of the South Island to the humid conditions of the North, NZ’s climate demands durable and resilient buildings. Timber-framed woolsheds must be built to withstand the challenges of everyday wear and tear and include:

  • Treated Timber. Woolsheds are built to last, high-quality treated timber (H3.2 or H4, depending on exposure) for ground contact and external use is needed for protection against rot and decay, ensuring a long lifespan.
  • Robust Foundations. Solid foundations are non-negotiable. Woolshed foundations must be engineered to support the structure and withstand ground movement and moisture.
  • Roofing And Cladding. Most NZ woolsheds are built with corrugated iron roofing and cladding for longevity, durability and affordability.
  • Flooring. Grated timber flooring is used in catching pens (allowing waste to fall through) and stronger hardwood flooring is preferred for the shearing board. The wool room flooring is generally composite flooring sheets with a smooth finish suitable for sweeping the wool.

3. Safety And Compliance First

Safety in the woolshed is a top priority for both farmers and shearers. All woolshed structures must comply with the New Zealand Building Code and integrate best practice safety measures. These include building consent from your local council. Ensuring all plans meet the necessary regulations for structural integrity, fire safety, and environmental considerations. Please note that there are specific exemptions and requirements for agricultural buildings in NZ.

Woolshed safety and compliance also includes designing for good ventilation, sufficient lighting (both natural and artificial), clear pathways, non-slip surfaces, and safe access to all work areas. The "ShedSafe" initiative, while originating from Australia, offers excellent guidelines for creating a safe shearing environment, and it is wise to incorporate these principles into your design. Designs need to prioritise sheep movement, minimising stress and injury. The use of appropriate fire-rated materials is also necessary as adherence to building codes can mitigate risks.

4. Customise And Future-Proof

A new woolshed is a significant investment, it needs to serve the farm for decades to come. So it is important to get it right the first time. Some of the more important factors to consider are:

  • Scalability. Can the shed be expanded or adapted in the future if stock numbers change or new technologies and techniques emerge?
  • Multi-Purpose Use. Can certain areas of the shed be used for other farm activities outside of shearing season, such as machinery storage, covered yards, or even a workshop? Integrating covered yards into the shed design is a common and highly effective way to maximise your investment.
  • Technology Integration. Planning for power points, lighting, and potential future automation or monitoring systems is always advisable.
  • Sustainable Features. Integrating rainwater harvesting systems for washing down, or designing for solar panel installation on the roof to offset energy costs could be worth implementing depending on the shed’s location.
