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

My dogs love their "keys".
Size: X-Small
My dog loves this. The only negative is that he does chew through it and I have to pick up the pieces or hope that he's not eating it.

Not long lasting for a chewer!
Size: Medium
These are massive! I have a golden retriever puppy and she chewed through the yellow ring very quickly. They keys are much more durable.

Great for puppies- have purchased several times
Size: X-Small
I have purchased this toy for a couple of the puppies in my life and they always love it. It’s not noisy, it’s made for puppies to chew (so it’s not too hard), and it’s fun for them to carry around with the different keys and key ring. A little pricey, but it always lasts a very long time- longer than they are a puppy!

Safe and Entertaining Chew Toy
Size: Medium
My dog absolutely loves this toy! She gets hours of chewing time out of it, and I feel so much better knowing the keys are made of a material that’s gentle on her teeth. Unlike harder toys that can chip teeth, this one is durable yet safe, and it keeps her happily entertained. Definitely a great choice for any dog that loves to chew.
