I decided to build a concrete and Brick foundation and screwed the base to it and it looks well. To do this I had to cut the legs off flush with the base.
I found the instructions OK, i looked at the whole book before i started and did not have any issues with building the greenhouse itself, i had to loosen bolts is sections to get things lined up several times then nipped them all up once aligned – I used a cordless driver with a socket attachment which saved me loads of time i think.
The hardest parts were the window and the door to build. ! The standard bolts (top ones) are too long for the window to close fully as they bind against the frame so i shortened 2 bolts and it works perfectly… I need to look at the catch though as it is a bit cheap and not very good.
The diagram for the door is poor, i put the Poly in reversed so had to dismantle it to reverse it, for the UV effect ??
My biggest issue with the whole greenhouse is that there is approx a 1 cm gap either side of the door from top to bottom…. and i am sure it is built correctly…?? I need to fill the gap somehow
Overall i am really happy with this greenhouse

UPDATE Oct 2017
I have had this built for about 4 months now and the greenhouse looks OK but it is a total nightmare.
The Polycarb panes bend in the wind and come out of the guides at the sidesof each pane…you can either dismantle the whole roof to get them back in which takes a few hours, of flex them back in which creases them a little…
I am totally cheesed off with this greenhouse after 4 months, my next step is going to be to silicone round every pane…. if they still come out then it will be in the skip.
The nuts and bolts are very low grade stainless steel so they rust badly….i replaced the lot with aliminium
Only buy this if you live somewhere which gets zero wind… no where
I dread to think what it is going to look like after the winter

I’m generally pleased with this. It took me about 30 minutes to construct by myself (if you have a power screwdriver the job will be *much* easier, otherwise I recommend a drill to make additional guide holes). It’s not the best quality wood or paint job, but decent enough and the components fit together well. The magnetic closure on the doors is a welcome touch, and the roof opens and closes very effectively. It feels pretty spacious for a compact greenhouse and I’m confident it will do the job I want it to do.

I wood but it doesn’t state which wood, from the weight – or lack of it – I think it must be made from balsa! As for the paint I think this is where the phrase ‘a lick of paint’ comes from. I’ve had to paint mine as I can’t see it coming through 6 months of winter with the little paint that’s on it. Luckily I had half a tin of Little Greene exterior emulsion left over from my shed. I haven’t assembled it yet and hoping it will be easy but whilst painting it realised 2 of the dowels had got broken off in transit, found them in the packaging. Might put draught excluder around the doors as there are gaps which if it’s a hard winter will compromise the protection I think. I’m putting casters on mine so it will raise it off the floor and I can move it to catch the most sun through the winter. A nice looking little greenhouse although expensive for what it is.


  1. Does a polycarbonate greenhouse need to be secured to the ground?

Well, it’s actually yes. You never know when exactly can a natural calamity occur or may be a sudden gust of wind turn up your polycarbonate greenhouse and disperse it into several portions. Hence, you must always anchor or secure your greenhouse to the ground.

  1. Why should I buy a polycarbonate greenhouse?

Glasses are brittle and break much more easily as compared to other substances. And if you choose to buy a polycarbonate greenhouse, it has the chance to get broken or shattered quite often than you could expect. And on the contrary, polycarbonate greenhouses are shatter proof, damage proof to natural disasters and also does not break easily. So, you must always choose to buy a polycarbonate greenhouse over the outdated glass made ones.
