I am planning to build a new room in basement as you see in Pic 1.
I need to open a new window (red color lines) on that wall to the outside. There was already a similar window on the left of it (not in Pic 2) which was 70" x 17". I want this new window to be as high as possible near the ceiling. So my question is: what is the minimum width of the header I can do? Assuming I would do it 70" wide as well.This message has been edited. Last edited by: quanghoc,
This is the framing diagram I am planning to follow
First a note on your framing plan: headers that are over 5' (60") wide will require double jack studs on either side. Also, jack studs are continuous and are not split by the window sill plate as shown in your drawing.
On to the header: A lot depends on what is above there as you are on the border between using a double 2x8 with 1/2" plywood filler header vs a double 2x10. By your drawing, either will drop down into the room too far for the look you want. You can also go with steel and will guess that around a 4-1/2" to 5" steel beam will do the trick, but you will need to get that confirmed to meet local codes.
And of course the big question is to make sure that there is open air behind that window area.
The current window in basement has 10" from ceiling to the top edge of the window. So I assume 2x10 was used.
I like your suggestion on steel beam. It could cost a bit more and add 5" max. I have to think about that after I open up the wall. Let me check back in a few weeks with more photos...
So after thinking about this several days, I decided to cancel this project. The layout of this room is just odd / awkward according to many people!!
Just offering some support here....
Are the "many people" going to live in the house?
Do YOU and your family want the room? If so, go for it if you still feel up to it.
There are not many people but we came up with this idea is because 2 rooms were already occupied with stuffs (clothing - due to small masterbed and business). So this is mainly for guests (as there is only 1 guest room now). But we had a second thought because we don't get many guests per year anyways
Dare I say it but you can create the room and use it as a guest room even without a window. It would not be considered a 'bedroom' especially if you sold the house but it could be considered an office or storeroom.
But since you have infrequent guests it could still be used as such without a window.
Thanks for the advise @GardenSprite @Jaybee
