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

Silk pillow cases that are a stitch above
Color: Beige, Size: 2 Pack Standard(20"X 26")
These pillow cases are amazing. My family loves them. Great quality. They can be machine washed. I have purchased the more expensive brands but these are made from the same silk and have the same features like a hidden zipper for a fraction of the cost. They come in a variety of colors which is also an added bonus.

So cozy!
Color: White, Size: King, Color: White, Size: King
I absolutely love this comforter! It's very cozy, soft, and fluffy! I bought it for a duvet that I have and it fits it perfectly. It has loops on all four sides to tie a duvet and comforter together, which is really helpful. This comforter is also breathable so it helps me sleep better at night because I'm not getting overheated. The color and appearance is true to the pictures it displayed. It also seems to be quite durable and good quality. I would definitely recommend for anyone needing a new cozy comforter!

Must have!
Color: Light Grey, Size: Queen
⭐⭐⭐⭐⭐ This comforter is absolutely amazing! It feels like something you'd find in a luxury hotel—soft, lightweight, airy, and incredibly comfortable. It has quickly become one of the best purchases I've made. The quality exceeded my expectations, and it's perfect for staying cozy without feeling too heavy. My kids love it so much that they're constantly trying to steal it from me! If you're looking for a comfortable, high-quality comforter, I highly recommend this one. You won't be disappointed!
