10 x 20 ft Greenhouse for Serious Growers Who Need Space and Thermal Efficiency

6mm Twin-Wall Polycarbonate for Insulation and Plant Protection

This 10x20ft greenhouse features 6mm twin-wall polycarbonate glazing that offers excellent thermal performance, shielding plants from frost and harsh sun. The diffused light promotes healthy growth while maintaining a more stable internal environment across all seasons.

Expansive Layout and High Roof for Efficient Workflow

With internal dimensions of 3220mm wide and 6386mm long, the structure provides ample space for propagation, plant staging, raised beds, and walkways. The tall 2850mm roofline improves airflow while allowing room for trellised crops or vertical shelving.

Designed in New Zealand. Assembled in Australia.

Manufactured in New Zealand and assembled locally, this greenhouse is purpose-built for Australian conditions. Unlike many imported kits designed for milder climates, Winter Gardenz structures are engineered to handle the extreme weather seen in regional and coastal Australia — from strong winds to temperature swings.

Award-Winning Design and Rust-Proof Frame

The frame is built from powder-coated matte-black aluminium, offering exceptional durability and corrosion resistance. Combined with a streamlined modular design, it’s easy to assemble and built to last.

  • Dimensions: 3220mm (W) x 6386mm (L) x 2850mm (H to ridge)
  • Height to gutter: 1620mm
  • Glazing: 6mm twin-wall polycarbonate (UV-protected both sides)
  • Frame: Matt-black powder-coated aluminium
  • Wind Rating: Up to 150km/h when installed to specification

Awesome.
Color: Silver Blue Brown
Loved it! I can hardly hear it run, its so quiet! It's very easy to read and looks quite classy. The leather strap has also held up very well to normal wear.

A Great Value for the Time
Color: Rose Gold Black
Beautiful watch that looks far more expensive than it is. The rose gold finish is very attractive, and the black faux leather band goes well with it. It tells time accurately. The only caveat is the date window which is so tiny that it's very difficult to read when not under direct light. I am very pleased with my purchase.

Nice watch!
Color: black/black
This watch was very easy to set and keeps time very well. It looks great with a professional appearance it seems to be well built and the warranty is good. The glass on the first one I got cracked after two months and they are sending me a new one!

Great value!
Color: black/black
Great value for the money. My teenage son started a watch collection, and this was the perfect addition. It looks like it cost a lot more than it really did.
