Finishing my basement and running into an issue.
I'm totally at a loss as to how to go about building this soffit. To start, I know we identify the lowest point of the drain pipe and it's from that point we build the soffit. Got that.
The part I'm stuck on is I've got a drain pipe that connects to a sewer stack and I don't know how to build around it because on one side I have a foundation wall and the other is a foundation wall with a window. I have a sewer stack on the opposite side of the basement and wont have any issues boxing it in. I'm planning to box it with the dimensions of 14"x14"x14". Trying to keep all things equal, I'd like to carry this to the side I'm having issues with. This is not where I'm running into issues.
My issue: I'm dropping the height of the wall to accommodate the drain pipe and how do I accommodate the drop in ceiling height, build around the drain, and also close in the sewer pipe?
Also, approximately 6-8" to the left of the window is where I plan to build the next wall which cuts back to close in the half bath. I think I have a hold on this part as the soffit would run from the start point back to the other wall which is framed and the soffit would carry into the bathroom and I would then build the wall around the soffit.
One last thing is that I'm dropping the ceiling height by 1.5" due to other plumbing. That being said, I have not yet hung the 2x4s for that and as such, I can use those to tie the soffit into the joists.
I've attached some images below. If anyone has any ideas or can pull a diagram on this I'd greatly appreciate it.
