Made using high tensile steel, our triple garages are a perfect solution if you need to store multiple cars along with bikes & boats.
Need a three-car garage?
If you’re looking for a storage solution to store and protect your cars, bikes, and boats, then you need a Wide Span Sheds triple garage! Also known as a three bay shed, these sheds have so much space you really can cram in multiple vehicles, tools, benches, equipment, and household items.
As with all our steel kit garages, you can adjust the height to ensure you have the ideal access for your vehicles and watercraft, as well as the length and span to perfectly fit the available space on your property. If you need extra storage or workshop space you can always include additional bays, carport extensions or a lean-to.
If you can imagine a design, fair chance we can create it. Contact us today to discuss your requirements.

Designed to your needs
Don't settle for less - design your shed exactly the way you want it! Wide Span Sheds are made to order, reflecting your unique requirements and style.
Customise every aspect:
Size
Size
We can customise your shed to fit your exact size preferences, providing design flexibility in increments as small as 100mm.
Your shed can span up to 25 meters, have bays up to 6m, lengths up to 200 meters, and eave heights up to 6m if required. We can also accommodate uneven bay widths.
Options for additional space
Increase floor space and add storage capacity in your shed with a mezzanine floor.
They provide an efficient means of maximizing floor space within your shed without expanding the footprint of your structure.
Please note: Mezzanine floors are not available for all sheds. Chat to our shed specialists about this option to see if it is possible to incorporate in your shed's design.

Roof style
Gable roofs are the most common roof style chosen for sheds. They have a classic profile with a high point in the centre, sloping toward the gutter on both sides of the apex.
Skillion roofs have a modern profile with a single pitch running from the high point on one side of the shed, to the low point on the other side.
Lean-tos
What is a lean-to?
A lean-to is a practical storage solution combining a standard enclosed shed with a non-enclosed section featuring an angled roof known as a lean-to.
Why choose a lean-to?
If you need extra space for vehicles or equipment that doesn’t require full enclosure, a lean-to may be the ideal solution. It offers protection from sun and hail and is more cost-effective than a full garage, as you're not paying for the front, rear, or sometimes side walls.
Please note: Not all sheds can include lean-tos. Chat with our specialists to see if it suits your design.
Skylights
Industrial strength fiberglass skylight roof sheeting brings natural light into your steel structure with ease. Designed to withstand industrial environments, these durable panels ensure longevity while enhancing your space.
By harnessing natural light, skylights can help reduce energy costs associated with artificial lighting. They promote a healthier indoor environment by providing ample natural light, which has been shown to improve mood and productivity. The installation of fiberglass skylight roof sheeting can also enhance the aesthetic appeal of your steel structure, creating a modern and inviting space.
Solar panel engineering
Adding solar panels increases roof load, wind resistance, and compliance requirements. Wide Span Sheds provides engineering solutions to support solar installations from the outset.
Why it matters:
- Council compliance: Updated building codes mean councils now scrutinise rooftop solar more closely. Design with compliance in mind to avoid costly changes later.
- Insurance: Roofs not designed for solar may face insurance issues. Proper engineering from the start improves insurability.
- Cost efficiency: Retrofitting for solar later is expensive. Future-proof your shed during initial design.

Insulation
We supply all of our sheds with roofing paper and offer the optional add-on of COLORSTEEL® DRIDEX® cladding. Dridex® combines a thin layer of a specialised absorbent fleece to the underside of the COLORSTEEL® sheet, negating the need for traditional underlay roofing and cladding paper. COLORSTEEL Dridex® absorbs accumulating moisture from the roof cavity and then releases it when conditions improve, delivering superior condensation absorption and enhanced ventilation.
Vermin proofing
We provide metal vermin flashings on all sheds supplied to guard against unwanted vermin entering the building between the sheeting profile and the concrete slab. Vermin flashing are a folded metal flashing connected to the inside of the wall sheeting, and continuing over the slab to eliminate the possibility of vermin entering the building after construction.
Sheeting profiles

ShedSafe Accredited
How is this done?
At Wide Span Sheds our team will assess the design needs of your building including:
- Wind Region
- Surrounding Terrain
- Topography
- Snow loading
- Earthquake loading
- Rainfall intensity
This is all taken into account in every single quote we do. We consider the above in combination with the intended use of the building. From this we can establish the required wind speed for your shed, to ensure it is fit for purpose.
Why is it important?
A properly designed building gives you the peace of mind that your property and those you value, are safe and secure. All our building designs are reviewed by our trained classification experts, before your plans and council documents are released. This process ensures we supply the right building, for the right site, at the right price. This means:
- Ease of Council approval / certification
- Insurance compliance

Frequently Asked Questions
What is the standard size of a triple garage?
A triple garage typically provides enough space to comfortably house three vehicles. At Wide Span Sheds, dimensions are fully customisable, so you can adjust width, depth, and height to suit your exact needs.
For reference, the standard size of a double garage in NZ is around 6m wide x 6m deep x 2.4m high, which fits two average cars. A triple garage generally extends this footprint, offering extra width and depth for a third vehicle or additional storage.
If you own larger vehicles, boats, caravans, or machinery, you’ll need to plan for additional height and clearance:
Large SUVs / 4WDs: At least 2.4m door height
Boats on trailers: 2.7m–3.0m door height
Caravans or motorhomes: 3.0m+ door height with roof clearance
Tractors / machinery: Measure tallest point (incl. attachments) and add 300–500mm buffer
Pro tip: Always measure your largest vehicle or equipment—including racks, antennas, and trailers—before deciding on dimensions. It’s more cost-effective to build larger from the start than to discover later your garage won’t fit.
Our Wide Span Sheds specialists can design your triple garage to suit both your current vehicles and your future needs.
How much does a triple garage cost?
The cost of a triple garage depends on size, design, and custom features. Extras like roller doors, insulation, windows, and roof styles can all influence the final price.
Site-specific factors—such as foundations, access, and local council requirements—also affect costs, so each quote is unique to your location and project.
As a guide, kitset triple garages in NZ generally range from $300–$600 per m² (kit only, excluding foundations and construction). Costs may increase with custom upgrades, extra engineering, remote delivery, and site-specific engineering for your site.
At Wide Span Sheds, we use NZ Steel designed for New Zealand conditions and back all garages with warranties of up to 50 years. Contact our team today for a tailored, no-obligation quote.
What materials are used in the construction of the triple garages?
Our triple garages are made using high tensile steel, known for its durability and ability to withstand harsh weather conditions. You can select from a range of COLORSTEEL® steel colours or ZINCALUME® finishes, ensuring both strength and aesthetic appeal.
Is the triple garage suitable for areas with extreme weather conditions?
Yes, all our triple garages undergo site-specific engineering to ensure they are designed to withstand local weather conditions, including high winds, heavy rainfall, and even snow loading. This ensures that your garage will be safe and durable, no matter where it’s located.
What types of doors are available for triple garages?
We offer a range of door options including roller doors, which can be motorised for convenience, and personal access (PA) doors for easy entry. Roller doors can be up to 5m wide by 5m high, and we also provide wind-locked roller doors for extra protection during storms.
Do I need council approval to build a triple garage?
In most cases, council approval is required to build a triple garage. Our team at Wide Span Sheds can assist with the necessary documentation and ensure that your garage design complies with local council regulations, making the approval process smoother.
