Halls ICON 6 6x8 Greenhouse 4mm Polycarbonate - Black HR01092

For gardeners wanting more room without overwhelming their garden, the Halls ICON 6 6×8 Greenhouse provides a spacious, balanced growing space that feels easier to use and more functional than smaller greenhouses.

Make the most of your outdoor space with this thoughtfully sized greenhouse. The extended 6x8 footprint offers generous room for staging shelving, larger pots, and better internal organisation without dominating your garden layout. Designed as a freestanding structure, it allows more flexibility in placement while delivering improved airflow, higher eaves, and a calm internal environment for watering, potting, and everyday plant care, ensuring you feel the benefits of a larger greenhouse while still fitting well in most gardens.

Built with a durable powder-coated black aluminium frame, insulating 4mm twin‑wall polycarbonate glass panels, and an optimised roof design, this ICON 6 6×8 greenhouse balances practicality with performance. Installed with a low‑threshold sliding door that allows smooth movement of trays, compost, and tools while preserving the full internal growing area. Whether you’re expanding your growing ambitions or want more space to work comfortably, this model delivers reliable performance and ease of use through every season.

Frame colour and glazing options available

This Halls ICON 6 6×8 is available in a sleek black powder‑coated frame, offering a modern, low‑maintenance finish that resists corrosion and blends seamlessly into a variety of garden styles. For gardeners seeking a different look or performance, alternative frame and glazing options are also available.

A traditional green powder‑coated frame provides a classic, natural appearance that complements garden settings, while mill aluminium frames offer a neutral, contemporary aesthetic and require minimal upkeep. When it comes to glazing, 3 mm horticultural glass delivers clear light transmission, ideal for promoting healthy growth of vegetables, herbs, and tender plants. For added strength and peace of mind, 3 mm toughened safety glass offers impact resistance without compromising light levels. Meanwhile, 4 mm twin-wall polycarbonate panels improve insulation, retain warmth, and provide extra protection for more delicate plants, making them perfect for year-round gardening. These options allow you to tailor the greenhouse to your priorities, whether that’s maximising light, enhancing durability, or improving temperature stability.

What makes the ICON 6 6×8 easier and safer to use day to day

Polycarbonate glazing for insulation and durability

The 4mm twin-wall polycarbonate panels provide excellent insulation and durability, helping maintain stable internal temperatures while protecting plants from impact and harsh UK weather.

Extended footprint for more space and organisation

With the larger 6×8 size, there’s more room to move around, fewer bottlenecks, and better internal flow — perfect when tending multiple trays, arranging 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 40mm 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, a downpipe kit and  waterbutt and stand for rainwater harvesting, a louvre kit for extra airflow control, capping for improved durability, or cresting for a finished look. Optional folding modular staging and shelves also sit neatly inside the 6x6, 6x8, and 6x10 models for flexible, space‑saving plant storage.

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

 

Who the ICON 6 6×8 greenhouse is best suited to

The ICON 6 6×8 is designed for gardeners who want more room to grow and work comfortably without stepping up to a very large structure. It’s excellent for seed propagation, vegetables, herbs, larger pots, and overwintering plants, providing a controlled environment that feels spacious yet manageable, the extra length makes daily use feel more practical, especially if you’re moving up from a 6×4 or 6×6 greenhouse.

For many home gardeners seeking extra growing 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.
