Floating carport - how?

[bultis]

As I hope is clear from the picture, I am hoping to build a carport, but the supports/pillars (the red dots) are in the way of the turnaround area in front. I hope to find some "floating" solution for this, so I'm wondering if it is at all possible and if so, what would be the most suitable solution (durability, cost...)

To make space for the carport, a slope must be partially dug out and L-elements installed (or is that right?), marked in gray on the picture.

The solutions I've thought of are (a) some type of beams shaped like the carport's profile that thereby support the roof. Or (b) straight long beams in the roof's slope and further back down into the ground, perhaps supported by the L-elements. At the furthest point against the house wall, regular pillars are of course fine.

Of course, it must withstand snow. And of course, the entire roof's length (~8m) must be supported.

Madness?
Will it hold?
Is there something similar perhaps even available for purchase?
What might the parts for such a structure cost?
Other tips?

Thanks!!!

Thank you danne_08! Very hopeful! From an image search, I found these for sale in China, but looking at the product description for it, or if it is a very similar one, it only withstands about 50cm of snow, which is not enough, and also the legs on that type of model go straight down into the ground, which is questionable for my rocky/stony plot. I'll have to contact the supplier here in Sweden.

Further suggestions and thoughts regarding my description are gratefully received!

Without support on one side, it creates a rather hefty moment that must be absorbed either in the joints or in the ground attachment if the construction is in one piece.

Don't see anything about how much snow load they can withstand though.

Throwing out a suggestion:

Red is the main structure
Blue is a wire
Black is a concrete counterweight

I constructed a carport a long time ago that resembles your type a a lot.
It used steel beams, I believe it was HEA, that were welded together in the "U-shape" you show.
The lower part of the beams was cast into the foundation slab. The roof had rafters between the HEA beams, and at the top, I think it ended up being roofing sheets.
The HEA beams were dimensioned for dead load and snow load.

In the 90s, some somewhat experimental semi-detached houses were built in Bromsten, Stockholm. The entire frame, including roof trusses, was constructed from something resembling metal studs.

But for these, carports were built with just one wall on one side and no additional support. When they were built, I saw that they had basically just a vertical steel beam in the middle of the wall. It was then angled to form the shape of a roof. From it extended horizontal beams on which roof tiles were laid directly. The wall hangs on a horizontal beam at the roof edge. The wall has no support on the ground.

I never saw how they laid the foundation for the vertical beam, but I assume it is angled underground with one or more beams under the floor.
