Lifetime 6405 8' x 10' storage building
The building came in two large cardboard boxes (each one probably 200 pounds). It came on a small trailer truck, but the driver had a very poor handtruck with small wheels rather than large rubber tires. He had to leave it in my driveway, because his handtruck wouldn't roll on soft ground. I had to wheel it to the backyard on my own much better handtruck. The building is a very good product, and the price was much better than at big box stores. I assembled it by myself (74 yr old man) in a few hours each day over a period of several days depending upon the outdoor temperatures. I built a substantial treated lumber platform resting on concrete blocks to assemble the building on. Constructing the base took the most time and effort, because I carefully leveled its supporting blocks. I used five 10' treated 4 " x 4" posts as sleepers on the blocks, and then topped those with eleven treated 8' 2" x 4"s laid flat and then covered with two and a half 4' x 8' sheets of 1/2" treated plywood. I used the dimensions suggested in the instructions except for the length. I used the full 10' length to afford a step at the front door of the building. I assembled all of it with torx head screws - 2 1/2" for the dimensional lumber and 1 1/4" for the plywood. 1 5/8" screws would be better for the plywood, because treated pine is soft and the longer screws would pull the plywood down snugly. The 1 1/4" screws don't have enough threads to adequately pull the plywood down snug in some places. Assembly of the building itself did not take a lot of time or effort, but the assembly instruction booklet is almost entirely pictorial without any textual explanations to speak of. The packets of hardware are poorly labeled, and that caused unnecessary expenditure of time. The hardware packet labels depicted in the booklet are missing on about half the packets, and some unlabeled packets are included inside of other packets. But if you persevere, you will eventually find all of the hardware screws and parts in one packet or another. Careful observation of what size screws are needed will help you to find them. The description of screwing the floor panels together and the screws supplied for the job are ridiculous, but the rest of the assembly isn't so bad once you find the proper screws. Using the word divot to describe where to put the screws in the floor panels is confusing and misleading. They need to rethink the fastening of the floor panels together. The corner wall panels are the most difficult to install; don't try to keep the corner folded and push all the tabs into place at once. Push the tabs on one side into place, fold the other side around the corner and push it into place. A block of wood and a rubber mallet to pound the panels downward are good tools for doing the job alone. The piece of 1" x 4" block to put under the tabs is necessary to lift the flexible floor up to present the slot to the tab. Installing the gable end over the double doors is the trickiest task to do by yourself. It can be done with some clever planning, but having an assistant for that job would save time. The roof can be installed from the inside of the building by standing on a short step stool. There is no need to work from the outside. You can stand inside on the stool and push the roof panels down into place after placing one or two screws from below. It is a good practice to start a screw into each of the holes to tap the threads before hoisting the panels into place. That makes the screws easy to start with one hand while holding the panel in place with the other hand. Aligning the double doors so that they close properly after assembly of the building is better done with more substantial shims than the ones provided. I used pieces of the treated plywood that I trimmed from the base that I built, and I put them between the base and the blocks it rests on rather than inserting them under the rubber floor of the building. That makes the job a piece of cake, and actually works. With all of that said, I would recommend the 6404 building rather than the 6405, because it has large skylights in a couple of the roof panels. The skylights in the ridge of the roof supply some light, but not nearly enough. The increased cost would be worth it. I might order a couple of replacement roof panels with these skylights to retrofit my building. It shouldn't be a difficult task to take the old panels out and substitute skylighted panels.

Well designed and robust structure
Arrived intact on time and Ang the two boxes were placed inside my garage. The instructions were very clear and the drowning acceptable. I’m satisfied with the outcome and the quality of the plastic.

