Halls ICON 6 6x6 Greenhouse 4mm Polycarbonate - Black HR01051

Enjoy a practical and versatile growing space with the Halls ICON 6 6x6 Greenhouse

Upgrade your garden without feeling cramped with the Halls ICON 6 6x6. Its well-proportioned footprint gives you more room to nurture plants, organise shelving, and move comfortably, while still fitting neatly into most UK gardens. Improved airflow and headroom create a calmer internal climate, making it easy to care for seedlings, vegetables, and tender plants throughout the year. You get the convenience and efficiency of a larger greenhouse without it feeling overwhelming.

Built with a durable aluminium frame and insulated 4 mm twin-wall polycarbonate glazing, the ICON 6 6x6 balances strength, weather resistance, and thoughtful design. The low-threshold sliding door allows easy access for trays and tools, maximising internal space. Perfect for gardeners looking to expand from smaller models, this greenhouse combines reliable year-round performance with everyday practicality.

Frame colour and glazing options available

This model is finished in sleek black aluminium that provides excellent corrosion resistance and a contemporary garden aesthetic. Mill aluminium or powder-coated green finishes are also available across the ICON 6 range to suit different garden styles. Each finish is durable, weather-resistant, and low-maintenance.

This Halls ICON 6 6x6 features 4mm twin-wall polycarbonate glazing, which provides improved insulation, reduces heat loss, and diffuses sunlight to protect plants from scorching while maintaining a stable internal climate for year-round growing. For gardeners seeking a different look or performance, the ICON 6 range also offers 3mm horticultural glass, which delivers excellent light transmission and a classic greenhouse aesthetic, and 3mm toughened safety glass, which adds extra strength and peace of mind, particularly in family gardens or exposed sites. Compared with traditional glass, the polycarbonate panels are more impact-resistant and retain heat better, making them a practical choice for year-round growing.

What makes the ICON 6 6x6 easier and safer to use day-to-day

4mm twin-wall polycarbonate glazing for balanced growing conditions

The polycarbonate panels diffuse sunlight, improve insulation, and offer high impact resistance, creating a more stable and forgiving environment for seedlings, vegetables, and tender plants throughout the seasons.

Generous footprint for better organisation and movement

The 6x6 size gives you extra space to arrange staging, manage taller crops, and move comfortably without feeling crowded—making routine tasks feel more relaxed and efficient.

Durable frame with minimal maintenance

The corrosion-resistant aluminium frame requires very little upkeep, allowing you to focus on growing rather than maintenance.

High eaves for comfort and airflow

Increased internal height improves natural ventilation, making everyday tasks such as watering and potting more comfortable.

Low-threshold sliding door for practical access

Smooth-glide access makes it easier to move tools, trays, and compost in and out without losing internal space.

Stable roof and structure for dependable performance

A reinforced frame design with an optimised roof pitch provides reassurance in variable UK weather conditions.

Integrated guttering for rainwater management

Wide gutters are ready for optional 40mm downpipes, making rainwater harvesting easy and sustainable.

Optional add-ons to create a complete setup from the start

Enhance your Halls ICON 6 6×6 greenhouse with optional accessories available at the point of purchase, including a galvanised steel base plinth for secure installation, a downpipe kit and waterbutt and stand for rainwater collection, louvre vents for improved airflow, glazing capping for extra durability, decorative cresting for a polished finish, and folding modular staging and shelving for flexible storage inside the greenhouse. All accessories must be ordered at the same time as your greenhouse to ensure a complete, coordinated setup.

Additions can only be purchased at the same time as ordering your greenhouse.

 

Who the ICON 6 6x6 greenhouse is best suited to

This model is ideal for home gardeners who want a comfortable amount of growing space without moving up to a very large structure. It suits seed propagation, vegetable and herb growth, pot organisation, and year-round plant care. The extra room compared with smaller greenhouses makes regular use feel more practical and enjoyable, particularly for those upgrading from a 6x4 or compact greenhouse.

For gardeners seeking dependable performance, good insulation benefits, and a garden-friendly footprint that remains unobtrusive yet productive, the Halls ICON 6 6x6 presents a reassuring and practical 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.
