Hassle-free gardening with our Pressure Treated Greenhouse. We apply the treatment in a pressurised tank so that you don't have to! Your greenhouse will remain free from rot and fungal decay for longer than with competitors' dip treatment. Our greenhouse glass is 4mm toughened glass which is more resistant to damage than horticultural glass or Perspex. We give you staging as standard and a WPC panel which is ideal for hanging tools, coats and equipment. Also included is our auto-opening window, which reacts to the outside temperature so that you don't have to. 

Product Features
Greenhouses Pressure Treated Timber
Pressure treated
All of the slow grown spruce in our Greenhouse has been cut to size, planed and then pressure treated for an equal, complete coverage rather than leaving exposed edges which renders the protection useless. The pressure treatment process forces Tanalith E deep within the timber, protecting it against rot and fungal decay without the need to retreat it. This is a vital aspect of your Greenhouse as it will face a variety of elements throughout the year, all of which can cause weaknesses and structural problems if the Greenhouse is left to rot. Our treatment ensures a robust, strong and sturdy Greenhouse for you to work in.
Greenhouses Toughened 4m Glass
Greenhouses Toughened 4m Glass II
Toughened Glass
4mm toughened glass is far stronger than the 3mm horticultural glass, 4mm float glass, styrene or Perspex that many of our competitors offer. In fact, we tested it against three of the four above, by hitting them with bricks and rubbing them with a supermarket brillo pad – our 4mm toughened glass remained clean, clear and in one piece. This means you won’t have to go through the hassle, and expense, of replacing the glass should it get hit by a stray football or brick. On the rare occasion your toughened glass does break, it will crumble safely rather than break into dangerously sharp shards. 
Greenhouses Staging Included
Staging included
To help you in growing plants and crops of all kinds, we include staging as standard. The staging is attached to the framework, ensuring there are no legs or stands in your way which might be a hazard. The fixed staging will help you organise all your pots, plants and tools just how you want them. We use pressure treated timber which ensures it is protected from rot and insect infestation for at least 10 years without the need for you to annually treat it.
Greenhouses Auto-Opener As Standard
Auto-opener Included
Our Greenhouse comes with an automatic opening, temperature sensitive skylight that allows your plants to be adequately ventilated all year round. The opener will automatically adjust to ensure your plants get the correct amount of air whilst offering protection from the outdoor elements if the weather decides to take a turn for the worse. It is a much more convenient option then manually adjusted openers, and there is no risk of forgetting!
Greenhouses Wood Plastic Composite Panel 1.8m Wide
The Greenhouse features a wood plastic composite panel (WPC) on the back wall. The strong, durable material is not only extremely resistant to excessive temperatures but requires very little maintenance to maintain its high-quality finish. The hard-wearing material does not corrode and is highly resistant to rot and fungal decay, much like our pressure treated timber. The thick panel is perfect for additional storage – you could hang hooks that allow you to easily hang tools, coats and array of equipment. It’s all up to you!
Greenhouses Avoid Planning Permission 1.8 x 1.2
Greenhouses Avoid Planning Permission 1.8 x 1.2 II
Avoid Planning Permission
This building is under 2.5m high.
Why does this matter? Well, under permitted development rights buildings under 2.5m high can be placed as close as you want to a boundary (eg. a fence line) without planning permission. Buildings that are over 2.5m high, however, need to be placed over 2m away from any boundary (eg. a fence line), which means that with taller buildings you end up with a lot of space behind them. If you want to find out more about permitted development rights see our planning guide


How high is this Greenhouse?
It is 2.08m (6' 9") high
What type of glass do you use in this Greenhouse?
We only use 4mm toughened glass in our Greenhouses which is a far more hard-wearing and resilient material than commonly used Perspex and styrene.
Do you offer any guarantees or warranties on this product?
We offer a genuine 10-year guarantee against rot and insect infestation on our pressure treated timber.
Do you have to paint or treat this Greenhouse?
This Greenhouse is pressure treated so will not need to be painted or treated for up to 10 years. However, you may wish to treat with water repellant for timber maintenance.
What timber is this Greenhouse made from?
We use slow-grown Spruce timber for the main structure of the Greenhouse. Spruce is less porous than Pine and so less likely to shrink, warp or split.
