Built around a strong aluminium frame and glazed with traditional 3mm horticultural glass, the ICON 6 combines durability with excellent light transmission for everyday growing. The low-threshold sliding door allows easy access for trays, compost, and tools while preserving valuable internal space. Ideal for gardeners upgrading from a smaller structure or establishing a productive growing area, this model offers a reassuring balance of usability and long-term performance.

Frame colour and glazing options available 

Select from a range of frame finishes and glazing types to suit both your garden style and growing needs. Powder-coated green and black frames are available alongside the classic mill-finish aluminium option. Each finish is corrosion-resistant and designed to protect the aluminium structure while enhancing appearance. The green frame blends naturally into traditional gardens, while mill aluminium offers a clean, neutral look with minimal maintenance requirements.

Glazing options allow you to tailor the greenhouse to your preferences.
3mm horticultural glass provides excellent clarity and maximum light transmission, making it ideal for seed sowing and general plant growth. 3mm toughened safety glass offers increased strength and peace of mind for family gardens or more exposed locations. 4mm Polycarbonate glazing is also available for those seeking improved insulation and diffused light.

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, bases may be included as part of a special offer. If that applies, the option can simply be selected at zero cost when ordering.

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.
