Halls ICON 6 6x12 Planthouse 3mm Toughened Glass - Green HR01224

Create a spacious, comfortable growing environment designed around how you garden with the Halls ICON Planthouse 6 6x12

With its generous 6x12 footprint and noticeably higher eaves, the ICON Planthouse 6 6x12 provides a growing space that feels open, calm, and practical to use every day. Unlike traditional greenhouses that prioritise compact layouts, this planthouse gives you the freedom to move, work, and grow taller plants comfortably without the sense of restriction that smaller or lower-profile models can create. The extended length and vertical walls offer a balanced structure that fits confidently into established gardens while delivering the benefits of a truly usable internal space.

Designed for gardeners who value comfort as much as growing capacity, the planthouse layout improves airflow, headroom, and organisation. Whether you’re tending climbing vegetables, arranging shelving, or moving tools and pots in and out, the proportions of this model make everyday tasks feel easier and more enjoyable, supporting productive gardening throughout the seasons without overwhelming your outdoor space.

 

Built for height, access, and long-term use

This Halls ICON Planthouse 6 6x12 features a strong powder-coated green aluminium frame paired with 3mm toughened safety glass, offering a durable, reassuring structure suited to UK weather conditions. The extra-high eaves and tall ridge height create valuable vertical growing room, allowing plants to develop naturally while giving you the ability to work upright across the full width of the planthouse.

A wide double sliding door positioned on the long side, combined with a low threshold, ensures smooth access for wheelbarrows, compost bags, trays, and larger planters. Four roof vents promote effective ventilation, helping regulate temperature and humidity during warmer periods and creating a healthier environment for plants. This thoughtful combination of height, access, and ventilation makes the planthouse particularly well suited to gardeners planning ambitious layouts or upgrading from a more restrictive greenhouse.

 

Frame finish and glazing choice

The ICON Planthouse 6 6x12 is available with a choice of powder-coated green or powder-coated black aluminium frame, allowing you to match the structure to your garden style and surroundings. Both finishes provide excellent corrosion resistance and long-term protection, ensuring the frame remains durable and low maintenance over years of use. The green frame offers a traditional, garden-friendly appearance that blends naturally with planting schemes and established outdoor spaces, making it a popular choice for classic gardens and softer landscapes. The black frame delivers a more contemporary, architectural look, creating strong contrast against planting and paving and suiting modern garden designs where clean lines and structure are preferred.

Both frame options are paired with 3mm toughened safety glass, selected for its strength, clarity, and reassurance in everyday use. Toughened glass provides excellent light transmission while offering increased impact resistance compared to standard horticultural glazing, making it well suited to family gardens, exposed locations, and long-term installations without compromising the traditional greenhouse aesthetic.

What makes the ICON Planthouse easier and more enjoyable to use day to day

Extra height for comfort and flexibility

The increased eaves and ridge height allow you to stand upright throughout the space, making watering, potting, and plant care more comfortable while supporting taller crops and climbing plants.

Wide access for practical gardening

The long-side double sliding door and low threshold make everyday access easier, especially when moving bulky items or working regularly inside the structure.

Toughened glass for confidence and longevity

3mm toughened glazing offers improved impact resistance and safety, delivering a reassuring, long-lasting solution without compromising light levels.

Improved airflow for healthier growing

Four roof vents help maintain balanced ventilation, reducing excess heat and humidity during warmer months.

A layout designed around the gardener

The planthouse format prioritises movement, organisation, and usability, creating a calmer working environment compared to more compact greenhouse designs.

 

Optional additions to complete your setup

The ICON Planthouse 6 6x12 can be enhanced with compatible accessories at the point of purchase. A galvanised steel base plinth is strongly recommended to provide a stable, level foundation and maximise long-term durability. Optional additions may also include roof vent automation, gutter downpipes for rainwater collection, capping for added glass security, and internal staging or shelving to suit your growing plans.

Optional accessories must be ordered at the same time as the planthouse.

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.
