What makes the ICON 6 easier and safer to use day to day

Toughened safety glass that reduces risk

The 3mm toughened glass is more impact-resistant than standard horticultural glazing and breaks into small, blunt fragments if damaged. This improves safety during regular use while maintaining strong light transmission for healthy plant growth.

Higher eaves for better comfort and airflow

The increased eaves height creates a more open internal feel, improves airflow, and makes everyday tasks such as watering and potting more comfortable in a compact greenhouse.

Powder coated for lasting protection

As well as offering a stylish, modern finish, the powder-coat to the aluminium frame provides an extra layer of protection against corrosion and wear, helping your greenhouse stay strong and looking great for years with minimal maintenance.

Low threshold sliding door for easier access

The sliding door preserves internal space and reduces strain when moving in and out with tools, trays, or compost, supporting safe, practical daily use.

Stable aluminium frame with reduced maintenance

The aluminium structure resists weathering without the ongoing maintenance associated with timber frames, helping the greenhouse remain dependable over many seasons.

Secure glazing with less movement and condensation

The G-clip glazing system and integrated glass stops hold panels firmly, reduce vibration in exposed conditions, and help divert condensation to keep the interior cleaner and quieter.

Integrated guttering for controlled rainwater collection

Wide gutters are ready for connection to optional 40mm downpipes, allowing straightforward rainwater harvesting.

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. 

 

Who the ICON 6 6x4 greenhouse is best suited to

The ICON 6 is designed for gardeners who require a compact greenhouse that remains comfortable to use and dependable with regular use. It is suited to seed propagation, herbs, seasonal crops, and overwintering plants, providing a controlled growing environment without the cost or visual dominance associated with larger structures. Where higher production volumes or clearly defined growing zones are required, a larger model may be more appropriate [link to 6x6/6x10]. For most home gardeners seeking long-term value within a modest footprint, the ICON 6 represents a practical and reassuring choice.

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.
