Hello, I have a newly purchased house built from timber just before the turn of the century. Currently, the timber is clad with a lock panel. Enough about that and on to the problem,

The house has been very warm during the summer. This leads me to believe it will be correspondingly cold during the winter. Therefore, I am considering insulating and removing the huge crawl/attic spaces. The rooms inside the crawl spaces are separated by a solid pine wall consisting of 75x190mm thick planks,

The roof trusses are 100x100mm thick and spaced approximately at cc 90. These seem to have previously been supported by the timber wall but have since been cut to create these attics,

It seems that the roof trusses today rest on the thick interior wall. But when I look at the lower floor, there is nothing supporting the interior wall in turn.

My question is, therefore, how can I maximize the floor area on the upper floor and achieve a stable construction. Can I support it with a glulam beam or equivalent, and how should this be done?

You have no use for the kattvindarna other than possible installation space.
I would insulate from the outside with EPS and new battens and tiles!

I have to say that I don't understand the question.

What is the glulam beam supposed to support exactly?
 
I think TS wants to tear down the walls to the attic spaces. You can replace the wall with either a glue-laminated beam or a steel beam, but you must then be able to support the load at the end of the beam. It will be quite large loads to handle. Check with a structural engineer to be safe.
 
Getting a bit confused by the pictures. In the picture on the bottom row to the right, it looks like supports are missing on two rafters. Is the construction already weakened there?
 
Mikael_L, just like Matti_75 mentioned, I want to tear down the current walls to create a larger room. It seems that the previous owners cut not just 2 but all the supports for the roof beams and let the entire roof structure rest on the massive 75mm thick interior wall between the room and the attic space. It seems they have done this since 1957 when the house was remodeled. To clarify the previous construction, I've attached a new image where the top shows the attic space from the outside, and the bottom left is photographed towards the facade, and the one on the right shows two cut supports.

The bottom left image shows a hole with insulation under the window, where I believe a beam went across the space to support the supports. Did it get incomprehensible again? :blushing: In any case, I hope it's possible for a new beam to be attached in some clever way across the space between the dormer and the exterior wall to hold up the roof beams. The space is 4.5 meters long between the exterior wall and the timber wall of the dormer (or whatever it's called).
