Halls ICON 6 6x12 Planthouse 3mm Toughened Glass - Black HR01223

Discover a spacious, comfortable and freeing growing environment with the Halls ICON 6 6x12 planthouse

Designed for gardeners who want more freedom to grow and work comfortably, the Halls ICON Planthouse 6 6x12 offers a generous footprint and noticeably increased height without dominating the garden. The extended 6x12 layout provides space to move, organise staging, and grow taller crops with ease, while the planthouse design creates a calmer, more open internal feel than a traditional greenhouse. It delivers the practicality of a large growing structure while remaining visually balanced and easy to live with year-round.

With its broad proportions and enhanced headroom, this planthouse suits gardeners who want a greenhouse growing space that feels usable rather than restrictive. Whether tending climbing vegetables, arranging shelving, or potting up plants, the extra height and width make everyday tasks simpler and more enjoyable across the seasons.

 

Strong construction with practical features for everyday use

Built around a robust aluminium frame finished in powder-coated black, the Halls ICON Planthouse 6 6x12 combines durability with a modern, understated appearance. The structure is glazed with 3mm toughened safety glass, providing excellent light transmission alongside increased strength and peace of mind, particularly in family gardens or more exposed locations.

A wide double sliding door positioned on the long side, paired with a low threshold, allows easy access for trays, compost bags, tools, and larger planters while maintaining valuable internal growing space. Four roof vents support effective ventilation, helping to regulate temperature and humidity during warmer months. Designed for gardeners who plan to spend time inside their greenhouse, this model prioritises comfort, airflow, and reliable performance in typical UK conditions.

 

Frame colour and glazing options available

The Halls ICON Planthouse range is available in powder-coated green or powder-coated black, allowing you to choose a finish that best suits your garden style and surroundings. Both frame options are applied to a durable aluminium structure, offering excellent resistance to corrosion and requiring minimal ongoing maintenance.

The green frame is a popular choice for traditional gardens, blending naturally into planting schemes, lawns, and surrounding foliage. It creates a softer, more understated presence and is often preferred by gardeners who want their planthouse to sit quietly within the landscape rather than stand out. The black frame offers a more contemporary look, providing clean contrast against planting and paving. It suits modern garden designs and structured layouts, giving the planthouse a sharper, architectural appearance while still remaining practical and easy to maintain.

Glazing options allow gardeners to choose the right balance of appearance and durability. 3mm toughened safety glass offers increased strength and reassurance, making it a practical choice for family gardens, frequent use, or more exposed locations. This planthouse is supplied with 3mm toughened glass, combining clarity with added durability for everyday growing.

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.
