Shed/Storage/Shop Flooring options?

[EW57]

I’m in need of some additional space for toy storage & am looking for some suggestions. Currently I’m thinking of a 24x12 gambrel style shed (15’ tall) with a 4’ overhang similar to the attached picture.

I’d like to have this be a >20year structure and am concerned with the longevity of wooden flooring. I originally thought of going with around 21 10” sonotube piers, but I’m concerned that the floor will be too far off the ground, as I’d like to be able to store lawn equipment & a few bikes/atvs.

Would a slab be a better option? If the math is right, a 6” slab would be about 7yards.

Is $7500 (approx. $25/sqft) pushing it? Seems like a lot for a shed…

Any input would be greatly appreciated!

for wood to last it has to be kept dry and uneaten by insects.
You do both and wood can last for over 100 years
slab is the best floor in my opinon for a shed/garage it does not bow/sink with weight

I built my 12 by 16 shed like a house over a crawl space with a rat wall as a footing about a foot above grade and four foot down. I used pressure treated wood for the floor joist and pressure treated plywood for the floor. In Michigan cement doesn’t hold up and the wood floor makes for easy additions like electrical. A few years ago I added a three way circuit to be able to turn the sheds outdoor lights on from the family room. I addressed the moisture issues before building and after ten years it has held up while.

Are you looking to build it yourself, wondering if the $7500 is what you want to spend or have budgeted. If you do it yourself, I think that may be doable but I'm not sure what that siding would cost compared to sheets of T111.

Treasureseeker, curious why concrete doesn't hold up in Michigan?

For such a nice bldg, I would do concrete, hands down. Just make sure you prep the area and pour it according to the weather in your area.

I think your math is off.

6" thick, 20' long and 12' wide should be about 4 1/2 yards.

oops, just noticed the 4' overhang. If you concrete that too, it should be under six yards.

Although, I don't think I would pour it 6" thick, I'd probably pour it 4" and be done. Like I said though, depending where you live might take a little more concrete for some pier work or a monolithic pour.

I like it ALOT. I would do it on concrete, probably 4" with at least some beams and at most some piers.

How would you handle the door? The door layout as shown would be unworkable, for getting mowers, bicycles, motorcycles, and ATV's in and out.

A garage door or a bay door would add much functionality.

Thank you everyone for the input! I intend on doing as much myself as possible, I need to talk to the powers that be on where to see where a "shed" turns into a permanent/permit requiring/tax assessing structure, hopefully here within the next few weeks.

The attached picture is much nicer than I intend, I have planned to side it to match the house (havent priced that portion yet).

I dont plan on having any windows, functional ones at least, and for doors, I'd like to have a walk in door centered, similar to what is shown, & then two 7'x7' (approx) sliding doors on either side of the walk in, sliding towards the center.

The intention is to have a wall patitioning the space into a 8x12 for yard tools/mower(s) and then the 16x12 would be for toys.

Thanks again!

Most often a concrete slab makes a shed "permanent" and therefore taxable.
Dug in posts as piers is a maybe depending on the local rules.
Setting it on cement pads with a food floor is almost always "temporary" and not taxed.

Damn, that is not a shed, that is a garage!!


Isn't a shed something that is free standing as in no foundation or concrete slabs? I think that is how our city has it lined out... the moment you put concrete down you need permits like crazy.

I am in the process of building a 12x28 gambrel roof shed. Gravel base, 4x4 "skids", then built the frame with PT 2x6 in 3 sections, joists 12" OC. Tied sections together with 2X6 PT band boards, 3/4 PT plywood floor. Walls are 8' tall, gambrel is about 6' high. Possibly a bit "over-built", but I have a lot of stuff to put in it - 3 lawn tractors, 3 lawnmowers, 2 trimmers, generator, chipper, parts for 4 project cars...........

If you were making something that nice, I'd do it right, concrete the floor and pay the taxes on it. I'd stay away from the sliding door for the "toy side" if you plan on being in there in the winter. I don't think they seal up like a regular garage door.
