Hello. I am going to open up a wall. It is about 2 linear meters that need to be opened up. A little more or less depending on the position of the studs. In my house from '68, there is about 45/60cm center-to-center between studs. I suspect this is a load-bearing wall. There are two parallel load-bearing walls running through most of the house, including where I want to open up. The main body of my house is 15x8 m. These parallel walls run approximately 7-8 linear meters. Finally, there is a load-bearing wall separating the kitchen and living room.
My question is, how should I determine the dimensions of the beam/studs to support this opening? I have a gable roof with a 15-degree pitch. The distance between the trusses is somewhere between 80-100 cm.
My thought was to laminate/screw together two pieces of 45x195 (or 45x170) that lie over one (or two laminated/screwed together) standing 45x70/45x95 studs. Alternatively, purchase a glulam beam in a suitable dimension.
I have built garden sheds before and renovated roofs on garages and sheds. I usually over-dimension trusses and load-bearing studs for safety reasons. But that was for areas of 10-20 sqm. Now we're talking about my house and load-bearing walls. So I would like to get some input before I start. I can post pictures and a floor plan too.
