  Best Review From Customers

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.

Worst Customer Review

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.
