Hello! There is a risk of a long text, but I'm trying to include as much information from the start.

A house has been bought here.
Some information about the house.

It was built in 1966 and it's a Jubel's single-story house 98 sqm with a basement. The basement ceiling is made of concrete with a wooden frame and insulation on top, and chipboard with parquet flooring on top of that. The trusses are built with trusswork.

I'm planning to remove walls and create an open floor plan with a kitchen and living room. Started yesterday on the possession day.

Two walls are load-bearing walls that I plan to remove. They are in line with the chimney. One is about 3.7m but is pre-supported about 3m as seen in the pictures with a red steel beam, and the other about 120. You can see it in the picture with tongue and groove boards.

I would like to modify the support so I get 3.7m open and the posts are hidden in the outer wall and chimney respectively. The chimney has a wing that extends about 10cm, so I don't see any major problems there. And in the outer wall, there should also not be any problems.

For the wall with tongue and groove boards, I plan to hide a post on the opposite side of the chimney where there is also a wing extended about 10cm. And use the existing steel beam and cut it to fit.

What I would like input on is what dimension I should have on the support beam and posts. Should I use glulam or steel? Any other methods?

The dimension of the studs in the wall is about 70x50 mm. The posts the beam rests on are 220x70mm
