This is the answer to the question Is it a concrete canopy? Or is it wood/aluminum?
Revision 1
You could also call it on-site fabrication: that is, formed/welded/created at the construction site. I would probably assemble the pipe in the example photo from concrete, aerated concrete, steel beams, square pipes, and drywall.
This can also be done by a carpenter, for example, with columns of beams lined with plasterboard (cross-section including plaster can be less than 30 cm). However, the connection of these columns to the floor will be "non-trivial".
However, keep in mind that the carport in the example photo you used, in terms of budget will come out golden.
I wouldn't want to cover the space with such a carport, because the house needs light, and visually the main entrance becomes a side entrance, if only because of the "hidden" location.
