No. It is really another small garden house at the end of the terrain

Hello, I am new in this software. I made a leveled terrain (2% slope). I have separated parts on my terrain. For the large part, the house, everything is ok, the floor is on the terrain. But when drawing the walls of the second part of the property which is on the lower terrain, my walls are floating in the sky, approximately 20cm because the 0 level is on the main house. How can I create a new 0 level for the second part of the estate? Thank you
