I'm going to try to help whomever buys this. I have put it together by myself spending 30 mins here or an hour there. I'm writing this just before the paneling so may edit this review later. (12 x 20)Quick hints for what I learned to help with install:1. The K1 pieces pictured. Notice the one on the right is opened up. The left is how it comes. You will not be able to install it like that. Open it up and it will go a lot easier.2. Use horse stands of first couple of steps which involve the long beams that connect four legs. Then lay legs down and connect the long beams x 2 and stand them up. Then connect shorter beams to connect all four.3. Super important to never fully tighten anything until you are a step or two ahead. I may come back later and be more specific but you will have to manipulate a lot through step 20. Don't fully tighten and torque until done with 19 which includes roof beams.4. The roof beams...to piece L...OMG...even with 4 people that would be stupid. This will be a long answer...so the total height of the kit is about 10 feet at center. The instructions say to mount four roof corner beams (I think "B") to L and then to somehow magically connect the corner beams to the four legs.Can't be done like that without minimum 5 people and it will be tough. The corner beams are so long and heavy when connected to L that it's impossible to lift it at center without all four corners being supported or the mounts will rip through metal. Also one person would have to hold that center piece in the air while four people somehow held the legs and got their screws in.You can see in the picture my solution. I used two suv jacks and built two quick wood stands with 8 foot 2x4s and 12 foot 2x6s top and bottom.With the jacks I was able to center that big piece and raise it up to determine where the proper height was to properly align the corner roof beams. Imagine one person holding all of that.5. Have the short side facing the wind. I obviously mounted this on a platform i built specifically for this gazebo. Longitudinally this structure with everything tight and square (measured corner to corner) doesn't sway at all when I give it some hard leans and pushes; however, the short side shows a little play.In other words if you look at back picture of my home if I try to shake the gazebo towards the house it'll move, but if I do it sideways towards the fence it doesn't. It's bolted down extremely well.I'm not worried about the structural integrity in wind facing this direction.6. Step 19 that refers to strips like g3 g4 g6...etc...do not tighten anything and N pieces go last. Start with G3 and work you way clockwise lightly inserting screw #1 at each of the four red circles. Then in the middle where g6 and g4 meet screw that fully on both sides. Then go back to corners and do piece N. Instructions don't tell you that you should expect g3 and g6s pieces to bend to accommodate the corner. Place N over them and screw it down fully. Then return to the light pieces.Overall, I have started the sheets for roof. That will be tomorrow. By myself, I'd say I have about 10 or so hours in it so far but that included the time of building the stands and taking my time for that center stuff mentioned above.Without a doubt, 5 people with 2 ladders and multiple drills gets this done a lot faster. Even the time saved helping un package and sort parts.Boxes did come damaged 1 and 3 of 5...but that is because they are heavy for one deliver driver to handle. Or maybe even handling in bistro centers.I'd say it's worth the buy. Assuming these sheets for roof go well.
