A smart step up in space and performance: the Halls ICON 6 6x6 4mm polycarbonate greenhouse in a mill finish for a stable, insulated growing environment
The Halls ICON 6 6x6 greenhouse delivers a perfect balance between compact garden footprint and generous growing space. Its square layout provides ample room for staging shelves, tending plants, and moving around without feeling cramped, yet it still fits neatly into most family gardens. The improved headroom and airflow create a calm internal environment where everyday gardening tasks feel relaxed and efficient. Built around a resilient aluminium frame and glazed with 4mm twin-wall polycarbonate glass, this greenhouse combines strength, insulation, and thoughtful design. The low-threshold sliding door enables easy access for trays, compost, and tools while preserving valuable internal space. Ideal for gardeners stepping up from smaller models or looking to expand productive growing areas, this greenhouse offers reliable year-round performance with a low-maintenance finish
Frame colour and glazing options available
The ICON 6 greenhouse range is available in black or green powder-coated aluminium frames for corrosion resistance, or a mill aluminium finish for a clean, low-maintenance look. The mill aluminium frame on this model provides a neutral finish that suits both traditional and modern gardens.
Glazing options across the ICON 6 range include 3mm horticultural glass for clear light transmission, 3mm toughened safety glass for added strength, and 4mm twin-wall polycarbonate glazing for improved insulation, diffused light, and greater impact resistance in harsher conditions.

Frequently asked questions
Do I need a base for my greenhouse?
In most cases, yes, a base is strongly recommended. A purpose-made greenhouse base makes installation far easier, ensures the structure sits level, and provides long-term stability. This helps protect both the frame and the glazing over time.
If your greenhouse is being installed onto an existing solid surface such as a concrete pad, brick base, or wall-mounted foundation, you may not require a separate steel base. However, where no suitable foundation already exists, a proper base is the safest and most straightforward option.
Occasionally, a base may be included free of charge as part of a special offer. If this applies, there is no need to add a base to your order—it will be supplied and shipped automatically with your greenhouse.
Do I need professional installation?
All greenhouses are supplied with full instructions and many customers do successfully install them themselves. However, installation does require time, careful preparation, and suitable weather conditions. Many customers choose professional installation for added convenience and peace of mind. If you do opt for installation for your Icon 6 greenhouse, it is essential that the area is fully prepared ahead of time. This means the ground must be level, clear of debris, and easily accessible for the installation team.
