Select Your Options
Option 1 > Greenhouse Glass
Three types of glazing are available for your greenhouse. Choose from standard horticultural, long pane toughened or 6mm polycarbonate options which let you customise your greenhouse to suit your needs.
Glass diagram images below are for demonstration of the glazing styles and may differ depending on your chosen greenhouse model.
Option 2 > Base Plinth?
All greenhouses need to be fitted onto a secure base. This can be achieved by using an official Halls branded metal base plinth to give the greenhouse added strength and height. Alternatively you can build a brick base to fit your greenhouse size if you prefer.
Please Note: If you're having your greenhouse installed by the Halls team, you will need to purchase this base along with your greenhouse.

Ventilation is essential for any Greenhouse no matter the size to ensure that the humidity and temperature inside provides the best growing experience for your new plants.

Great Value for Money
Searched the internet for best buy and best quality, read reviews and decided on this greenhouse. Customer service is very good and delivery driver very helpful and rang before delivery. Quality of greenhouse is great, very sturdy with spacious headroom. Took ages to erect though. Majority of items were clearly labelled but not all, and some were hard to identify. The instructions are rubbish, put it together and took apart lots of times as put some parts on the wrong way round or missed out screws because diagrams/instructions weren't clear or non existent. Hooray for the internet, found a couple of websites that helped and youtube. Overall very happy with greenhouse and would recommend it.

As good as expected
Liked the look of this greenhouse, not least the price which I thought very competitive. The extras are well worth considering, the louvre is good at increasing air circulation and I've found the staging essential. Glad I bought this one.

Lots of Working Area
This Halls greenhouse gives you lots of working area for your money and that's why I bought it. The double doors make access in and out of the greenhouse so much easier - I don't think I would recommend a single door greenhouse now I've got double doors. I also ordered some staging and an automatic vent which means one of the windows opens and closes itself as the temperature rises and falls again. Make sure you sue gloves when putting it up, especially with the glass, which is obvious really. The basic frame is very simple to install, the most difficult thing is identifying which piece is which, but a lot of them are the same to be fair. Looks good when finished and with some plants inside.
