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

Indestructible for the heavy chewers in your life!
My dogs can chew anything, and these are still in great shape! Very chew resistant to even my large dogs, and they love them! Easy to wash off if they end up in the food bowl or outside!

Not sure yet?
Only have had these for 24 hours but also purchased a couple other chew toys from Amazon as well and all were delivered at the same time. Point being that my #60 silver lab was trading off between all of them and after 2 hours only you can see little shards of plastic sticking up from these chews. Not sure how long these will last before having to throw them away but they are pretty nice and feel heavy and durable. So many of these companies claim they are “indestructible” but all 4 I purchased have little plastic pieces sticking up already. Even my #14 Shih Tzu enjoyed trying to chew these and it kept her busy even though they are for larger dogs.

Golden approved
My golden retriever’s really enjoy these chew toys. They are pretty durable and last awhile. They are hard plastic but they do get rough edges after they’ve been chewed in for awhile

Perfect for chewy doggos
My dogs loved them! Keeps them entertained for a few mins. You can also fill with PB and freeze. Or yogurt and freeze. Great for the doggos
