  • Good Quality
Size: 11 x 11 Ft.
Looked at several sheds before purchasing this one and happy with my choice. Pros: Sturdy construction, Tall door opening, Assembled nicely, Was able to assemble mostly by myself, Parts are light weight and easy to handle by one person. Cons: Assembly instructions started out detailed but by the end who ever wrote them seemed to lose interest and at the end I was left to guessing on some assembly steps and parts. Window assemble and operation need some upgrading for proper use. If you need to supply your own plywood platform, as I did, it would have been a better design if they would have took into consideration standard size plywood sheets and had it fit them, only three and one half inches smaller in each direction would have done it and would save having to buy a extra sheet of plywood to complete the platform. Overall though I am happy with the purchase and recommend this item. It took about forty man hours to purchase, cut the materials, assemble the platform and complete the assembly of this shed. ... show more

  • Great product!
Size: 11 x 13.5 Ft.
So far, I'm loving this storage! It's well-designed, sturdy, and looks great. Paid no shipping and taxes which is great! I used Amazon to hire an installer who did a great job. He was not fond of the installation instructions and complained a few times about the order of installing things as shown in the manual, part labeling, poor tolerancing/alignments, etc. I advised him to provide Lifetime with his feedback. It already rained fairly heavily here, but I have not noticed a single drop of water inside the storage, yet. As most people have alreay mentioned, the windows look and feel very flimsy. I will update this feedback in a year or so. ... show more

Size: 11 x 13.5 Ft.
Met my expectations. Exactly what I anticipated. Delivery was 8 days early. Reading and fully understanding installation instruction made for a very easy assembly. Extremely satisfied with this purchase. Site on a slope - utilized 9 concrete footings, 2x6 platform frame with 2x4 intermediate framing. ... show more

  • Easy to assemble only if you have help
Size: 11 x 13.5 Ft.
This shed is beautiful and sturdy but it only looks nice after it is fully assembled. The instructions said this shed should be put together by 3 people. Actually, 2 people can easily do it. I put it together mostly by myself but I had to have help with the front and rear gables because it is not possible to do this step without help even if you do one piece at a time you still got to deal with the screen vents so it takes 2 people for this step. Everything else can be put together by one person, the trusses have to be done one small piece at a time if you don't have help, it is tricky you have to improvise a lot without help. ... show more

  • A shed so nice, I'm thinking about moving in!
Size: 11 x 11 Ft.
Great shed. Very well constructed materials. We had our contractor build it. He complimented the overall quality. Looks great in our backyard. Great price. Delivery was on time and the freight company was very helpful with delivery and placement. Better price than Home Depot.

  • 6433 11'x11' shed review
Size: 11 x 11 Ft.
I built the 6433 last week to replace an old aluminum shed that was too small. The 6433 required a larger base, so I had to add some pavers to extend the patio out some to accommodate the larger footprint. I thought I was careful in making sure the base was nice and level. If possible, I would recommend that you pour a new concrete base (carefully leveled and just an inch or so bigger on each side than the base of the shed). From what I've read and experienced, if you are going to have problems building this shed, it will be caused by a base that's not level. Parts are well labeled and instructions fairly easy to follow. Took me a day and a half to assemble. Everything went smooth until I got to installing last couple of roof panels. They did not immediately align. Lifetime tech support said this is a common problem for DIYers and recommended that I loosen all of the roof and wall screws to allow adjustment, then re tighten. I loosened them, but couldn't realign by hand. I had to use a come-along attached to top of last metal side wall support (run out opposite window and attached to a tree) to pull the truss into proper alignment. Then the last two roof panels fit perfectly. Only other major problem encountered has been aligning the doors. Right door works fine, but left door is too low (about 3/4"). I watched lifetime video on door adjust, which recommended shimming the shed in spots, but that didn't make slightest difference. Still haven't figured out how to fix - I may have to drill new holes in hinge plate, slide entire hinge (and possibly door top plate) up a half inch or so and screw it back in place making new holes. Tips: If you don't want people to be able to look into the shed, leave the opaque film on the plexiglass windows before installing. I don't really see the point of the operable windows anyway. For better security, I'd prefer that the side windows be fixed shut. I don't plan on opening them. Leave truss screws fairly loose until entire roof is on, then tighten them down. Might want to use handheld screwdriver for installing screws into any plastic. Too easy to over torque using a drill with a Phillips bit. Overall, shed seems to be very well designed and instructions easy to follow. I suspect the alignment issues I encountered were from my base not being perfectly flat. ... show more
