Using a kit will save you quite a bit of time as well; assembling one of these shed accessories will usually take no more than an hour or two whereas making your own platform can take up to a day. And if you opt for a concrete slab you could have to wait up to a week for it to cure.
Perhaps the most impressive thing about this Arrow Foundation Kit, though, is that it actually provides the best type of base for your shed. Because it will allow your belongings to be stored above the ground, it provides much better defense against damage from ground moisture or flooding than your other options. So, in this instance, the most secure type of foundation also turns out to be easiest and quickest to build.
