I am planning to open up to the ridge and start by installing a ridge beam to avoid looking at a lot of trusses when in the room. This will be supported by a pillar running along the short wall down to the footing and another that is placed where the chimney is today (it will be demolished). The house is one story with a basement and an attic (which will disappear).
As someone completely without knowledge, I wonder if it is not possible to use a shorter pillar in the "attic" that then stands on the short wall instead of taking it all the way down to the footing. Of course, the load needs to be distributed. Is this possible?
Bonus question.
Can you have a ridge beam that is 12m long without support in the middle? Assuming HAE/HAB of "reasonable" dimension.

Hello Nizztos! With simple mathematics, the short walls need to be reinforced up to double strength because the total number of load-bearing walls is halved with a ridge beam. And with the same logic on the short column, you need to replace the lost side stability with equally strong diagonal metal braces in the roof, or whatever it’s called. All strength that is removed must therefore be replaced in one way or another. This is called in a roof construction that "the contractor is responsible for the total stability of the roof and the building." And that it is the basic structural stability of the building's frame that ultimately determines how strong the roof becomes. How long you can make a ridge beam, I do not know. But I think long ridge beams are most common in combination with lightweight metal roofs. It is probably best to ask a roof constructor! Best regards; PerOF
Constructor will be used but for 1000kr / started hour you want to have a bit of control yourself first.
