Best For

Serious home gardeners, hobby farmers, and those in colder Victorian regions who require a large, permanent-style walk-in structure with superior corrosion resistance.

Key Features

• ✔ Corrosion-Resistant Galvanised Steel: Built with an exceptionally strong galvanised steel frame. Unlike standard painted frames, galvanisation provides a deep layer of protection against rust—essential for high-humidity greenhouse environments.

• ✔ Reinforced 140g/m² PE Cover: The heavy-duty green polyethylene cover is UV-resistant, frost-safe, and anti-tear. It’s designed to trap heat for "warm house" performance while acting as a rugged shield against wind and birds.

• ✔ 4-Window Ventilation System: Features four independent roll-up mesh windows (40 x 40 cm). This allows for precision cross-ventilation, preventing heat-stress and fungal issues during the humid autumn and spring months.

• ✔ Massive 8sqm Footprint: With a 4m length and a full 2m head clearance, this greenhouse comfortably accommodates multiple rows of garden beds, central aisles, and staging benches.

• ✔ High-Access Roll-Up Door: The 100 x 185 cm zippered door provides effortless "in-and-out" access, even when carrying large seed trays or maneuvering wheelbarrows.
