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

Bad holes
Poles 1 and 2 don't click together due to poorly drilled holes, the clicker and the predrilled holes don't line up, really should return, but it's for outside, may try to fix the holes with a drill

Quick and easy assembly
This room divider is quick and easy to assemble, and does a great job at providing coverage with its large dimensions. The construction is sturdy and the divider material provides great privacy. This divider is relatively lightweight but despite just the two legs and somewhat large size, it's quite stable.

Quickly Assemble
This can quickly be assembled. It has a sturdy metal frame and the fabric is thicker and you cannot see through it.

Decent Divider/Backdrop from the price.
This divider w tricky to put together with some of the parts not seeming to fit well, but it DID go together with some effort and patience. The backdrop material is thin and while not the best quality doors what it’s supposed to do. I like the neutral gray color as it t blends with everything. I can also hang other backdrops from the frame. Overall very pleased with this.
