Rated 1 out of 5 by from Poor quality and the instructions are useless Poor workmanship and finish to the product. Although advised you will need a saw it is impossible to find the right part you need as the they are not marked and oversized to the instruction dimensions. For the cost not value for money

Rated 1 out of 5 by from Mercia 6 X 6 greenhouse I paid £399 30 days before the item was delivered. What I did not know was the kit cannot be assembled straight away. It came with a pack of building site off-cuts (Mercia information) that has to be prepared using a Router for chamfering and cut to length. It was a bad experience when I thought I only have to assemble the greenhouse; so be prepared to do massive joinery/carpentry.

Rated 2 out of 5 by from Could be better The advert picture above looks great however in reality it is far from the one that I got and really tested my abilities because of the poor instructions supplied This could be a very good product if more care given to quality control and finishing during the manufacturer of this product with better care and quality control - the one that I received had nails sticking through one panel and miss-aligned panels that had been nailed together. Mercia customer services told me that the wood supplied with this product is generic, which meant that I had to cut the all to size, (you don’t expect a piece of flat pack furniture only to be told to cut to the wood to size). ..............Not Recommended.................

Rated 2 out of 5 by from Not great This looked like a great purchase however it has really tested my abilities. The installation manual was very unclear with less than clear and incomplete timber size information. Following this it was discovered that the timber and fixing pack was a missing some integral lengths of timber yet had far to many lengths of other pieces that would not fit where the missing pieces should go. I had to take a trip to my local builders merchant to get extra lengths of timber at my own expense. The general construction of the panels is also quite poor and the fit is less than ideal. The door was also to wide and need a lot of work to get it to fit. This was caused by poorly fitted tongue and groove boards and bowed and twisted timber on the frame. On the upside when built it is not a bad little green house and fits nicely into my garden. There is plenty of head room for me, (I'm 6' 4"). I would say overall this a fair to middling construction which for the cost is poor as I could have bought the same size aluminium framed greenhouse for less.

Rated 3 out of 5 by from With more care this could be a good product Not enough quality control before delivery. Single nails used in roof frame construction Leading to twisting Distorted plastic channelling due to poor packaging Uncut trims and channelling Significantly increasing build time and knowledge required due to poor instructions This could be a very good product if more care given to quality control and finishing.

Rated 1 out of 5 by from Very dissapointed We have just taken delivery of the 6x4 version of this. Several pieces are damaged and pieces missing. We have waited 6 weeks for this to arrive (understandably in the current climate). It's now probably going to take another 6 weeks to have it collected and taken away. Very dissapointed.
