Since we decided to fill up the part of the cellar that was in disrepair, we had to fill the door leading to that part of the cellar with concrete filling. We started with the bottom part of the door. We will not fill the window next to the door. It will later become part of the riser. In the second part of the cellar, which is usable, we plan to establish a technical room. Pipes from the technical room will pass through this riser up to the production rooms.
