However, it can be tricky to get hold of such timber, and many of the big chains have outright exorbitant prices; the price should basically correspond to the cubic cost.
No, the price should correspond to what the seller considers the right price; if then the buyer purchases, the price is right. Expecting forest owners, sawmills, and timber sellers to sell and only cover costs is naive.

A simple rule of thumb when determining whether you're paying too much for your timber is to look at the cubic price. Simpler products like raw planed wood and battens generally relate to each other as multiplications with some variation. A 45x95 often costs nearly double a 45x45, while tongue and groove 22x95 is closer to half the price of a 45x95. When it comes to more unusual items such as rough-sawn construction timber, prices at larger chains can sometimes be exorbitant.

Or as they say on the internet, "Holy derail batman" (the attitude, despite my lack of clarity, might be more suitable for the local Facebook group's complaint thread).

The posts I was thinking of are about 6x6 inches max... I would have liked to use 45x170 for the roof beams...with a load-bearing beam/hammer beam at 45x195...but preferably 45x170...might be too weak with that and cc 1200...
It's mostly about the risk you're willing to take that the roof might collapse from the snow. The snow load is the dominant factor in the dimensioning. If you are willing to shovel in heavy snowfalls, you can easily reduce the dimensions.

What is the reason you want them slimmer? Is it the price, appearance, or ceiling height? Depending on that, there are different choices you can make.

It's partly about the height and then hand in hand with the appearance. The wall is from the lowest panel board to the highest panel board 3.7m. The height of the windows with the upcoming molding is 2.7 measured from the lowest panel board....

Shoveling the roof is something we always have to do, so we're used to it, but of course we prefer a stable construction!
 
Q
Then you can reduce the cc measurements of the roof beams and place the posts closer together.

With cc 600 and 1500 between the posts, you can go down to 145x45 for both the roof beams and the truss.

If you want to reduce the overall height further, you can mount the roof beams against the side of the truss instead of on top. The most aesthetic way is to mount a 45x45 on the inside bottom of the truss and then place the roof beam on this.
 
Have I understood you correctly?
 
  • Graph paper with a hand-drawn sketch showing lines and measurements, labeled with "45x45" and similar dimensions, possibly for a construction plan.
Q
Yes, it looks like that.

If you want to keep 1800 between the posts, I see that you can have 195x45 C24 as a top plate and then the 45 and 145 will fit in the height of the top plate as well.
 
Yes, exactly! That's what I was thinking! A slope of 60cm at that depth... It will be a bit less than 14 degrees... Can that be okay?
 
Q
From 14 degrees and more, you can use sheet metal, tiles, or felt, so it works fine.

Edit: you mentioned less than 14. Trying to reach 14 or more would be best. With felt applied correctly, you can have a lower pitch.
 
We already have the plåt and it's best for the snow to come off the roof :)
 
Q
You can check with the manufacturer of the sheet metal, but it usually requires 14 degrees (1:4), and if you account for 2000 mm of roof plus 500 mm of roof overhang, you're already on the right track. 2500/4=625 mm.
