Building a garage.
I'm going to have a roof structure with a beam at the ridge. The beam is supported by recessed columns in the walls and one in the garage.
Now, I want to have a small loft in half of the garage and for comfort, I'd like to have a window for this. I want the window directly under the ridge, but oops! :-/
There's a column there!
It's not a big window, 6x6 max 8x8, but it should be in the center...
How to solve this?
A column on each side of the window should work, but what should I use to support above the window?
3 pcs 45x220 nailed together? Order an extra meter of glulam like the ridge beam, 90x315?
Several suggestions, friends and designers..?
/Regards, Linus

Substitution is the melody.
We have a round 1200 window just under our glulam.
Had to substitute it with a steel beam over the window, which then rests on two pillars on the sides of the window down into the foundation wall.
The only option I can think of to solve your problem...

Exactly, others describe it the same way.Linus_Arthursson said:
But you definitely don't need as strong a glulam beam as the ridge beam. With only a one-meter span, you should manage with much less, maybe even 2 pcs 220x45 nailed together, but without knowing what load your roof is calculated to bear, it's impossible to say what dimension you need. I can't do such calculations, but if you're keen to use glulam, there are calculation programs on the websites of some suppliers.
The standing beams may not need to be very strong either, but again, the load must be known if a proper calculation is to be made.
If you can find out what load you have, then maybe, with a bit of luck, someone on the forum can calculate for you. Otherwise, you can (/should?) hire a structural engineer.
Good luck //ML
