I was a little hesitant to order this because a lot of the reviews talked about the difficulty of putting it together, lack of detailed instructions, etc. I was also hesitant because typically, DIY structures don't always fit together correctly, there are missing pieces, and so on. I was wrong. This arrived two days earlier than the expected delivery date, which was the first positive. It's starting to get cold here so the sooner the better! After reading several reviews, I decided to follow some of the suggestions and inventory all the pieces upon arrival to prevent frustration down the road. Everything arrived in perfect condition (a few of the panels has bent corners, but nothing that affected the quality of the structure). Again, follow previous reviewers instructions, I laid all the pieces our, label up, for easy identification when putting it together. Now, the instructions COULD use some more details, however, if you just pay attention to the illustrations and notes, it's not too bad. There were a few steps that stumped me, but after playing around with the pieces fitting together, I was able to figure it all out. They recommend 2 days and 2 adults to build this, but I built it in a day and a half by myself. 38 yo male, 5'9, with minimal issues. There is not any part that couldn't be done alone, but if you have two people, it would obviously go quicker. Typically, I have issues at some point with holes not lining up, pieces not fitting together properly, and so on. I had ZERO issues with this kit. Every single hole lined up perfectly, every part went together as it should, there were no alignment issues with the structure itself, and it looks fantastic. I could not be more pleased with this kit. As I stated, I was hesitant, but wow. I would recommend it to anyone that has the space and ability to DIY. Would definitely buy again from this brand. I'm so impressed.

Overall this is pretty good. It's a fairly clean/simple design, and seems solid (time will tell). It took a bit over a full day of work to assemble, and you really want 2 people for some steps. The instructions are mostly ok, for having been written by non-English speakers. The parts are well labeled, and the diagrams are pretty good. But they often leave out critical details about which way a part goes -- flange to the inside or outside, this end up or down. Usually they only work one way, but you can only figure that out much later. We ended up having to take parts back out multiple times. In a couple places the instructions are clear on this -- mostly not. Several parts were slightly crushed or bent and had to be straightened. Nothing really broken, just a pain. Parts are accurate, so the holes line up right. The "posts" they promise to "help bury the greenhouse deep in soil or concrete for extra stability" are little sheet metal brackets about 6" long. I don't think they'd do much of anything unless they're embedded in concrete. Put this on a solid base of some kind, with real anchors. I used 6x6s and a few 24" ground anchors. In several cases you need to pre-load bolts into T-slots before assembling, to use later. In a couple cases the instructions say so but in many they don't. So that means more disassembly if you don't read and think far ahead. They could easily have provided T-track bolts for those instead. One big pain was the hardware -- it was short several nuts and bolts (even counting the pack of "spare parts"). But the really weird thing is, the nuts and bolts have metric threads (M6) but English heads (3/8"). We had to buy a bunch of metric hardware, but that means the last several bolts want different wrenches (10mm). You probably have the right tools, but having to choose between matching all the threads and matching all the heads is just weird, and will be a pain again any time a nut works loose. So it seems pretty nice once done, but expect a lot of fiddling and frustration in the process.

This is my first greenhouse so I have nothing to compare to but overall I think this is going to work just fine but I might have something more to say after winter. I am in NH gardening zone 5b and we can get a foot or more in any one snow storm. But it really seems pretty solid so I am optimistic. Assembly went pretty well as long as I read the directions! I had to go back and disassemble and reassemble a few things but that’s on me. I dug out an 8 x 10 foot area and put down cinder blocks for a foundation followed by double 2x6s all around and then built on top of this. The only assembly suggestion I have is to fit the doors to the frame as early as possible. My doors bind a little and I probably could have dealt with it if I did an early fit-up. Probably have to resort to some filing now. I used silicon calking and the roof does not leak except just a bit around the windows. On a windy day one of the windows completely flew off the roof. No damage. I put it back and hung a weight to slow down the reaction to wind (2ft long 2x4). Parts were all well marked and the assembly instructions had been updated with some correction tape. I really don’t have any complaints.

Excellent greenhouse. Had it now just over a year. I added the automatic roof vent openers to keep the temperature in the summer in South Carolina under control. Very sturdy construction. I have mine on a railroad tie foundation. I added a rain barrel outside to catch the water from the gutter system it comes with. Very pleased with the greenhouse. My only advice is to read the instructions several times over and watch the video on how pieces go together. It takes longer to put together than advertised.
