Joe loved using all the power tools!
Here’s my laundry room with the new walls constructed and new plumbing in place (courtesy of Bryan et. al.). They built new 2×4 stud walls to accommodate plumbing and wiring (as you can see we have interior cinder block walls).
The open wall on the left was actually moved over about 2 ft to make the laundry room smaller (and our rec room larger). Below is the only exterior wall which was spray foamed with insulation.
