Spacious 8x8 Greenhouse with Thermal Insulation for Harsh Australian Conditions

6mm Twin-Wall Polycarbonate for Year-Round Climate Stability

This 8x8ft greenhouse uses 6mm premium-grade twin-wall polycarbonate glazing. With insulation that outperforms glass, it helps moderate internal temperatures and reduces plant stress from heat or frost. UV-protected on both sides for durability in Australian sun.

Strong Powder-Coated Aluminium Frame with Ventilation

The matt-black aluminium frame is powder-coated to prevent rust and withstand harsh outdoor environments. Two roof vents are included for improved airflow and humidity control — key to keeping your plants healthy in warm weather.

Designed in New Zealand. Assembled in Australia.

Manufactured in New Zealand and assembled locally, this glasshouse 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.

At 2596mm wide x 2596mm long, this 8x8 model provides enough space for raised beds, shelves, or staging — without dominating your backyard. It’s ideal for hobbyists, veggie growers, and collectors looking for a climate-stable space to grow.