Difficult to put together, floor doesn't go together as easily as some models, roof much easier.
While I'm not an expert at putting Lifetime Sheds together, this is my third shed from them. I have two 7x4.5 ft and this 8x10 one. I'll try to cover the main points that I had trouble with in both sheds with emphasis on the 8x10. It took us about a day and a half to put it together, we were able to do the smaller one in a day. We did 80-90% of the shed the first day, the second day was spent finishing everything up and making it pretty. The floor is supposed to have divots at certain areas so you can put screws in to help keep the floor joints together. There were absolutely no divots to be found. I had to just put the screws in the approximate areas as shown on the instructions, I have no idea if they will have any impact on the flooring. The walls just snap into place. If you are doing it on a dirt floor that is remotely uneven, this will never work. (To be fair it tells you to build a floor/foundation for the shed and not to just put it on bare ground. On the 8x10 shed this is extremely important, on the 7x4.5 shed, this is merely a suggestion.) There are 4 slots per wall section and as soon as you get one or two tabs in, they come out whenever you try to get the remaining tabs. The smaller sheds have holes and the tabs just go into, and then you use a rubber mallet to slide the wall section over so that it locks into place. We eventually just put the walls together and placed them on top of the floor without actually connecting the two together. After the shed was built we bought some L brackets from Home Depot and attached the walls to the floor. It appears to be pretty sturdy, but there's a gap between the floor and the walls that could be problematic when it rains, however it is nice when you have a breeze. The ceiling is amazingly easier to put together. The smaller shed has a bunch of L brackets that you have to put together and line up and the larger shed just has holes that you line up and drill in. Sounds similar in the theory, but amazingly easier in practice. The sunroof in the smaller shed is one 4.5ft white opaque strip at the apex of the roof. The larger shed has 5 thin brown covers that do allow some light in, but not as much as the white ones. You can also unscrew the sides of the sunlights to let a breeze in or more sunlight, but honestly it's a lot of work and probably not something we would do often. The window is nice, however you can only open it 1/2 way or the plastic "window glass" comes out. There are locking mechanisms included, but they are beyond my skill set to install without preventing the window from being able to open. I love all the shelves and hooks that come with the unit, however for the hooks/pegboard it seems like they were trying to give you a variety of hooks to show you possibilities rather than actual useful hooks. Be prepared to buy more to fit whatever you intend on hanging. Overall I love these sheds. They are easy to put together, they fit together well (for the most part) and they seem like they will last a long time. They have stood up to my cow scratching herself on it (that was before we added the brackets) and holds all our horse tack and supplies. The plastic is very similar to the "Little Tykes" quality. Thick double walled plastic that stands up to most everything.

Nice shed - one person install
I read the reviews on here first and decided to go with this model. It took a week to arrive at my house. Free delivery and they put the two heavy boxes in my backyard for me. I never could have gotten those boxes home, much alone moved them by myself. With the boxes in the yard, all that remained was unpacking and assmbly. My pad was already paved, so that lengthy step was not part of the process. I would recommend, if you buy this, go to Lifetimes site, enter the shed model # and look over the PDF of the instructions. That helped me. I didn't think I was going to be able to get it all installed alone, but I did. It took 7 hours the first day and another hour and a half the second to get it weather tight. I haven't installed the shelves yet, so maybe an hour of that left. The roof was the hardest to put on alone, but it is all done from inside on a ladder, so its a matter of getting the plastic panels to line up to be screwed in. It went ok. The last panel took some work to get on, and that was where another set of hands outside would have been a big help. So if you have two or more, this would be easy. Most of the work can be done by one anyway as it's simple putting pieces together, like the doors and gables. I took the advice of one of the other reviewers on here... the latches they supply for the left door ( upper and lower ) to stay shut are odd. Just go buy bolt latches and drill them into the hardware. Much easier. I'm very happy with the way it came out. It's really like putting a huge puzzle together and they did a pretty decent job with the instructions. I recommend this shed kit.

Lifetime 6405 8-by-10-Foot Outdoor Storage Shed
This shed size is ideal for our garden tools, pool supplies and snow blower. The color scheme comes close to matching the house and the total price (foundation+shed) was competitive to me building one with matching siding and shingles but much less time involved. I opted, because of a hill, for the wood foundation consisting of 2x6 joist 16" OC under 3/4" 4'x8' pressure treated plywood and 4x4 posts in sakrete fast set concrete mix. It took 2 days for the foundation using the measurements provided. 12' 6 3/4" diagonal is not stated in the instructions. The shed itself took another two 6 hour days with the wife helping in attaching the side panels to the floor. That would not be fun for one person. I used a Porter Cable screw gun on a very-very low torque setting. We occasionally get deep wet snow so I will brace the metal trusses with a couple of 2x4's from floor to top of the trusses for the winter months and not have any worries. I also used anchor straps on all 4 corners. The recommended lag bolts through the floor just doesn't seem like enough. The quality of all the parts is very good although I'm sure I'll be replacing the upper door latch if it gets some use as others have mentioned. The fit and finish is better than I expected even with all the good reviews. The packing description was a little confusing but it is two packages 8' long and 220 lbs. each. A very nice shed. Update 6/2/14. I neglected to install the roof supports for the winter but it survived two heavy 10-12" snow storms. As others have said, the door latch is not a good design. I will be installing a latching door bolt. This is still a five star item.

