Strong, dependable construction for everyday gardening

Crafted for durability and longevity, the Halls ICON 8 8x12 Greenhouse features a high-quality aluminium frame with a sleek black powder-coated finish. This corrosion-resistant design ensures enduring performance with minimal upkeep, even under the toughest UK weather conditions. Its modern black frame adds a premium touch while offering excellent protection against wear.

Glazed with 3mm horticultural glass, the greenhouse provides superior light transmission to promote healthy growth while maintaining a safe and secure environment. Long, continuous glass panels enhance the stylish appearance and contribute to structural strength.

A smooth-sliding door with a low threshold ensures effortless access for tools, trays, and wheelbarrows. Manual roof vents support optimal airflow and temperature control, helping maintain ideal growing conditions all year round.

 

Frame colour options and glazing choices

The Halls ICON 8 8x12 Greenhouse comes in three premium aluminium frame finishes, allowing you to match the style to your garden. The green powder-coated frame blends naturally with foliage, creating a classic garden look. The black frame provides a bold, modern aesthetic, while the mill aluminium frame delivers a clean, neutral appearance suited to any garden style.

Two glazing options are available to suit your needs. 3mm horticultural glass offers excellent clarity and light transmission, promoting strong plant growth with a cost-effective solution. 3mm toughened glass provides extra strength and safety, shattering into small, blunt fragments if broken, ideal for family-friendly gardens. Both options ensure consistent performance and optimal growing conditions year-round.

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.
