In a kit usually, you get windows for the crossing of air and light, vents to get rid of suffocation, skylights to enter direct sunlight in a shed, Roofs to protect it from weather damage, and doors to enter the shed and floor panel to keep your outdoor paraphernalia. The thickness of walls and floor sheets and material used determine the strength of the shed. Roof and floor frames also matter to judge the longevity of a product. Last but not the least convenience of assembly is the key factor which determines whether you should buy the particular shed or not.

This beautiful shed comes in a kit of 4 boxes including  6 small skylights, 2 shatterproof polycarbonate windows, 2 screened vents, 2 decorative shutters, 2 peg strips, 2 90″ x 9″ shelves, 4 corner shelves, and a user manual. I do not find anything missed. So far it is good. The color of the sheets is very decent and the material looks fine.
To get started assembly first you need to prepare a strong base where you need to install. You can prepare a subfloor of your choice i.e concrete, wood, or gravel. Then start assembly with the help of another person. Just read out the instruction manual which is very well explained. It takes more than 14 days to fully assemble the shed. If you feel difficulty in assembly you can watch a video
The thing which is most irritating during assembly is the labeling of items. These are not readable. You need to watch pictures to guess what this item is all about. Moreover assembling the shed alone is not a great idea. You can not handle the long sheets, roof climbing, and door notching all alone.

The good thing about both of these sheds that they provide ample space to store almost all of your outdoor tools and gear and still remain roomy. There are many small items that you do not want to place on shed floors like small spray bottles, toolbox, nails, and screws, tapes gardening tools, etc. If you want to use it as a studio or hobby room then floating shelves where you can keep your books, painting stuff, sewing stuff, etc. Well, there is an endless option with which you can customize this storage box aka portable room. You can save space by installing wall-mounted suction shelves, holders, organizers to utilize maximum space. You do not need to buy all things at once. Invest wisely from time to time when you are not tight on budget.
 Lifetime 60138 Vs Lifetime 6446.Â
60138 Outdoor Storage Shed is slightly different in design from the 6446 model. This model material is UV protection which prevents the shed to get heat up, fade, or deshape. The entrance of this shed is a wider  58.3 in. W x 75.4 in. H and bit different in design having door windows that are not present in the previous model. The white squares you see on the top of the shed is a ridge skylight that is build to enter sunlight all over the shed. Model 6446 does not have the ridge skylight that comes with this model (60138). The price of the product is slightly different with a higher trend in 60138 with almost the same design except for skylight. Keep in mind these factors if are confused to buy Lifetime 60138 Vs Lifetime 6446.
Well, let’s get back to review. Let me tell you assembly of this shed is not possible as long as you watch the tutorial video. If you really need a big shed and want to assemble it perfectly so that doors get align. Then my suggestion is that hire a manufacturer team to assemble it for you which will cost you a maximum of $550. You may call 800-225-3865 or email. Â I bet you will give 5 stars rating.
Definitely you can also do it yourself but it requires a minimum of two to three people to do the job. It will drain your energy and time. So be prepared mentally to do hectic work. Well, it is a good adventure. If it suits your nature then do it yourself. It will give immense satisfaction once you get it done. For a larger Shed, it is mandatory to build a subfloor first. Get it ready before the shed kit arrives. The second step is to set up the floor. It is very easy, you can do it yourself by using your common sense with the help of the manual. Then start building walls by reading labels and matching them with user manual instruction. There are some wrong pictures in the manual so be careful. I will suggest you watch the video and follow them. It looks great after assembly.

Best Outdoor shed for Bikes
Suncast BMS8160 is the largest shed in our top 5 list having dimensions 16 feet long and 8 feet wide. It is made of molded resin. Kit includes walls and floor panels, a door with 2 windows, 10 skylights, and 6 corner shelves. You need to prepare the subfloor before assembly. See infographic on how to prepare the subfloor.
The second step is opening up the kit that comes in 3 bags. If you do prep first it will take less time to figure out the steps you need to quickly build the shed. Read labels and arrange the kit parts i.e windows, skylight, doors, walls, and floors with corresponding “JJ” screws and MM bolts. Then collect the tools you need to assemble the shed. You will need a mallet, screwdriver, cordless drill, Ratchet or socket, and wrenches. Watch video here
Assembly of Shed
You have all the accessories to get started assembly. As far as the assembly is concerned it requires 2 to 3 people. I will suggest you pre-assemble the substructure to save time. Use a cordless screwdriver instead of a hand screwdriver because there are about 350 screws you need to use in the whole assembly. Red out instructions or follow a video that would help you out a lot for frustration-free assembly. Then prepare the floor and connect all substructures sub subsequently.
The roof assembly is a bit difficult and you need 3 people to do it correctly. The truss-work feels pretty weak and may get wobbly if someone climbs the roof. Keep in mind this and refer the person with the lightest weight to climb and do screw driving while assembling the roof.
If you are an expert in building you can eventually be successful to build a perfect shed. Otherwise, hire someone for the job for you. There are no extra windows for ventilation or lighting so the shed may get suffocated. LIFETIME 60236Â 18.5 x 11 Ft. is an alternative solution with a larger storage capacity and good design. I love the door opening design which gives you maximum space to let in or out your gears and tools.

The kit comes in 3 boxes. Get your pre-floor ready before the arrival of the kit. The first step is to organize all things and arrange the items to build substructures. There might be some parts missing or broken. Before starting, assembly notes each and everything and call customer services about the issues. When you have full accessories, tools, and kit parts then start assembly.
It requires two to three people to assemble the shed. Assembly is tricky and time taking. Prepare the floor then walls and door. When you prepare the basic structure then the most difficult part comes the roof assembly. Overall it is a good shed though assembly is a bit complicated.
