How to make a foundation for a load-bearing post next to an exterior wall?
I am going to build a terrace with a roof that slopes along an exterior wall. Because of this, I plan to have posts next to the wall. On these, I intend to place three support beams perpendicular to the wall.
As for the roof, the support beams consist of glue-laminated beams 90x315 on two posts 95x95.
These posts will also have a support beam for the floor, but divided at a third point in the middle. Roof span = 4 m and floor 2 m.
Now I wonder how I should attach the "wall post" since I can't get a support footing so close to the wall.
Do you think it would suffice with some gravel, a concrete slab, and then aim to attach the post to the wall?
The roof will be a 15 m2 sheet metal roof in snow zone 2.

Hello!
How you lay the foundation depends on many factors, such as what the base consists of, the size of the roof, etc.
Why not just attach a horizontal beam along the roof's slope to the frame of the load-bearing wall, on which you can then place the support beams, you could do the same with the floor.

For various reasons, I can't do as you suggest. Regarding the rule for the ceiling, there is a door in the way. For the floor, there isn't enough panel space under the door, and placing it in the foundation makes it too low. So, I'm thinking of laying the lines in the opposite direction.
If I make sure to attach the posts firmly to the wall and sill, there shouldn't be too much load on the concrete slab. But I'm not too fond of the word "should" and didn't study much physics in school.
Here's hoping a happy amateur gets away with everything ;-)

Okay, then I understand.
The question is whether you should attach them to the wall at all, sure if you can hit the frame but I would avoid taking loads on the facade.
