I ordered the 8x12 and it arrived in 4 boxes - one for the front 2 foot section, one for the back 2 foot section and 2 for the middle 4 foot section. Be warned: there are close to 1,000 pieces in these boxes. But don't be put off by that, most of them are very small connectors to hold the joints of the larger pieces together. It took me about 20 hours to put this greenhouse together by myself. Here are my thoughts about that process and the pros and cons I experienced: As I said above the boxes contain the pieces to specific areas of the greenhouse so it will help to have plenty of room to arrange these boxes accordingly. The instructions are are virtually wordless, pictures articulate the assembly process, and are specific to the smaller 8x8 greenhouse, so quantities need to be increased when gathering the required parts for larger structures. Just keep that in mind as you proceed. As with any instructional set primarily done with pictures pay very close attention to the orientation of the pieces during construction. Each of these individual pieces has a label attached with a part # for easy reference and assembly. They are also water resistant so don't worry if you are putting this together in the rain (as I did), they will stay on and still be readable. VERY IMPORTANT: The greenhouse I purchased was the 8x12 model. However, IT IS NOT 8x12. I made the assumption that I could lay the foundation prior to the arrival and assembly of the greenhouse. This was a mistake as the actually foundation measurements of the greenhouse were several inches beyond that both length and width. As with any product of this nature (i.e., somewhat flimsy), the foundation is the key. So I recommend you NOT set this greenhouse directly on the ground, rather buy enough 4x4 treated lumber to form the foundation and level these out perfectly and squarely. Then, using 8 inch long galvanized screws with washers, fasten the corners to hold this foundation together. Inside for the floor use whatever you desire. I used 16" square red pavers with enough space in between for pea gravel for drainage. Of course you'll want this space to be as level as possible if you do something similar. But I digress. The reason I opted for 4x4 treated lumber is so that I could have a strong and fairly heavy foundation to screw the bottom rails of the greenhouse down to. Each two foot section of the greenhouse foundation has holes for exactly this purpose and you can use 3 inch decking screws, they'll work perfectly. Construction is pretty simple and straightforward. Gathering the required pieces from the various boxes can be tedious. But they go together well and are engineered so that once it is fully assembled the structure will provide adequate strength. I live in a fairly windy area, but the placement of my greenhouse (near the corner of a fence) will provide additional protections. What does give me concern are the clear side panels of the greenhouse. They are flimsy and are only held in place via slots in the structures of the walls. The greenhouse did come with a rubber seal that is supposed to go around each of these clear wall panels to further provide keeping them in place and increased protection from the cold (I assume?), but I have yet been able to install these with any success and for now they lay in a bundle on the floor in the greenhouse until I can come up with a solution. This is without a doubt one of the poorly designed elements of the greenhouse. The doors of the greenhouse is another poorly designed element - at least how to secure the second (french door) if you desire to only use the single door. This door uses two fence gate style slide latches mounted vertically. One at the top of the door and one at the bottom of the door. However, they are woefully designed and to get them to function properly is going to require some creative engineering on my part. Last element of failure on the part of the engineers that designed this greenhouse: they were thoughtful enough to provide a cabling system (4 of them in my 8x12 greenhouse) to hang hanging baskets from. Great idea! Poorly executed. I'm pretty handy, but it is impossible to install these cables as designed. I was able to partially install them so as to make use of them, but I'm not confident with it so I won't be putting too much weight on them. Overall, I am pleased with the greenhouse. And it's going to provide several years of growing pleasure in my backyard. The design issues that I've mentioned aside, it's a quality product that otherwise seems very well thought out and implemented. Would I buy it again for what I paid? Good question. Probably. But knowing of these design faults I would suggest that they lower the price of the greenhouse by about $200. Either that, or go back to engineering and fix these issues. UPDATE 03/25/2022: The greenhouse still stands and it still in great shape. It has survived winters with a foot of snow on the roof. I would recommend removing that much snow as soon as possible, as I could see stress on the structure. But it did hold it until I could sweep it off. Would I buy it again? Yes.
