Halls ICON 6 6×4 Greenhouse Horticultural Glass - Black HR01008

The Halls ICON 6 6×4 Black greenhouse offers compact, robust growing space with 3mm horticultural glass—perfect for small UK gardens.

Designed for gardens where space is limited, the ICON 6 6x4 greenhouse provides a practical growing room without feeling oversized. Its compact footprint makes it perfect for smaller gardens while still suiting larger outdoor areas where proportion and layout matter. Designed to fit neatly in corners or along flowerbeds, it provides high eaves and improved airflow for comfortable watering, potting, and everyday plant care—delivering the usability of a full-size greenhouse without dominating your garden.

Built with a reinforced aluminium frame, 3mm horticultural glass, and an optimised roof pitch, the ICON 6 combines durability with a practical, space-saving design. A low-threshold sliding door allows easy movement of trays, compost, and tools while preserving internal growing space. Whether you’re short on room or simply want a discreet, reliable 6x4 greenhouse that doesn't compromise the flexibility of your outdoor space, the ICON 6 provides dependable performance in a compact, low-maintenance structure.

 

Frame colour and glazing options available

The Halls ICON 6 6x4 greenhouse range is designed to suit different garden styles, budgets, and growing priorities. Alongside this black powder-coated aluminium version, the ICON 6 is also available with a classic powder-coated green frame or a clean, low-maintenance mill aluminium finish, allowing you to tailor the appearance that fits naturally within your garden.

Glazing options vary across the range to support different growing needs. Traditional 3mm horticultural glass offers excellent light transmission and a familiar greenhouse look, making it a popular choice for everyday growing. For added strength and peace of mind, 3mm toughened safety glass is available on selected models, breaking into small blunt pieces if damaged. Gardeners looking for improved insulation and reduced heat loss may prefer 4mm twin-wall polycarbonate, which also offers greater impact resistance.

This flexibility across frame finishes and glazing types means the ICON 6 6x4 can be customised to suit first-time greenhouse buyers and more experienced gardeners looking for a specific balance of appearance, durability, and performance.

Why the ICON 6 is easier and safer to use daily

Horticultural glass for reliable plant growth

The 3mm panels allow excellent light transmission and traditional greenhouse appearance while remaining strong enough for regular UK weather conditions.

Higher eaves for comfort and airflow

Generous internal height and ventilation improve air circulation and make watering, potting, and moving plants more comfortable.

Durable black finish for long-lasting protection

The powder-coated aluminium frame resists corrosion and maintains a sleek appearance with minimal maintenance.

Low-threshold sliding door for smooth access

Eases the movement of trays, compost, and tools without compromising internal space.

Stable aluminium frame with reduced upkeep

Offers long-term performance without the maintenance demands of timber structures.

Secure glazing system reduces condensation  

The G-clip system and integrated glass stops hold panels securely and manage condensation, keeping the interior cleaner and more functional.

Integrated gutters for rainwater management

Wide gutters can be connected to optional 40mm downpipes for easy water collection.

 

Get more from your ICON greenhouse with optional add-ons

Enhance your setup with practical add-ons such as a waterbutt and stand for efficient rainwater collection, a downpipe kit to direct water flow, a louvre vent kit to improve airflow during warmer months, and traditional cresting can be added for a classic greenhouse finish. These optional extras allow you to create a more complete, tailored greenhouse setup from the outset, ensuring everything works together smoothly from day one. All add-ons must be purchased at the same time as your greenhouse for coordinated delivery and installation.

 

Who the ICON 6 6x4 greenhouse suits

Ideal for gardeners seeking a compact, dependable greenhouse for seed propagation, herbs, seasonal crops, and overwintering plants. It provides a controlled growing environment without the cost or visual impact of larger structures. For higher production or clearly defined growing zones, larger models like the 6x6, 6x8, 6x10 may be better suited, but for most UK home gardeners, the ICON 6 represents a practical, long-term investment.

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.
