Halls ICON 6 6x8 Greenhouse 4mm polycarbonate - Mill HR 01089

Create a comfortable, practical growing space without overwhelming your garden with the Halls ICON 6 6x8 Greenhouse

Its balanced 6x8 footprint offers noticeably more room to grow, organise, and work than smaller models, while still fitting neatly into most family gardens. The extended layout improves airflow and headroom, creating a calmer internal environment where you can move freely, manage staging, and care for plants comfortably throughout the seasons, delivering the practicality of a generously sized greenhouse without feeling imposing or out of proportion.

Built with a durable mill-finish aluminium frame and insulated 4mm twin-wall polycarbonate glazing, the Halls ICON 6 6x8 combines strength, weather resistance, and thoughtful design. The low-threshold sliding door allows easy access for trays, compost, and tools while preserving valuable internal growing space. Ideal for gardeners upgrading from a smaller greenhouse or planning a more productive setup, this model offers reliable performance and year-round comfort.

 

Frame colour and glazing options available

Choose from a range of frame finishes and glazing options to suit your garden style and growing priorities. Powder-coated black and powder-coated green frames are available, each offering a durable, corrosion-resistant surface that protects the aluminium structure while enhancing appearance. The black finish complements modern garden designs, while the green frame blends seamlessly into traditional planting schemes. This mill aluminium version provides a clean, neutral look with minimal maintenance, ideal for gardeners who prefer a classic, understated finish.

Glazing options allow you to tailor performance to your needs. 3mm horticultural glass offers excellent light transmission and a traditional greenhouse aesthetic, ideal for seed sowing and general growing. 3mm toughened safety glass provides added strength and peace of mind, making it suitable for family gardens or exposed sites. This model features 4mm twin-wall polycarbonate glazing, which improves insulation, reduces heat loss, diffuses sunlight to help protect plants from scorch, and offers increased durability in harsher weather conditions.

What makes the ICON 6 6x8 easier and safer to use day to day

4mm twin-wall polycarbonate glazing for controlled growing conditions

The polycarbonate panels help retain warmth, reduce heat loss, and diffuse sunlight evenly, creating a more stable internal climate for seedlings, vegetables, and tender plants.

Extended footprint for better organisation and movement

The larger 6x8 size gives you extra room to arrange staging, manage taller plants, and move comfortably without congestion.

Mill aluminium frame for durability and low maintenance

The corrosion-resistant aluminium frame stays neutral in appearance and requires minimal upkeep, making it ideal for long-term use.

Higher eaves for comfort and airflow

Increased internal height improves ventilation and makes routine tasks such as watering and potting more comfortable.

Low-threshold sliding door for practical access

The smooth-glide sliding door allows easy movement of tools, trays, and compost while maximising internal growing space.

Stable roof and structure for dependable performance

The reinforced frame and optimised roof pitch provide reassurance in changing UK weather 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, 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.