Lifetime Shed Model 6405
Purchased 7/6/17 and received 7/14/17 from a freight company. Came in two long boxes on one 6 foot pallet. It weighed over 500 lbs. Driver very professional. He put crate in garage. Shipment very well packed. Several large torn areas/holes on boxes but everything inside okay. All parts okay. Many extra screws and other items - some that are not even mentioned in the manual. I built pad as instructed by Lifetime and even put blocks under corners and down the middle from front to back. Absolutely level and true. It was ready when shipment arrived. Instructions are very poorly written and many details left out. Whoever wrote them has no clue or training in writing instructions/manuals. Had to review many videos on internet and Lifetime website. All helpful but still missing the detailed information that would make this shed easier to put together. Videos show how easily (ha ha) the walls and corners are to put together with each panel 'snapping' loudly together. I had three actually make a 'snapping noise' during the assembly. (Note: if walls male plugs are fitted into the wider end of slots then slide forward, no Snapping Noise will result. Had to cut out excess plastic in some holes in order for wall to fit.) First corner put in okay and long side with window panel okay until I tried to put in second corner panel. The slots for the male end of panel to snap into the female floor holes were 11/2 inches too short. In other words, the top male plug needed a longer/wider hole to fit into. Took wall apart three times and used rubber mallet to make sure the panels were tight together (per Lifetime customer service). Most panels DID NOT snap into slots as instructed by Lifetime. Using a mallet I was finally able to put second corner piece in floor section. So far, just for the shed assembly, three hours with wife helping. Finished all walls and had a friend join us (who had previously put one together) to put in roof and door. Pad and floor still perfectly level and true at this point. This is important as this is the last time the shed is level. Many holes for screws were not finished. For example, many still had hard plugs in the area where it should have had a hole. Quality control seems lacking at factory as processing equipment is not producing product correctly. Had to drill, punch out and cut out these plugs to assemble the trusses and roof. Started assembling shed 6 a.m. and finally finished around 2:30 p.m. This plus about six hours, minimum, to build pad for shed. Some problems with trusses but relatively easy to fix. Roof was difficult to assemble as many holes did not match up when attaching the shingle panels. Remember, the shed pad and floor were level and true after walls were put up. But, the roofing material and trusses had to be pulled and pushed around to fit the walls thus moving tops of wall panels in and out. This caused everything to no longer be level or true as the walls were now not true and when roof was put on, the floor rose up a very small amount on outside edges causing everything not to be level. The two biggest problems are one; putting the doors on and making sure that they fit and are level. The other problem is that whenever you put something relatively heavy (25 lbs. for example) in the shed the floor is no longer level and the doors are no longer level and true and will not close until adjusted. This requires continued application of shims under certain areas of floor (per Lifetime instructions). With this being a forever problem, I will not be able to anchor shed to platform as the shed will not be level and the doors will NOT close. The doors are poorly constructed. There is no real door frame built in to keep the doors level and true so the doors never close easily or in many cases at all. The tops of the doors are either out of level and have to be continuously leveled with shims (as instructed) and are always too close together where the edges are supposed to meet at the door locking mechanisms. Additionally, the bottom of the doors cannot and have never been straight and level. The bottoms always bump into each other making it very difficult to close together. Without a true door frame built in (and it would be easy to make this at the factory) and the gap between the doors where they close not adjustable (only tops and bottoms can be adjusted not the width between the two door panels) because the roof assembly has caused the walls to bow in and out a little, thus lifting the edges of the floor a fraction of an inch off the pad/platform, there will ALWAYS be problems with the doors. A hard door frame would alleviate this problem. The vertical gap between the doors is also very small (wider at the top then at the bottom) making the doors difficult (sometimes impossible) to close. Additionally, the door handle locking plates stick out more than 1/4" on each door edge (right door and left door where they come together) preventing one from either closing the door (when doors are out of level daily) or having to slam door while pushing/pulling right door to the right. These two plates always bump into each other and never slide by each other as they should. (Again having a true door frame would prevent this problem.) I want to anchor the shed to platform (per Lifetime instructions) but am concerned that by doing so I will NOT be able to put shims under shed to keep the doors level. I might try to anchor shed in the future and hope the doors work afterwards. I'll update this review when/if I do. Hopefully, this shed will not melt in our hot climate, sometimes to 105 degrees. Pros: Shed looks good. Has good indoor height making it easy for six foot person to stand upright without bumping head. Plenty of room for storage. Better than the typical thin metal sheds that are really flimsy. Cons: Not a very strong shed so don't put anything of real value in it. Poor assembly instructions. Walls bulge in and out easily (but do spring back) if they are touched or even if a light weight item is leaned against them. Has not rained yet, but there is NO way that this shed will not leak. Even the instructions emphasize drilling multiple holds in platform/deck to allow for drainage. Doors are hard to use/close and need constant adjustment and are very poorly designed. Skylights are odd. Not transparent and same color as roof. If these are not skylights, then they are not needed and roof should be redesigned for easier assembly. Need minimum of three people to assemble and even then not easy to assemble. I've tried to make this an honest review with the goal of explaining problems and providing possible solutions.

