I want to expand the free space for the bathroom in the attic, there was an idea to remove the rafters legs, cut a beam, 100h150mm in the timber facade, and on the left rafters to fasten to the support post. Is such a design is sufficiently strong? The distance between the rafters about 90 cm.
You can, but the cross-section of the beam must be calculated, and it is not clear how this structure will work during the shrinkage of the gable.
