Large 8x12 Greenhouse with Thermal Efficiency and Superior Airflow

6mm Twin-Wall Polycarbonate for Year-Round Temperature Control

This 8x12ft greenhouse is fitted with 6mm premium twin-wall polycarbonate panels. The insulated glazing diffuses harsh light, retains warmth during colder months, and reduces heat gain in summer — all while protecting plants from UV damage on both sides.

Extra Ventilation and Durable Frame for Harsh Conditions

With four roof vents included, this model provides excellent natural airflow to prevent overheating and regulate humidity. The rust-resistant aluminium frame is powder-coated in matte black for long-lasting strength and sleek aesthetics.

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.

Spacious Interior for Dedicated Growers

At 2596mm wide x 3844mm long, this 8x12 model offers plenty of space for raised beds, multiple staging levels, and propagation setups. It’s a great choice for home growers who want serious output with the control and protection of an insulated structure.

  • Dimensions: 2596mm (W) x 3844mm (L) x 2615mm (H to ridge)
  • Height to gutter: 1620mm
  • Glazing: 6mm twin-wall polycarbonate (UV-protected both sides)
  • Frame: Matt-black powder-coated aluminium
  • Roof vents: 4 included for improved ventilation
