A low-threshold sliding door ensures easy movement of trays, compost, and tools while preserving the full internal growing area.

Why the ICON 6 6x8 is easier and safer to use

3mm horticultural glass for healthy plant growth

The 3mm horticultural glass provides strong, natural light to help seedlings, vegetables, and tender plants thrive, while maintaining the classic greenhouse look and feel.

Extended footprint for more space and organisation

The larger 6x8 size gives you more room to move around, fewer bottlenecks, and better internal flow, making it ideal for tending multiple trays, rearranging staging, or working with taller plants.

Mill aluminium frame for low-maintenance durability

The clean mill aluminium frame resists corrosion and fading, providing a neutral, long-lasting finish that blends naturally into any garden style.

Higher eaves for improved comfort and airflow

Increased internal height creates a more open feel, enhances ventilation, and makes everyday tasks such as watering, potting, and plant care more comfortable.

Low-threshold sliding door for easy access

The smooth-glide sliding door preserves internal space while making it simple to move trays, tools, and compost in and out safely.

Stable roof and structure for dependable performance

The reinforced aluminium frame and optimised roof pitch ensure reliable performance in a variety of UK weather conditions, giving peace of mind year-round.

Integrated guttering for controlled rainwater collection

Wide gutters are ready for connection to optional 40mm downpipes, making it easy to harvest rainwater and maintain a sustainable growing setup.

 

Create A Complete Growing Setup With Optional Add-Ons

Create a complete growing setup by enhancing your Halls ICON 6 6x8 Greenhouse with optional accessories at the point of purchase. Secure your greenhouse with a galvanised steel base plinth, add a downpipe kit and waterbutt and stand to collect rainwater, or improve airflow with a louvre vent kit. Choose capping for added durability or decorative cresting for a classic finishing touch. You can also add folding modular staging and shelving, designed to fit neatly inside the 6x6, 6x8, and 6x10 models, giving you flexible, space-saving storage for plants, trays, and gardening tools.

 

Who the ICON 6 6x8 greenhouse is best suited to

Designed for gardeners seeking more room without stepping up to a very large structure. Ideal for seed propagation, growing vegetables and herbs, larger pots, or overwintering plants. Its extra length ensures daily tasks feel practical and relaxed, especially when upgrading from a 6x4 or 6x6 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.
