Getting To Know The Kiwi MK3A
Two Tone Colour Options
Kiwi full timber framed garden sheds are available in a wide range of colours giving you the opportunity to mix and match the wall and trim colours.
Single Colour options
Kiwi full timber framed garden sheds are available in a wide range of colours, including these single colour options.
Full Timber Frame
A machine-finished timber frame forms the backbone of our garden sheds. The timber gives added rigidity and strength and is interlocked at the corners to form an extremely robust structure.
Traditionally sheds have relied on nuts, bolts and screws to hold them together. Duratuf Fortress sheds however are constructed with the cladding fixed securely to the frame using galvanised nails - just like a garage. This braces the structure and gives the added strength needed to last that extra distance.
We have the corner joins covered as well!
Instead of the conventional overlapped corners (Fig. 6), Kiwi shed corner joins (Fig. 5) are completely covered by a modern looking flashing making them extremely weather-tight and child safe.
Advanced Water Run Off
Surely everybody wants a weatherproof garden shed? It’s important then, that water flows away from your shed to ensure your valuable gear is kept dry. The unique design of our sheds ensures that water is not trapped on or around them.
Duratuf timber frame sheds feature a unique construction method where the cladding is nailed to the top and bottom plates. This method ensures that water runs away from the shed easily as there are no channels to trap leaves, dirt and water that will leak, or sit and corrode the cladding. (Fig. 1)
Conventional shed designs require a channel at the top and bottom of the shed to hold the cladding together. (Fig. 2)
Fortress kitsets can be modified to allow the wall cladding to extend past the base of the shed when placing on a raised concrete floor. This completely eliminates the possibility of water running back into the base of your shed.
0.4mm Hi-Tensile Cladding
Duratuf Fortress garden sheds are manufactured from strong hi-tensile .40 gauge steel, roll formed into an attractive 6-rib profile and are available in a Zinc / Aluminium finish or in a range of popular colour coated options. And because we are so confident in the quality of our cladding, we back it up with a full 30 year warranty (conditions apply).
Superior NZ Made Quality
When you invest in a Duratuf garden shed, you are investing in a New Zealand made quality product that you can rely on.
Manufactured on home turf means that the product is suited to New Zealand conditions. Further to that, only the best materials are used, from NZ grown timber through to premium hi-tensile steel and quality fastenings.
Keeping Kiwis in jobs plays an important role in our community and gives the added assurance of controlled quality
during manufacture, coupled with a locally backed warranty - we’ll be here if you need us!

Solid Timber Floor Kit
Duratuf Timber floor kits create a strong, level working platform that fit inside the shed and on top of the bottom plate, not underneath like other garden sheds. This has a number of advantages.
• It creates a level access into the shed.
• The cladding extends past the floor level and stops water leaking back into the shed.
• The extra weight inside the shed provides exceptional hold-down ability.
The kit includes everything that you need including thick gauge timber floor boards, ground treated H4 joists, galvanised nails and an attractive doorway flashing.
Raised Floor Modification
The unique design of Duratuf timber frame garden sheds allows them to be adapted using the Raised Floor Modification. This makes the cladding protrude 20mm below the base plate. Any water running down the wall cannot flow into the shed ensuring a dry, weather-tight floor.
If building a raised concrete pad for your Fortress garden shed you do not need to order the Raised Floor Modification as this can simply be done when assembling the shed.
Building A Concrete Floor Option
Step 1 - Establish the size of the shed and excavate a sufficient area. Remember to allow for a rear roof overhang of 80mm and 30mm for end walls.
Step 2 - Ensure that the base substrate is compacted firmly. We suggest that the slab should be 80mm thick in the middle and 100mm thick around the edges (Fig 2).
Step 3 - Lay boxing to the required size. The raised slab size should be 15mm smaller than the overall base size of the shed and at least 30mm above the ground line. See Fig. 1
Step 4 - Lay plastic sheeting if required. Plastic sheeting under-slab will prevent moisture from coming through from underneath.
Step 5 - Pour concrete and screed flush.

All hardware is provided including galvanised cladding nails, rivets and weather seal nails for the roof.

Extra Wall Height
All Fortress garden sheds feature a generous 1.9m wall height as standard, however there are times when a little extra head height can come in handy. Now you can have the option of 200mm extra wall height!
If you feel that a little extra head height would be a luxurious advantage, Fortress sheds can now be modified easily to give you that extra height you need. This not only creates a feeling of spaciousness, but gives more room for taller people to move around freely. It also gives more capacity to hang tools or shelving, and to maximise storage of tall objects.
The increased Head Height Option is also ideal in a workshop situation, allowing more room to move when working at a workbench, as well as providing some added space to install lighting. Surcharge applies.
Clear Roof Panel
Duratuf Clear Roof Panels provide UV free natural daylight, ideal for a workshop situation.
For gable roof sheds, choose from either single or double clear panels (one side or both sides of the central ridge beam).
Please note that clear panels may condensate more than steel.

Raised Floor Modification
The unique design of all Duratuf sheds allow them to be easily modified for use with a raised concrete pad.
The modification causes the wall cladding to overhang the concrete floor slab, which creates excellent weather-proofing, something that can't be done with non-timber framed garden sheds.
