1st floor starting position is on the groudfloorwall

Hello,

Im looking for a way to let the walls of the 1st floor (or 2nd) start from above the floorhight.

for example: wallhight is 2500. then I put in the 1st floor with a thickness of 300. The walls on the 1st floor start on top of the walls of the groundfloor, not on top of my 1st floor wich would be 2800 hight.

I've tried with rooms and adjusting severall hights. But I can't seem to get my head around this.

The thickness of the floor points downwards, and the wall will start at this deepest point of the floor.
So, you have to build your walls 2500 in height, then add the floor with a thickness of 300 on a level which is at 2800. And then build the wall of this floor on a new level at 3100 with floor thickness 300, but with no floor on this level.
