10 x 20 Balance Greenhouse (3.1m x 6.1m)

10 x 20 ft Balance Greenhouse – Maximum Space for Serious Backyard Growing

Extra-Large Walk-In Greenhouse for Vegetables, Fruit & Herbs

This 10 x 20 ft walk-in greenhouse is designed for gardeners who want generous growing space and reliable year-round protection. The wide footprint and tall internal height make it easy to plant, maintain, and harvest vegetables, fruit, and herbs while still allowing room for benches, shelving, and garden tools.

Reinforced Aluminium Frame with Full Anchoring System

The structure features a rust-resistant aluminium frame with extra reinforced support beams for added strength. A galvanised steel perimeter base provides alignment and stability, while the integrated internal anchoring system and included external anchoring kit help secure the greenhouse during strong winds and harsh weather conditions.

Polycarbonate Panels for Light Control & UV Protection

Crystal-clear polycarbonate wall panels allow high light transmission while blocking harmful UV rays, supporting strong and consistent plant growth. Twin-wall polycarbonate roof panels diffuse sunlight to reduce heat stress and help maintain a more stable internal climate throughout the seasons.

Ventilation, Water Collection & Everyday Practicality

Four manually adjustable roof vents allow control over airflow, temperature, and humidity. Built-in gutters and outlets support rainwater collection for sustainable irrigation. Wide, high hinged double doors with a low threshold make access easy for wheelbarrows, plants, and equipment.
