How do I best replace a load-bearing wall?

[Nickodemussnickrar]

Impossible to assess based solely on pictures. In addition to BirgitS's advice, I would contact a structural engineer to look at the conditions (roof structure, self-weight, wind loads, snow load) to develop a sustainable solution. Alternative 2 could be that a supplier of glulam beams may assist with calculation (e.g. Moelven). Note that interventions in the load-bearing structure require a building notification and Startbesked from the city building municipality. They often also require a certified responsible inspector.

If you need help with the latter, I would gladly assist you. Regards

If you live near Orust, I am very interested in help with this. I am just about to contact a structural engineer based on all the good advice I have received from everyone in the thread.

Isn't an H-beam better?

With a T-beam, you can have the intermediate floor planks resting on something. This isn't possible with an H-beam if you want the bottom edge of the beam to be at the same level as the ceiling.
