Lifetime Lockable Polyethylene Storage Shed, 90 Sq. ft., 8' x 12.5', Tan & Brown (6402)

I made a wooden base, and everything went smoothly. I didn't have to adjust the doors or shim anything. The only issue is putting the walls up on a windy day. My wife and I got the whole thing together in about 4 hours, but it would have been less if we didn't spend so much time holding things in place when wind gusts came. I also already had everything unboxed and ready the day before we put it up, which helped us get done faster the next day. Just make sure your base is level and square. Only complaint, but not worth losing a star, is that I didn't find out it didn't come with the anchoring hardware until the end, and that you have to order it separately. I get that you'd use different hardware for a cement or wood base, but that should be asked in the ordering process, so the hardware comes with the kit. All in all, we're extremely happy. We use it mainly to get our three kids' bikes and scooters out of the garage, along with some other things. I love having my garage back. I love that I didn't have to paint anything too. It looks very nice and we're very happy. You will most likely need to build a ramp if you do a wooden base on posts due to being in a frontline climate with ground that's not level. But, you should have plenty of plywood leftover from your foundation and just need a couple 2 x 4s.
