Hi guys I havent been around in a while, I hope all is well.
SO I have to build a 12×12 on a slab. I have 3 areas Im wrestling with.
1. I wanted to use LP Smartside since it comes primed but then I have to cut in let in braces since its not structural. That or T-111 does double duty but needs priming.
2. I was thinking of using treated 4×4 sill on the slab then regular 2x on top of it. Im thinking of the rain splatter at the base and a 4×4 would be more durable than a regular 2x sill. Adding the extra sill allows future replacement.
3. The doors The plywood for doors with angle iron on inside perimeter to prevent warping and keep it light or 2x framingI know it elementary stuff but I can overthink the littlest things LOL so I always welcome hearing thoughts

I build a lot sheds, it seems. 😆
I use wood we mill ourselves up at the ranch for a lot of ranch buildings, and because of that, I have to use let in bracing.
It works, but it makes the inside funky. Unless you’re doing wall covering on the inside. And it takes longer.
I’d rather spend the time priming T1-11, over cutting in let in braces, personally.
My hands down favorite ay to do utility/outbuildings, is with a course or 2 of block, and the walls on top.
True, you have to lift the walls up on top of the block, but for short walls, it’s not too bad.
It makes for an extremely easy to clean interior, and eliminates wall rot on the outside.
I always frame my doors just like a residential unit.

I recently build a shen on some blocks too. It worked well. I use a 36″ steel entry door and steel studs with LP smart side on the out side.

Interesting. Never see block at least not on Simple sheds
Mostly prefabs here cheaper than I can build often. craned into the yard

LP has a product in their Smartside line that is stranded and comes in sheets like T-111 that you can get primed from the factory and it will provide the shear you need for the walls. It was made for tract builders to use as a siding and sheeting combination .
https://lpcorp.com/products/exterior/siding-trim/products/panel-vertical-siding
In the link, the Cedar Texture is footnoted that it is a fiber product and not approved for structural use but the other 4 options are not footnoted and a stranded product and approved for structural. If you click on the other options the footnote goes away. The website is a little misleading the way it is set up. My Neighbor used to be an LP rep so I would get all the information on what they were doing with their products from him. I do remember him saying the stranded product is a rated sheeting also.
As for the treated 4 x 4 on the slab, we typically lay a 4″ x 4″ block around the perimeter of the slab that is dowelled into the slab and then frame our walls on it. It keeps everything out of the water and gives the exterior a good separation from the siding to the dirt.

The blocks were already there and that why I built on top.

Good call on the LP stranded, didnt see that option
What to you mean doweling 4×4 block? Just mortar and random anchors?
I have a 13×13 slab and was going to build a 12×12 or 12-6 x 12-6 so I have some edge distance for soil

Here’s a couple of pics of some I’ve done.
First is actually a garage, but same deal.
Second is on pier blocks, with 4×6 PT skids below.
Third is one I built up at the ranch, completely from wood milled on the property. Is has diagonal bracing inside. I set it on 16×16 poured concrete footings.
Fourth is actually a chicken coop, but I did the block perimeter on it. Just has a dirt floor inside, but it would be easy to pour a slab inside.

Nice work Seven Delta.
I have to resist over building a shed and turning it into a cool little house. I have a 3k budget.
I would use strips of APP rubber under those deck sleepers btw.

I think you are better building to the edge of the slab and allowing water to run down the wall and on to the ground. anytime I have seen a concrete ledge outside the walls, there is a chance for water to get under the walls. In some way it works it self under the wall when the caulk fails

Same here , either on a concrete pad or a typical 2x material framing , some do it in PT floor framing , or just plain old 2x I have done a few with concrete pads , just nail or screw down the sill to the pad , as for the exterior , it’s either aluminum or pvc siding and laps over the edge of the concrete pad , so no worries about that bottom plate sitting in water ?
If that’s what I am understanding.
How would that outside be finished.I would use strips of APP rubber under those deck sleepers btw.
Not familiar with that product. What is it?

I couldn’t agree more. For some reason my summer place is on a slab and they left the back wall 2 ft short of the edge of the slab. When I opened up that wall I swept up the bottom plate, it looked like potting soil.
Well there is such thing as eaves.
I get the thought process though and I could see that happening I probably have it as well.
I was actually thinking of doing a bottom band of one by with drip edge to protect the siding.
A couple of pieces of boral 4 trim won’t break the budget.

Those are really nice. Much bigger than what we would call a shed. Maybe a ADU and they would all need permits.
I wish I had a shed that big. Mine is 6’6″X8′

Thanks you!
Some of those did need permits.

We can build up 120sq.ft. with out a permit if it cost under 1,000$ really can’t hard to do. Then we have to keep the 5′ setback rules.

Five feet eh! Here, to prop line/fence, it’s 2 feet.

I’ve seen that as well. Good advice to let the water drip on to the ground rather than on the cement.
