House is a two-story four-square, built in 1903 of 3-course brick and oak joists/studs. On previous renovations I have noted that at least some joists are supported on one end by the brick and the centerline of the house (which is supported by beams in the basement) on the other end. I do not know if this is true for all joists in the house, although I suspect it is.
I want to put an archway through an interior wall from LR to DR. This wall runs parallel to joists in the basement and second floor, so I am pretty sure it is not load-bearing. Inside the wall, I see that it originally held pocket doors, with the original opening being 6 feet wide and framed by double studs on either side. Original studs run to the ceiling (10 ft.) and appear to be under a joist. Pocket door railing is nailed to something above it, but so far I can't see what that is.
I could live with the 6 ft opening, but I would really prefer to make it wider, which would mean cutting the double studs on either side. Would those double studs have been used for reinforcing the opening for the pocket doors only and not necessarily for "supporting" the joist above it?
In other words, given the construction of the house, would a header be necessary for this wider opening?
Thanks, Dee
