Product Description
Finished in anthracite and thoughtfully specified for year-round use, this Halls Signature Grand greenhouse combines generous capacity, low-maintenance materials and considered detailing to create a reliable environment for serious cultivation and extended growing seasons. Built on a powder coated aluminium frame, the structure resists rust and corrosion and includes wind braces and reinforcement bars for dependable structural integrity across the long span.
Toughened 3mm safety glass is fitted throughout to deliver excellent light transmission for seedlings, container plants and larger potting projects. All fixings including glazing clips and screws are stainless steel to reduce corrosion and keep the frame looking smart. A wide set of double sliding doors across the 8 ft front gives effortless access for benches, wheelbarrows and planting, while multiple roof vents help you control ventilation and temperature.
Practical accessories supplied as standard include a sturdy base plinth for secure siting with soft-ground spikes or the option to bolt down to hard ground, plus a twin downpipe kit to divert rainwater neatly away from the frame. The package is backed by a 10 year frame guarantee and is available with stepped accessory options so you can add staging, shelving and extras to suit your needs.

The delivery cost can differ depending on your location as well as your chosen greenhouse size and model, and so any delivery charge can be found under the “Delivery Services” options above. The delivery charge will be added to your total order price within the basket. The delivery timeframe may vary for each greenhouses range and so an estimated delivery timeframe can be found on each product page, giving you the most up-to-date and realistic delivery information.
You may be wondering why we have to charge surcharges to deliver to some areas - unfortunately this is down to the delivery carrier providers and something that is out of our hands. Greenhouses are large, heavy and require a specialty delivery service to ensure that the frame and delicate fragile glass reach our customers in perfect condition. Due to the nature of them being bulky, heavy freight and with abnormal sizing compared to a standard boxed parcel, delivery providers supplement the delivery with additional consignment charges.
