11 x 13.5 ft Outdoor Storage Shed Building


This attractive Lifetime 6415 shed is a backyard attraction that has as much style as your house! You’ll appreciate the windows, skylights, and spacious headroom of this design. Lifetime’s 6415 shed comes with plenty of room for the big stuff and a shelving system and peg strips for the small stuff so you can find what you need, when you need it. Lifetime 6415 sheds are designed for style and durability. Constructed from high-density polyethylene (HDPE)plastic with sturdy steel reinforcements, our sheds are weather resistant to rusting, fading and cracking and never need painting! For routine cleaning, simply spray down with a hose. Made in the USA from US and imported parts. Compatible with our 11 ft expansion kits.

Consult local building codes before assembly.This shed must be built on a flat level foundation of wood or concrete (not included). Flooring must be anchored to the foundation. Anchoring hardware depends on the type of foundation you have and is therefore not included in the shed kit. Not including the installation of the foundation, you can expect assembly of the shed itself to take 2 adults up to 8 hours.

For more information about assembly, read the Owner's Manual Sample and watch our helpful video on How To Build A Lifetime Shed. (Components will vary between different models).

11 ft. x 13.5 ft. Shed is rated 4.7 out of 5 by 27.
Rated 5 out of 5 by from GREAT PRODUCT Purchased shed last year, and was put up last fall. It can't be stressed enough of making your deck or pad level. As you go up the mistakes of not being level are magnified at the top! I put in a concrete pad, making it 1" longer and wider than the footprint. I put a rounded edge on the pad. Any rain runs down the side off into the gravel I have around the pad. The shed is water tight! I did not do any caulking. I did secure the shed frame down with concrete screws. I will blow down when my house blows down.The finished product is very strong and pleasing to the eye. It is money well spent as long as your going to put the time in leveling out your foundation.

Rated 5 out of 5 by from Shed Review--A good buy for me. Bottom Line:Yes, I would recommend this to a friend. I bought this shed last August, and I'm happy to have done so. There are many pages of instructions, and MANY bags of small parts, and many similar looking shed components--somewhat of a drawback. I built it in my spare time over two weekends, plus some time during the weekday evenings, with help from my 13-year-old son. It was a good father-son project. A surprise was the floor. I knew it came with one, but it was not sturdy. Poured concrete would make the best base for it, but the instructions note that a 2x4 floor frame covered with plywood would work, as would a well-smoothed and packed fine gravel/dirt base. I went with the wood. There were no surprises during setup, although some of the instructions could have been rewritten to improve clarity and comprehension. Some parts look much like others, and we ended up using the wrong parts in some stages and had to remove them because they were required in later steps. When finished, this shed looks great and feels solid. During a snow & wind storm on Christmas, a large conifer fell squarely on the shed. The trunk of this tree was about 14" in diameter. One branch broke through the roof and held the tree there. It wasn't too much trouble to cut off the overhanging part of the tree, then cut the trunk, and finally slide the remainder off the roof. The hole made by the branch was about 2" wide, and some caulk and a temporary wooden plug fixed it for the winter. Now I just have to order a new roof panel to replace it. I'm happy with this shed, and wouldn't hesitate to purchase another just like it. The tree hitting the shed weighed several tons, but the shed didn't buckle or bow or move--a testimony to the steel supports in the walls and roof.

Rated 5 out of 5 by from Excellent all the way around Pros:Durable,"Looks good","Easy assembly" Cons:"Pricey" Best Uses:"Work Shop","Storage" Bottom Line:Yes, I would recommend this to a friend. I bought this building from a local [...] in June of 2009 and am just now getting it put up in February 2010. It sat outside in four large boxes for all this time, and to my surprise, was still in perfect shape when it came time to assemble it.I am overall very pleased with the building. For the amount of material and the amount of assembly involved, I believe it was a little pricey, so shop around and look for special sales, etc. I have mine laying on a concrete pad. Preparing a level, solid surface is the key to getting this building together properly and without a lot of adjusting, pulling and tugging. The directions say it takes two people to assemble the building in the time frame "the better part of a weekend.." I assembled mine right by myself in about 4 hours one day, 8 hours the next, and maybe 2-3 to finish the final touches. EVERYTHING comes unassembled, even the door hardware, so be willing to take some time. Follow the directions carefully, and when tightening screws, most of them are going into vinyl, NOT METAL, so don't overtighten! Again, this is a nice little building and seems durable. You might be able to build or buy a wood building kit for much less, but the advantage to vinyl is the fact you can pretty much wash the whole darn thing down, inside and out, and never worry about painting it, or it rottening. I'm overall pleased with this product.