A good choice for several reasons
We had to hire someone to assemble it because my husband is 73 and has COPD and several other health issues. It is a replacement for a metal 10' by 10' shed that we got when we moved in here over 7 years ago. At the time we did not know the requirements that our township has for sheds beyond 32 square feet, which is it has to have a rat wall and a concrete pad, so that one had to be rolled off it's place while the garage guy did the concrete work for the shed and then it was rolled back onto it's place. We were never happy with the metal one because you had to bend down to get in it and could not stand up even in the middle of it, and I am or was over 5 feet 6 at the time we moved in here. Plus it got rusty and it was either paint it or replace it, and my husband wanted to replace so I came to Amazon and looked at everything I could. We really wanted the Suncast 10' by 10' but I was concerned it may be more difficult and because we would not be doing the assembly, we would have pay someone for any extra time, so we decided to give up the extra 2 feet and go for this Lifetime 8-by-10 footer. It was delivered around 10:30 this morning and our assembler called before the delivery to ask if he could come out today to do the job, so of course we went with it all. He was out by 11:30 and they had completed it by 6 tonight. It was two guys that did it, he said there was some challenge, but the fact that they got it up so quickly speaks for how well it went together. When it was delivered they used a delivery company called Pilot Freight Services, and I was walking my dog around the I96 service drive like I do every morning, talking to my husband on the walkie talkies. He told me that they had to bring it up in pieces because the top box was opened, I did not understand what he meant until later and what happened was the guy in charge had a new assistant and he had cut the bands on the top box not knowing that what he was supposed to do was cut the bands that held the two boxes together so the top box popped open and they had to carry the panels up to the yard one at at time. I was on the other side of the freeway and my imagination ran wild, but when I got back I saw what happened and all was okay. The panels are screwed together so that part looked like it would not be too complicated. They did have to put the skylights on and the window in, so maybe that made it a little more trying, and that part took the two of them to complete it. It is a great improvement over our metal shed, and we will not miss the extra two feet too much because we had a sort of work bench made out of 2 y 4's and OSB that took a lot of space in the first shed, we gave it to the assembly guy. We used the bench for two window ac's that we got rid of earlier, and also some mulch bags. We could probably put some of the bags in the new one, but will be getting a small horizontal storage cabinet to put alongside this shed to hold the bags in the future. It does feel very sturdy and now we can just hose it down when we hose down the house once or twice a year. The house has vinyl siding. So as far as assembly time, that would be around 6 hours and 30 minutes, which includes taking down our metal shed. They had to unscrew that and load it up in their van, we had emptied it out before they got here except for the work bench that was inside. They took about half an hour to go to Arby's in mid afternoon as well.

Beware of "easy" directions
Delivery was extremely fast, CEVA delivered two 200 lb. boxes into the driveway without any problems -both the driver and his assistant were extremely polite and professional. The shed itself: I will never, ever buy another plastic shed again. The product itself is flimsy, easily dented with a rubber mallet and unattractive. I have built many different pieces of furniture - both store bought and hand produced by myself - this was a test of my patience and a waste of money. Shed was placed on a level PT foundation with PT plywood flooring - the shed flooring itself is very thin and slips --it will have to be anchored to the plywood. Tresses are thin metal -can easily be bent if too much pressure is applied. Polyvinyl walls are held together with wood screws (of all things) - these have absolutely nothing to grab onto and simply slide out!! Roof panels have a tendency to pop out of the tress grooves - again - wood screws are used to attach the vinyl roof panels to the trusses. - Directions were difficult to follow- steps to putting the shed together were not in any logical order - jumped from flooring to walls panels to tresses then to doors handles - oye!! I eventually had to rely on several U-tube videos to complete it. What was advertised as an easy diy has turned into a 4 day painful experience. Positives: It took me 1 hour to unscrew, unsnap and stack every single vinyl panel - this product is being returned ASAP.
