Building a soffit around a drainage pipe (contractors, moving)

[ssudha17]

I am trying to build a wall around a drainage pipe that goes along half the length of a wall close to the ceiling. I would not like to waste all the space by moving the wall in by 6 or 7 inches to avoid the pipe. I am attaching a picture of the pipe in my basement to describe my situation.

I was trying to figure out how I could work around it without having to lose much space. Should I move the pipe into the room to build a soffit around it or should I attach a treated 2x4 to the concrete wall and then use that to attach one side of the soffit and then build the wall underneath the pipe touching the bottom of the soffit?

Is that allowable from a New jersey code perspective? Does attaching a 2x4 to the concrete wall pose any structural disadvantages that I need to consider? Are there other options?

Use larger studs... 6x6 instead of 4x4...brings the wall out a little further and the pipe will end up behind the wall

Hire a contractor. They can probably do it in less time, and the job will be done right. Use only licensed contractors, get a permit for all work, Do NOT hire anyone who uses illegals.
