TUMU offers a range of engineer designed, high quality industrial, purpose built, standard gable and lean-to pole sheds. Built using NZ grown timber, they’re versatile, cost-effective and reliable.
Our designs have been proven over many years of exposure to the extremes of the New Zealand climate.

Recent advances in engineered wood products, like LVL (Laminated Veneered Lumber) offer you an alternative to traditional solid timber and / or steel as a clearspan construction material.

The benefits of building with timber and engineered wood products include:
• High fire rating and earthquake resistance to keep people safe.
• Carpentry based construction materials for cost-effective builds.
• Structures can be made bird-proof.
• Timber absorbs sound - ideal for production environments.
• Easy to adapt, alter or expand if your requirements change.
• Stylish, natural and environmentally friendly.
• 100% NZ grown and manufactured from renewable resources.

Flexible options to get your perfect building or shed

Every site is different, and every building or shed has a different purpose. That’s why our products have flexible options, so they can be customised to suit your needs.

After your initial contact, we’ll visit you for an on-site consultation to discuss what can be achieved within your budget. Initial designs use standard bay widths, depths and heights to make the best use of construction materials, but these can be adapted for the specific purpose of your building or shed. You’re welcome to take advantage of our building experience to get ideas and find solutions.

You’ll soon see there are plenty of options when it comes to customising your building. We’ll work with you to achieve the right mix of design to value for money, backed by the TUMU assurance that it will be built tough and made to last.

All custom structures are engineered to your specific site. We can take care of the whole building process or connect you with a building professional. If ‘purpose built’ is what you need, talk to us about turning your ideas into reality.

Quality construction materials for a tough building or shed

We know that sometimes, in farming or industry, your building might take the odd knock, and that the New Zealand weather will test its toughness year after year. That’s why we use good quality construction materials in every aspect of your building.


Timber is an easy product to work with, making it a ‘friendly’ carpentry based construction material, which doesn’t require engineering to be adapted to tiny discrepancies on site.


Advances to engineered wood products, like LVL, have allowed us to offer greater spans in timber construction as an alternative to an ‘all steel’ structure.

We also only use NZ manufactured cladding, such as Colorsteel, zincalume, and ply. The details matter and come as standard, like strong poles treated to last, and high quality galvanised fixtures and fastenings.

Like our building designs, construction options are flexible, including materials only, kitset, and fully project managed, concept to completion builds.

If your building or shed carries the TUMU name, you can rest assured it was built with the best quality materials, that are 100% NZ grown and manufactured from sustainable sources.
