Strong, dependable construction for everyday gardening

Built for durability and consistent performance, the Halls ICON 8 8x12 Greenhouse features a robust aluminium frame with a clean, mill-finished surface. This corrosion-resistant construction is designed to withstand the demands of the UK climate while requiring minimal ongoing maintenance. The natural aluminium finish offers a timeless, understated appearance that complements any garden style.

Fitted with 3mm horticultural glass, the greenhouse delivers excellent light diffusion, helping to protect plants from scorching while promoting even growth. The overlapping glazing panels are securely fixed to maintain stability and reliable weather resistance, making horticultural glass a trusted choice for traditional greenhouse growing.

A smooth-sliding door with a low threshold ensures easy access when carrying pots, trays, or tools. Manual roof vents encourage effective air circulation and temperature control, helping to maintain optimal growing conditions throughout the year.

 

Frame colour options and glazing choices

This model of the Halls ICON 8 8x12 Greenhouse is supplied with a mill-finished aluminium frame, offering a clean, neutral appearance that complements both traditional and modern garden settings. For those seeking a different aesthetic, the ICON 8 range is also available with green powder-coated frame, ideal for blending naturally into planting areas, or black powder-coated frame for a bold, contemporary look with added visual impact. All frame finishes are manufactured from high-quality aluminium, providing excellent corrosion resistance and long-term durability.

The greenhouse is glazed with 3mm horticultural glass, a popular choice that delivers excellent light transmission while softly diffusing sunlight to support healthy plant growth. Alternatively, 3mm toughened glass is also available across the range, offering increased strength and enhanced safety through its safe-break characteristics. Both glazing options are securely fitted using Halls’ proven fixing system to ensure reliable performance and stability throughout the year.

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.
