Halls ICON 6 6x8 Greenhouse 3mm Horticultural Glass - Black HR01090

Too small to work in comfortably, but not wanting something that overwhelms your garden? The Halls Icon 6 6x8 Greenhouse brings balance between space and proportion.

Make the most of your outdoor space with this roomier greenhouse. Its extended 6x8 footprint gives you more room to organise plants, staging, and access points without dominating your garden layout. Designed to sit neatly where you want it, this freestanding structure offers improved airflow, higher eaves, and a calmer internal environment for watering, potting, and everyday plant care, giving you the usability of a generously sized greenhouse without feeling too large for most family gardens.

Built with a durable aluminium frame, expert horticultural glass, and an optimised roof design, the ICON 6 6×8 combines practical performance with thoughtful proportions. A low-threshold sliding door allows easy movement of trays, compost, and tools while preserving the full internal growing area. Whether you’re expanding from a smaller greenhouse or starting with greater growing intentions, this model provides reliable performance and a comfortable working space throughout the seasons.

 

Frame colour and glazing options available

Frame finishes include powder-coated black and powder-coated green[LINK], both offering a durable, corrosion-resistant surface that helps protect the aluminium frame from everyday wear while giving a more refined, long-lasting appearance. The black finish suits modern or contemporary gardens, while the green frame blends naturally into traditional planting schemes. A mill aluminium frame[LINK] is also available for those who prefer a clean, low-maintenance finish that stays neutral and understated over time.

Glazing options can be selected based on your priorities around light, safety, and insulation. 3mm horticultural glass provides excellent light transmission and a traditional greenhouse feel, making it a popular choice for seed sowing, vegetables, and general growing. 3mm toughened safety glass[LINK] offers increased strength and peace of mind, breaking into small, blunt pieces if damaged and making it a sensible option for family gardens or more exposed locations. For gardeners focused on insulation and durability, 4mm twin-wall polycarbonate[LINK] glazing helps retain warmth, reduces heat loss, and stands up well to harsher weather conditions.

What makes the ICON 6 6x8 easier and safer to use day to day

3 mm horticultural glass for healthy plant growth

The 3 mm horticultural glass provides strong, natural light that helps seedlings, vegetables, and tender plants thrive, while maintaining the traditional greenhouse look and feel.

Extended footprint for more space and organisation

With the larger 6x8 size, there’s more room to move around, fewer bottlenecks, and better internal flow — ideal when tending multiple trays, rearranging staging, or working with taller plants.

Powder-coated aluminium frame for lasting protection

The black powder-coated aluminium frame resists corrosion, fading, and general wear, helping your greenhouse stay strong and looking smart with minimal maintenance.

Higher eaves for improved comfort and airflow

Increased internal height creates a more open feel, enhances ventilation, and makes everyday tasks such as watering, potting, and plant care more comfortable.

Low-threshold sliding door for easy access

The smooth-glide sliding door preserves internal space while making it simple to move trays, tools, and compost in and out safely.

Stable roof and structure for dependable performance

The reinforced aluminium frame and optimised roof pitch ensure the greenhouse performs reliably in a variety of UK weather conditions, giving peace of mind year-round.

Integrated guttering for controlled rainwater collection

Wide gutters are ready for connection to optional 40 mm downpipes, making it straightforward to harvest rainwater for a more sustainable growing setup.

 

Optional add-ons to create a complete setup from the get-go

The Halls ICON 6 6×8 greenhouse can be enhanced with optional accessories at the point of purchase to create a complete growing setup. Add a galvanised steel base plinth for secure anchoring, downpipe kit and waterbutt and stand for rainwater harvesting, louvre kit for extra airflow control, capping for improved durability, or cresting for a finished look. Optional folding modular staging and shelves that fit neatly into the 6x6, 6x8, and 6x10 greenhouses for flexible, space-saving storage for plants, trays, and gardening tools. These options allow you to tailor the structure to your gardening style. 

Additions can only be purchased at the same time as ordering your greenhouse.

 

Who the ICON 6 6x8 greenhouse is best suited to

The ICON 6 6×8 is designed for gardeners who want more space to grow comfortably without stepping up to a very large structure. It’s well suited to seed propagation, growing vegetables and herbs, organising larger pots, and providing a controlled environment for overwintering plants. The extra length makes daily use feel more practical and relaxed, especially if you’re moving up from a 6x4 or 6x6 greenhouse.

For many home gardeners seeking more internal space with dependable performance and a clean garden-friendly footprint, the ICON 6 6×8 offers a practical and reassuring choice.

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.
