Make the most of your garden space without sacrificing usability with the ICON 6 6x4 greenhouse, featuring a powder-coated green frame and 4mm polycarbonate glazing system. Its modest size makes it a practical choice for smaller UK gardens, while also fitting naturally into larger plots where space efficiency still matters. The 6x4 footprint slots neatly alongside borders or into corners, while the high eaves and carefully designed ventilation support comfortable day-to-day use.

This freestanding greenhouse is glazed with 4mm twin-wall polycarbonate, offering improved insulation and impact resistance, making it supreme for gardeners who want a more resilient, temperature-stable growing environment. The low-threshold sliding door allows easy movement of trays, compost, and tools without intruding into the internal space. Supported by a reinforced aluminium frame, an optimised roof pitch, and the trusted ICON design, this greenhouse provides dependable performance in changeable UK weather. Whether positioned discreetly or as part of a larger garden layout, the ICON 6 Polycarbonate greenhouse delivers year-round practicality without dominating your outdoor space.

 

Frame and glazing options available

The Halls ICON 6 6x4 greenhouse is available in a choice of frame finishes and glazing types to suit different gardens and growing preferences. Beyond the green powder-coated frame, you can also choose from a powder-coated black aluminium or mill aluminium finish. While the mill aluminium is low maintenance, powder coating offers corrosion resistance to withstand inclement UK weather. Glazing options across the ICON 6 range include 3mm toughened safety glass, 3mm horticultural glass, and 4mm twin-wall polycarbonate.

What makes the ICON 6 Polycarbonate greenhouse easier to use

Impact-resistant polycarbonate glazing

The 4mm twin-wall polycarbonate panels are highly durable and do not shatter, making them an excellent choice for exposed locations, family gardens, or allotments. They also diffuse sunlight, helping to protect plants from harsh direct rays.

Improved insulation for steadier temperatures

Polycarbonate glazing offers better heat retention than standard glass, supporting more consistent growing conditions and extending the growing season earlier in spring and later into autumn.

Higher eaves for better comfort and airflow

The increased eaves height creates a more spacious internal feel and supports improved airflow, making routine tasks such as watering, potting, and plant care more comfortable.

Powder-coated aluminium for long-term protection

The green powder-coated finish adds an extra layer of protection against corrosion while maintaining a clean, attractive appearance with minimal maintenance.

Low threshold sliding door for everyday convenience

The sliding door preserves valuable internal growing space and allows smooth, obstruction-free access when carrying tools, trays, or compost.

Strong aluminium frame with minimal upkeep

The aluminium construction resists rust and weathering, removing the need for regular treatment associated with timber greenhouses.

Integrated guttering for rainwater collection

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

 

Optional add-ons to complete your greenhouse setup

The Halls ICON 6 Polycarbonate greenhouse can be tailored to suit your gardening needs from day one. Optional extras include a base plinth for added stability, a downpipe kit and waterbutt for rainwater collection, a louvre kit to improve airflow, traditional roof cresting to deter birds, and capping to enhance the finish and durability of the polycarbonate glazing system. Accessories must be purchased at the same time as your greenhouse.

 

Who the ICON 6 6x4 Polycarbonate greenhouse is best suited to

This greenhouse is ideal for gardeners who want a compact structure that remains comfortable, resilient, and easy to manage throughout the year. The polycarbonate glazing makes it particularly well suited to exposed gardens, family environments, and growers seeking improved insulation for seed propagation, herbs, vegetables, and overwintering plants. For higher production volumes or more defined growing zones, a 6x6, 6x8, or 6x10 greenhouse may be more appropriate. For most home gardeners looking for long-term value in a manageable footprint, the ICON 6 Polycarbonate offers a dependable and versatile solution.

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.
