Hello
I am in the process of widening the garage door opening, which has a "double" brick structure, with the roof trusses resting on the inner brick wall. Currently, the door opening is 2500 mm and not centered on the gable, and the new door will be 3500 mm and centered, so the wall needs to be opened 1000 mm in one direction. There is currently a type of concrete beam with two embedded I-beams with approximate dimensions of 45 mm width and 100 mm height, with a total beam size of 230 mm width and 110 mm height.
Sawing/chiseling up and supporting under the roof truss is not a problem, but the outer brick wall, which also rests on the concrete beam, will be a bit more challenging?

Hello and welcome to the Byggahus forum!
There seems to be an old (<1950) type of steel beam in place there today. The measurements don't quite match modern dimensions. The easiest solution is probably to place a steel beam under each brick wall. Suitable measurements can be assessed with the help of an elevation drawing. Gable walls usually only carry their own weight.
