What makes the ICON 6 practical and dependable day to day

Traditional horticultural glass for excellent light levels

The 3mm horticultural glass panels allow maximum sunlight into the greenhouse, supporting strong plant growth and even light distribution. This makes it a popular choice for seed propagation, cuttings, and general growing throughout the season.

Higher eaves for improved comfort

The raised eaves height creates a more open feel inside the greenhouse, improving airflow and making everyday tasks like watering and potting easier and more comfortable.

Powder-coated aluminium for long-term durability

Where powder-coated options are selected, the aluminium frame benefits from an extra protective layer that resists corrosion, scratching, and general wear, ensuring long-lasting performance with minimal upkeep.

Sliding door designed for efficient access

The smooth-gliding sliding door saves space and allows easy movement in and out of the greenhouse, even when carrying tools, trays, or watering equipment.

Low-maintenance aluminium structure

The aluminium frame requires no painting or treatment and stands up well to changing weather conditions, offering dependable performance season after season.

Secure glazing with reduced movement

The G-clip system and integrated glass stops hold the horticultural glass firmly in place, reducing rattle in windy conditions and helping guide condensation away from growing areas.

Integrated guttering for rainwater collection

Wide, built-in gutters are ready to accept optional 40mm downpipes, making rainwater harvesting straightforward and efficient.

Optional add-ons to create a complete setup from the get-go

The Halls ICON 6 greenhouse is highly customisable, allowing you to create a complete setup with everything you need. You can enhance practicality with a waterbutt and stand, downpipe kit, and louvre kit for added ventilation. You can also elevate its appearance with traditional greenhouse cresting, and improve durability with sleek capping for a stronger, more elegant finish. This flexibility lets you tailor your greenhouse to your gardening style and aesthetic.  *Additions can only be purchased at the same time as purchasing your greenhouse.

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.
