Hello!

I've tried to Google back and forth, and my understanding is that when there's a W-formation on the roof trusses, they are self-supporting?
We are in the process of converting 2 small bedrooms into a larger bedroom and the small bedroom into a walk-in closet. (there is a small mini-hall with 2 doors to the respective bedrooms today)
Floor plan sketch indicating walls to be removed in red and new walls with an opening in green, showing the renovation plan for bedrooms and a walk-in closet.
We will need to move the wall about 30-40cm. See the attached sketch where I've marked in red what is to be demolished and in green the new parts.

I've also included some sketches from HomebyMe of what we are planning.
3D model of a home layout showing a bedroom, walk-in closet, and living area with furniture arrangement. The design includes green outdoor space. 3D floor plan of a house including a bedroom and walk-in closet. Person icon in the room, wooden flooring, and furniture visible.
I took photos up in the attic of what the roof trusses look like. As mentioned, we won't even remove the wall since a new wall with an opening is going up. But I'm mostly thinking about whether we can freely remove the first wall and then build the new one, or should we play it safe and frame up the new wall first and then take down the old one? I've also attached some pictures of the hallway itself where we've started to remove the MDF; yes, it's MDF on all the walls instead of drywall.

Attaching some pictures, hopefully, they will be helpful for someone knowledgeable :)

Thanks in advance!

Photographed up in the attic to see how the roof trusses look. As mentioned, we won't even be removing the wall since a new wall with an opening will be built.

Attached some photos that will hopefully be helpful for the knowledgeable :)

Probably not load-bearing. But don't you have any sectional drawings or other drawings of the house?

Provided that it is a single-story house and the truss images show the attic above the current space, the wall is not load-bearing.

Hi! Yes, exactly, it is a single-story house, and what I showed was directly above the room in the picture with the trusses. But the trusses don't need support/wall underneath them then?

Normally not. But it might be good to look at the house plans.

Thanks for the quick response! :) I'll check what I find among the papers when I get home.

Found these, do they make you any wiser from them? :)

It's the right part they're about. Seems to be 1200 between the roof trusses, 3 pcs?

Yes, that helps. As you can see on the roof truss drawing, the supports are drawn at the ends on each side. It is the flat beams under the actual roof truss that are 170mm wide, marked with 1 and 7.
These are the ones that support the roof, so your dividing wall is not load-bearing.

These are what support the roof, so your partition wall is not load-bearing.
Thank you so much for the information!😍🙏🏻 the flat beams under the trusses, where could you read that they are 170mm?
 
If you look at the dimension chain drawn under the truss on the top drawing, you will find the measurement there.

Thanks for all the wise advice and answers! :)
