Bedroom wing on raised level

[Havouza]

Hi!
We live in a L-shaped bungalow. The bedromms are in the "foot" of the L. Thisa part is 0.5 m above the rest of the house. The outer walls are all of the same hight so the hight between the floor and the celing is 0.5 m lower in this part. Is there a way I can contruct this in the program?
Hope someone can understand what I mean

You could create two levels, and set the height of the second level 0.5 m less high than the height of the ground level.
Reading this tip should help you too.
