We have an approx. 10' x 8' x 2" concrete slab that previously held a dilapidated chainlink "shed". While we'd like a nice shed that will match our house and garage we're not sure we have the skills to build it from scratch. And we definitely don't have the budget to have it built. We've considered just putting a large plastic shed there, at least until we get around to coming up with a more permanent solution. Just curious if anyone here has any experience with these things that they could share. Are they water proof? Do they tend to leak? How long will they last? Are there any brands to stay away from? Is it OK to put it directly on top of the slab? I've seen a reasonably priced expandable Keter shed, but can only find one review of it online. Thanks

How much of the joist should be covered by the T-111 siding for a shed that's being built on a patio stone foundation?
