Pillars and support beams for the shed/wood storage.

[Draven]

I was considering the bearer beams that I have used with 7" and it's just a shed, but the firewood can weigh quite a bit. Maybe better to use 8" 195mm?

It's enough with 45X145, but take what you calculated, just make sure to have some reinforcement under the floor where the firewood will be, plus one or a few extra joists under the floor that support it there.

I think you should stick with 7". I suggested it in my first post and it was based on an approximate calculation considering 12 pillars. The span will only be 2.4 meters. If you go down to 6", you'll have to increase the number of pillars.

I think you should stick to 7". I suggested it in my first post, and it was based on a rough calculation considering 12 plintar. The span will only be 2.4 meters. If you go down to 6", you'll have to increase the number of plintar.

Yes, I'll go with 7". And it will be 15 plintar in total now, feels like it will be stable enough.

Yes, I'll go for 7". And it will be a total of 15 plinths now, feels like it will be stable enough.

Now planning for casting the plinths.
1. How deep should I dig, frost-free in Halland? 1m?
2. Approximately how much gravel and crushed stone do you think in m3?

It depends on the soil. If it is draining (which is common in Halland), half frost-free depth is enough. You can also reduce the depth even more by insulating around the hole.

2. Approximately how much consumption do you think on gravel and macadam in m3?

Not a clue, but it's just a matter of measuring and calculating.
