If you were really good you would have moved the slab at the same
time. ;)

How you get a slab being cheaper or faster beats me. It only takes a
hour or two to level some blocks for a shed. And costs a few
dollars. Even a 4" slab costs several hundred. And ok, you moved a
shed that was on a slab. Tell us about how you jack hammered up the
slab or do you just have a orphan slab in the middle of your yard now?

Hmmm, it seems that you forgot to factor in the cost of the pressure
treated floor platform for your shed slab/platform comparison.
Probably threw off your analysis just a wee bit.
12' x 12' x 4" slab is roughly two CY of concrete - figure $200 to
$300 for the material cost. Add in some anchor bolts and some 2xs for
the perimeter formwork and the slab materials cost is roughly three or
four hundred bucks.
The same size framed platform would require five sheets of 3/4"
treated plywood ($150), either all 2x12 construction as per the OP's
initial post or three beams with 2x6 or 2x8 joists ($250 for 13 PT
2x12s at 12'), plus nails, pier blocks, etc.
I'm ignoring labor cost as we're talking about DIY stuff, but the end
result is the same. The wood platform would take longer to build and
cost more than a simple slab on grade. If you want to figure in labor
costs and/or contractor speed construction, concrete guys would knock
out the slab in a couple of hours with a few breaks in the middle.
As far as the old slab that Anthony has (or has not), that has nothing
to do with the comparison of the relative costs between a slab and a
framed platform. A friend had one of those "orphan" slabs in his
backyard and we built a new shed on it. You could also use the orphan
slab as a patio, outdoor work area or sell it on eBay.

The only PT I used is the 6X6 PT skids..The floor is KD 2X6s and pine boards
sitting on blocks...Why would you need 2X12s and 3/4 inch PT plywood for a
small storage shed??? What are you gonna do , store a ton of bagged concrete
in it ???LOL... Plenty of air circulation under it and NO rot after 5 years
in Maine...And you're forgetting the TAXES , PERMITS and SETBACK BS for a
PERMANATE shed on a slab verses one with NO tax increase or permits ect for
one on skids and blocks........

There are many ways to build a shed. The OP wrote this:
"I really don't want to build a slab because I am planning
on storing stuff under the shed and hiding it with lattice
all the way around. It will be a good place to put certain
types of things."
Maybe you should set the OP straight and tell him why his ideas for
his design are BS and he should build your shed. Or not. Go with the
"or not".
A few observations:
- I did not recommend a slab. I replied to someone who thought the
slab would be a lot more money than a framed wood platform. Since I
won't be building the shed, and it's not my money or effort, I don't
really care which way the OP goes with the construction. I am simply
supplying advice and experience so the OP can evaluate the
alternatives.
- I did not forget the taxes and that stuff. John G. touched on the
topic and I added to it in a subsequent post.
- I do not know what the OP wants to store under the shed, or how high
off of the ground he wants to go, but I'll give the guy the benefit of
the doubt that after he's settled on a solution that it will work for
him.
- If you've followed this thread, you have seen how the OP started
with the 2x12s to (no doubt) minimize the number of piers. He has
shown flexibility on this. An admirable trait.
- Maine is not exactly rot central. You have that thing called winter
that slows it down a lot. Forgoing the PT joists would doom your shed
in short order in many parts of the country. In two years in New
Orleans, or other termite haven, your design would be infested.
- I am pleased that you built your design that you like. That process
is not unusual.
I do not mind criticism of my posts - I even had one that deserved it
- but it does no one any good when the criticism loses track of who
said what, and gives contrary advice that is specific only to a
certain situation or location.
