Build shed

[Derbyboy]

Hello,

I'm planning to build a cold storage room. I'm wondering if it's okay to have an overhang of 50 cm from the outer row of foundation blocks?

Hi,

I'm planning to build a cold storage. I'm wondering if it's possible to have an overhang of 50 cm from the outer pillar row?

What is the dimension of the joists, and how much flex/deflection can you accept? I have up to a 400mm overhang from the outer beam on a deck, and then a 2.5m span to the rear attachment (in the house), which works perfectly fine with the dimension 45x170.

Thank you, I haven't decided on the dimensions yet. According to the wood guide's dimensioning program, I can have a 50 cm cantilever with 145 studs, but that's for a deck. Now I'm going to put up a wall out there as well, the roof rests on the wall.

I can accept quite a bit of bending and swaying because it is a kallgörråd in a relatively sheltered location.

I would like to have a 60-70 cm overhang. I can use up to 45x220 as floor joists even though it will be a bit expensive.

The floor joist is supported at the blue arrows and against the wall with joist hangers (blue circle).

What limits/determines the placement of the plinths? It should be cheaper with more or moving plinths and I assume you have already thought of that. Hence the question.

If I manage to create a proper overhang, I won't have to dig away the soil for the outermost plinths. The height is limited, so I want to place the joist as low as possible.

Mm, exactly: If you build traditional roof trusses/straight supports, then the wall and therefore the floor joist will indeed be much more loaded than a deck of course....
Maybe you could build with beams lengthwise instead so that the wall is not loaded by the roof at least?

The shed will be 6 meters wide so it will be difficult.

I will continue digging a bit today and see
