11 x 11 ft Outdoor Storage Shed Building


Are your garden tools and lawn care equipment scattered all over the place? Gather them up and organize them into this attractive Lifetime 11 x 11 ft outdoor storage shed building. This big shed includes plenty of shelving and peg strips to further assist you in having a place for everything, and everything in its place.The Lifetime 11 x 11 ft outdoor storage shed is constructed of UV-protected, high-density polyethylene (HDPE) plastic with powder-coated steel reinforcements. No painting. No rusting. With weather resistance to fading, splitting, and cracking, this is an innovative combination of durability and low maintenance that you're sure to appreciate! 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 11 ft. Shed is rated 4.6 out of 5 by 14.
Rated 5 out of 5 by from Love my shed! Easy and fun to build. lifetime is a good name for it because it has held up well. I bought it about 6 years ago. I had a little trouble with the roof sagging so I called customer service, they asked me to send them a couple of pictures showing the sag. they gladly sent me a few more roof supports for free and it solved the problem. I put pea gravel under the shed, that was a big mistake because years of my riding mower going in and out has caused the gravel to bunch up. Am trying to figure out a plan to slide it off its foundation or disassemble it to replace the pea gravel with crushed rock and re-level it. Great product though, stays clean also, doesn't attract many insects because of the plastic.

Rated 5 out of 5 by from Superman of sheds!! We had the 11x11 along with 2 extension kits shed for 2yrs now and recently had a huge 60ft tall tree fall directly on it. I wish I could attach a picture here to show how well the shed held up. Sure there are supports, roof, and wall panels that need replacing but in all the shed took quite a hit with minimal damage and the contents inside were virtually untouched. Lifetime was extremely helpful with ordering of replacement parts. I can't say enough of how happy we are that we purchased this shed. Not to even mention the fact that this shed requires no maintenance, no wood to rot out over time. We feel this was a great investment! Thanks, Lifetime!!

Rated 5 out of 5 by from Very well designed, with lots of features This is an excellent shed, with many add on features that one would spend more money on to get later. Examples: Sky lights, windows that open and close, shelving, peg boards, full floor. I put the shed on a 12 X 12 foot concrete pad, making this much easier than a wood sub-floor. A few things to expect: The shed took every bit of 8 hours to build with three people. It is well-designed and requires that much time. Follow the instructions in exactly the order described. Failure to do so will almost certainly get one in trouble. Keep your staging area (the stuff in the boxes) separate from your construction area, and only grab what you need for the step you are working on. This reduces confusion.

Rated 4 out of 5 by from Decent shed for the money I bought this on 4/20/2017. It took 2 weeks to be delivered from the department store. It arrives in 4 boxes each of which is like a heavy twin size bed. The most difficult part was making sure I had everything before I started the assembly. It took about an hour to go through the manual and cross reference all the parts to get an idea where all the parts went. Overall it took me basically by myself took 13 hours to put it together. You only really need another person for 3 parts of the assembly. I assembled my shed on a 11 x 11 concrete slab. Your foundation definitely needs to be level. The shed really looks in person like it does online. This shed stores alot of stuff and has plenty of head room.

Rated 4 out of 5 by from Great Shed! Assembly instructions just so-so I love this shed. I installed it on a concrete pad, It looks great and seems quite sturdy. My only beef is with the assembly instructions. There are very few words and the pictures are not always descriptive enough. There was one step that was entirely missing from the instructions (i.e., screwing the wall panels together). Although I easily figured it out, I don't think everyone will. One parts bag was completely mislabeled, so it took me a little time to figure out which one it actually was. Regarding the assembly itself, it was pretty easy, but it took me a good 10 hours, including time to check to be sure I had all the parts. The only challenging part was putting on the final center roof section, but even that wasn't too hard. All-in-all, I think this is a great product and I enjoyed putting it together and seeing it take shape in my back yard. Several of my neighbors (as well as a few contractors we had working at our house) have commented on how nice it looks. They were impressed that we put it together ourselves.

Rated 5 out of 5 by from Filling up Fast We bought this for my Dad's house to store the lawn care equipment, camping gear and tools. We got the bigger size instead of the 8 x 10 because we thought the extra room might be nice. I am so glad we did. We are filling this shed up fast. We even have a few things above the trusses and they seem to be holding up well (they are lighter). He has had it since last spring and it is holding up well through the UT winter with no leaking so far.

Rated 5 out of 5 by from Storage I debated over several manufactures of sheds. I found the Lifetime shed to be the best value for my money. Not only did it arrive at my house in just a few days it was also easy to assemble all you have to do is follow the direction. I would recommend this product to anyone!Thanks Lifetime!

Rated 4 out of 5 by from Nice shed (11'x11') I put it together a couple weeks ago. So far so good.Only downfall was the last two roof sections didn't go together snugly. Additionally, be sure to review the instructions carefully. Some things I had to look over a few times to be sure I got it correct.So far, I like it!

I have owned model #6433 for several years very happily and now see that there is a new shed with the trifold doors, model #6417. Is there anyway of purchasing the front of the shed to change the entrance out. I am very interested. Thank you.   

Asked by: Jestr114
We don't have an option for exchanging those doors out at this time. We are currently working on providing that option.

do I have to make the wood platform or coarse gravel base will be enough?

Asked by: zuhair
For our sheds we do recommend using either a cement pad or a wooden framed foundation. The foundation for the shed needs to be completely level and able to support the entire shed.

I am assembling this shed now. There does not appear to be any seal between adjacent roof panels, how does it keep rain from seeping in?

Asked by: Brian56
Underneath where the roof panels come together is where the truss sits. The truss is shaped into a gutter that the rain would seep into, run down and exit the side of the shed. If you wish, you can use a water based silicone to seal these chanels.

Just received my 11x11. Can you help by advising which box contains the instruction manual. I would like to read it without having to empty every box. Have open two without spotting it.  Thanks

Asked by: Jaybee
The instruction manual for this shed model can be found on box # 4. We do recommend doing a full inventory check before starting the assembly of the shed.

I got a 4" thick 12'x12' concrete slab completed. There's about 3 water puddles after it rained last week. I don't think it's not deeper than 1/4". Would the dips cause a problem to install? Should I caulk the outer edge of flooring?

Asked by: veve8101
The floor panels are roughly 3/4" thick so unless you think you will have water pooling that high you should not need to worry about caulking.
