See How Our Greenhouse Is Built
An independent YouTuber shows exactly how our greenhouse is constructed — no edits, no shortcuts.
Versatile Growing Space
Sleek aluminium finish blends well with contemporary gardens and backyards.
Ideal for vegetables, herbs, seedlings, and flowers in all seasons.
6mm Twin Wall
A twin wall is a common configuration in greenhouses, but the thickness of the panel varies. Our polycarbonate panels are 6mm thick, which sounds like a small difference than 4mm, but it creates 20% effectiveness in heat protection, 5-10% less light transmission. It will also last longer, especially in the variable climate of New Zealand.
Improved Wind Resistance With Door Lock
The greenhouse is able to withstand strong wind from the outside, however, if wind gets inside through the door, the greenhouse becomes vulnerable and some panels may be lifted off. For this new series of greenhouses,, we have added a door lock to keep the door securely closed.
Extensive Reinforced Bracing
Every panel has extra diagonal bracing behind their back, protecting them in severe weather conditions. There are also horizontal bracings added under the peak, which stabilize the structure of the whole greenhouse.
Stainless Steel Fasteners
Upgraded stainless steel bolts and nuts, they are rust proof as the aluminium profiles. It will support the greenhouse for many years to enjoy with peace of mind.
