Lifetime HDPE production includes premiere UV-Inhibitors and light fast pigments to make these sheds very resistant to heat and extended exposure to the harmful UV rays of the sun. This UV protection is the best on the market and ensures that Lifetime products will not crack, chip, or peel.

Reviewer: Rich from Contractor   5 Stars

Well Engineered Product. Congratulations for designing and manufacturing this outstanding product. As a licensed contractor for 30 years I rarely see a product that would make me spend the time to write a review. The instructions were thorough and easy to follow, I read the 90 page booklet the evening before assembly. The components are well machined and precise. Every screw went into the preformed extruded pilot hole to ensure a problem free assembly. I work alone and installed the shed in 8 hours on a sand and paver base that I installed the day before. As noted in the instructions a level base is extremely important. I was amazed at the strength of the completed assembly. My customer was completely satisfied with the installation and I honestly cannot list a single con about the product . Well done Lifetime.

Reviewer: TT from    4 Stars

Great Shed. It came in 4 boxes, 1 very heavy box. Took me and a helper 8 hours to set it up and we are pretty handy guys. Can see how it may take others a lot longer. Do not attempt to do solo, a helper is necessary. Set the shed on a level bed of 3/4 gravel and I don't think it's the best base but will be fine. The hardest part was getting the roof trusses together but once getting the hang of the first two it gets easier. The walls snap into place easily and the rest of the installation was a breeze. Great shed.

This kit took a friend and I about 10 hours to assemble. Instruction manual is very comprehensive. We've had massive rain recently and the shed weathered the storm without a leak. Definitely would recommend to friends.

Pros:"Very sturdy","Easy to assemble","Attractive"


Bottom Line:Yes, I would recommend this to a friend.

My 21 year old son and I built this shed in 8 hours. It was pretty simple, but the instructions lacked more detailed diagrams. Blow-ups of critical fittings would have been helpful. I appreciated that they include extra hardware. Nothing is more frustrating than running one screw or nut short. I poured a concrete pad for it, and am glad I did. I imagine building it on anything else could be difficult. The walls are snapped down into the floor, which requires a bit of force, and which could deform any base that is not quite solid. Follow the instructions carefully, and you can't go wrong.
