Windows in corner at new build

[nybyggarn3]

Hello,
I'm planning the construction of a stick-built house. The architect we've consulted wants to place windows in the corners, in several rooms, according to the image below. This includes tall windows from the floor in the living room, "normal" windows in the bedrooms, and long, narrow, high-mounted windows in a bathroom. I think it looks good but I'm wondering how to best achieve this.

I think the nicest would be for the reveals in the corner to meet at the corner. Unfortunately, I'm too bad at drawing to create an image.

The construction of the exterior wall, from the frame inward, will be as follows:
-300 mm light beams filled with cellulose,
-vapor barrier
-28 or 45 mm batten
- OSB + drywall.

My consideration is how to place the windows in the frame for it to look best inside, while also having a good corner. Perhaps someone has done something similar?

Thanks in advance!

I know that @villeg has done something similar in his extension https://www.byggahus.se/forum/threads/stoerre-tillbyggnad-i-egen-regi.318045/

Thanks for the response and for guiding me to your thread! Very interesting. I will read through the whole thing as soon as I can.

Looks like you placed the windows even further into the corner than we planned. Is there an interior picture, or is it too early?

A corner pillar as large as the one on your drawing will interfere with the light incidence in the corner. Minimize the size of the pillar by putting together two studs so that they are only slightly thicker than the window frames. You will have to accept the thermal bridge (quite negligible) that occurs.

A corner post as large as the one shown in your drawing will interfere with the light coming into the corner. Minimize the size of the post by joining two studs so that they are only slightly thicker than the window frames. You will have to deal with the thermal bridge (fairly negligible) that arises.

One issue is that the corner in one of the rooms needs to support a 3.6 m beam with trusses on top. I haven't figured out what's needed for the post yet. I'll ask the designer drawing up the frame to suggest a solution.

I don't think that's an insurmountable difficulty. In the worst case, you can use a 90x90 glulam column. Such a column can handle 50 kN if the height is no greater than 2.5 meters. I have quite a long experience with this type of problem and know that it's important to create a sleek corner.

Thank you so much for your involvement!
I would have guessed a thicker post, at least 120x120. May I trouble you to ask what such a corner might look like?

The size of the column must be adapted to the window frames. The following image is a primitive horizontal section through the corner. The space between the frame and the column must be filled with insulation.
