What makes the ICON 6 easier and safer to use daily

Twin-wall polycarbonate panels for insulation and light diffusion

The 4mm twin-wall polycarbonate panels provide excellent light diffusion, improve insulation, and offer strong impact resistance to create a reliable growing environment for your plants.

Higher eaves for better comfort and airflow

Increased eaves height creates a more open internal space, improves airflow, and makes everyday tasks such as watering, potting, and plant care more comfortable in the compact 6x4 greenhouse.

Mill aluminium frame for durability and low maintenance

The Mill aluminium frame resists corrosion, requires minimal maintenance, and ensures long-term strength and reliability throughout many seasons.

Low-threshold sliding door for easier access

The smooth-sliding door preserves internal growing space and allows effortless movement when carrying trays, compost, or gardening tools.

Stable aluminium structure for dependable use

The reinforced aluminium structure supports long-term performance and withstands changing weather conditions without the ongoing upkeep required for timber frames.

Secure G-clip glazing system with integrated stops

The G-clip system holds panels firmly in place, reduces vibration in exposed conditions, and diverts condensation to keep the interior cleaner and quieter.

Integral guttering for efficient rainwater collection

Integral gutters run along the eaves and can be connected to an optional 40mm downpipe kit, allowing straightforward rainwater harvesting.

 

Optional add-ons to create a complete setup

Enhance your greenhouse with optional extras including a water butt and stand, downpipe kit, louvre vent, decorative cresting, and protective capping. All accessories must be purchased with your greenhouse and allow you to customise functionality, durability, and style.

 

Who the ICON 6 6x4 greenhouse suits

Designed for gardeners seeking a compact, practical greenhouse, the ICON 6 suits seed propagation, herbs, seasonal crops, and overwintering plants. For larger-scale production or clearly defined growing zones, bigger models may be preferable. For most home gardeners, the ICON 6 delivers long-term value in a modest, efficient footprint.

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.
