Frame colour options and glazing choices

The Halls ICON 8 8x12 Greenhouse comes in three premium aluminium frame finishes to suit your garden style. The green powder-coated frame offers a natural, classic look that complements foliage, while the powder-coated black finish delivers a sleek, contemporary style. The mill aluminium frame provides a neutral, modern aesthetic that highlights the greenhouse’s refined design.

Glazing choices include 3mm horticultural glass, providing excellent clarity and light for vigorous plant growth at a practical price, and 3mm toughened glass for added safety and strength, shattering into small blunt fragments if broken.

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.
