First the cutting around the door.
Next is the pipe from the second floor.
I wanted to cover that pipe, but also have a hole so i could reach the inspection lid
On top of that I had to struggle with radiator piping.
I made the decision to cover it all.
Mostly because there was not room enough between the pipes and the wall for the OSB board.
Made like a “box” over it all and made a hatch to reach the inspection lid.
Turned out great
Both the pipe from upstairs and the radiator pipes is suddenly gone.
