Shed Build 10X20

[olds]

Gable style, 2X4, 16" OC.
To store yard equipment and fuel.
It snows and rains a lot here, gets pretty windy too.
Going to build it on a concrete pad.
Insulated.

Should I build directly on top of the pad and bolt it down?

Or build it on skids and bolt it down?

Don't plan to move it but wondering if air flow underneath is a good thing.

the concrete is not the floor for the shed?

It's not built yet but I want the floor insulated, so no.

This. Bolt it down if it makes you feel better but make sure your pad is sloped to the drainage point of your yard.

Are you heating the shed? If not, why worry about insulating it? If you have to insulate the floor...then building it on skids is about the only way...allow room for air to flow underneath and for water to run off.
What do your local building codes say on it?

Probably will heat it in winter.
Building dept only care about sq ft. Under 200 sq ft, no permit.

I would probably put it on caissons, gravel underneath. No need for a full slab. sheet the bottom to prevent critters from eating the insulation. 1/4 hardware cloth around the base.
what is your frost depth?

I built mine on 6x6's and insulated the bottom, since there's no way to do that after the fact, so easier to do it then if ever I want to heat it. I also insulated the corner of the walls as there was no way to access those once the plywood is up.

Never tied it down and we have insane wind bursts here sometimes, where it sounds like the house got hit by a truck. We don't really get sustained winds like hurricane or tornado regions though, just bursts that will hit at random. So far so good, it does not appear to have shifted or anything. I was trying to find some of those big auger things you drill into the ground so I can tie it down, and could not find them anywhere and just never bothered to pursue it further.

Made a time lapse of the build if interested, you'll see how I did it. Basically it's just sitting on deck blocks. I assume at some point I will need to shim it since it's not below frost level but it has not really moved at all surprisingly.

What you want is a mobile home tie down auger kit. Should be able to get them on Amazon or at home improvement chain stores.
