The main floor has 9′ ceilings. We are leaving all the height except for the bathroom. Yesterday and today I installed 2 x 4s for an eight foot ceiling. The lowered ceiling will allow Steven to install the plumbing above the ceiling.
I had to redo two joists because the 2 x 4s were warped and I didn’t want the sheet rock marred. Steven worked in the basement on plumbing and electrical.
