I have a split-level house and one room too many, so I'm thinking of converting it into a garage, about 25 sqm. I've gotten approval for a building permit for the change of use, and I'm about to take down an opening in the outer wall but thought I'd consult with you experts first. I'll attach some pictures and drawings.
There will be an opening 2.5m wide and 2m high for the garage door. The top edge of the windows is now at 2m, and the windows together have a width of about 2.35, so the opening will be slightly wider than the windows, otherwise, they are a pretty good template for how the opening will look.
The room is 7m "deep" and 3.5m wide, so there shouldn't be any joists directly above the windows, right? It's also prepared for at least one doorway where I plan to have the door since there is a light switch for both the ceiling lamp and the facade lighting on the wall in the corner.
Possibly, the post between the windows is load-bearing, and there is likely a beam above the windows. Tear off the wall covering and take a look. You may need to reinforce the beam above the future doorway.
It might be possible, but I'd prefer not to have to tear upwards above the windows as the height is finished and I'm not sure how I would patch it up nicely afterwards.
Would it be possible to just attach a small frame in the opening?
Clear as thin sausage stock that the outer wall is load-bearing. As a previous writer has already suggested, there is probably some form of beam work above both windows, or alternatively, the beam work is built into the intermediate floor.