Rated 5 out of 5 by from great looking shed I bought this shed cause it being all vinyl It will last a lifetime the looks of it .it sure will. I built it on a wood deck of all pressure treated andi am glad I did because you sure do need a nice flat surface to have it all come together it took me about 14 hours to assembly and the help of one other person for about a half hour it is all up and ready to be used but the only thing I didn't like us the directions some parts I f it can be a little confusing but took a break and when back at it and figured it out thanks for the great product I will enjoy it

Rated 4 out of 5 by from Great value for its competition & what I paid. I did a lot of reading before deciding to purchase this shed online. I ended up getting it on sale for $1605 shipped from Wayfair (used 10% coupon when the price dropped to $1783 - no tax). I wanted a Vinyl shed that would not need to be built on skids because I didn't want to have to re-shingle or re-paint it in the future and I didn't want any animals living under the shed. As you can see from the pictures I ended up using pea gravel inside a box made from railroad ties. I leveled the pea gravel the best that I could using a laser level and spinning it around little by little to check the height from the middle. On to the shed... I spent about 90 minutes reading the manual before the shed arrived. I ended up downloading an older version of the shed instructions that I found helpful to use with the updated instructions that came in the box. A couple of the diagrams from the older directions were useful although most of the pictures from the new (updated) directions were better to use. There were a few times that were confusing about which way the parts were supposed to go - an example would be the door frame pieces could use a better explanation on the orientation in the picture. One of my door frames was "punched" an inch too high from the factory but lifetime sent me a new piece via express delivery from Fedex. Lifetime tech support was great each of the 3 times that I called. It's not that I was having trouble but I wanted to make sure I could put the windows and skylights on the same side and not affect the integrity of the structure. I'm in the northern hemisphere and the doors face 120 degrees southeast so the sun is only on one side of the shed and I wanted to maximize the light. I spent about 10 hours putting the trusses together along with the door hardware and lock mechanism and skylights. I did as much as I could by myself - the floor was challenging by myself but if I used concrete I think it would have been easier. Once the floor was level and down, and the doors and trusses were pre-assembled by me in advance it took 4 people 6 hours from start to finish including stopping for breakfast and lunch. It was myself and my friend and we had a couple of tall neighborhood kids there to help hold the walls while we screwed the screws as well as get up on the ladders to help hold the roof panels in place as we screwed from the inside. I don't care how many reviews you read on here or Amazon or Homedepot/lowes website, there is no way that someone put this together completely by themselves unless they're god. One piece of advice that I read on Amazon and was helpful would be to put the roof caps on immediately after you put both sides of the roof on while there is an opening next to it so you can reach easier. If I was able to make improvements to the shed I would think about the clips that hold the windows in place - they are terrible. I called Lifetime and they sent me replacements to try since the ones I have don't "spin" freely at all. I would definitely recommend this if you are looking for a shed that seems like it will last. My father laughed at me when I told him I was buying this - he said my shed was going to be built out of the same material that my 4 year old's play house was made from but he retracted his statement at the end; he was impressed with the final product. I didn't screw it down because it is heavy enough not to go anywhere. Also a few reviews talked about ABT delivering the shed. I had a very positive experience with them and scheduled the day/time I needed and the driver had the proper pallet jack to bring the pallet down my driveway and place it in my garage.

Rated 5 out of 5 by from Way better value than Tuff Shed I have two neighbors with this exact shed and I am absolutely in love with it! I'm currently saving up to buy my own. They are designed well and they really hold up. We had a funnel cloud rip through our neighborhood not long ago and neither of them budged. These are a fraction of the cost of a Tuff Shed, and they are just as good if not better. You don't have maintenance on them like most of the other major shed brands. Very impressed!

I would be possibly be parking a large motorcycle (one is over 800 pounds) or two in the shed.  Any idea if the floor will hold?  

Asked by: thegreencantina
The floors on our sheds are rated to the following: 30 lbs per sq inch / 5,040 lbs per sq foot. As long as the foundation that you use for the shed is fully supporting the floor it should be able to hold with no problem.
