Options>Project Preferences> Working Units> Reference Planes.
Here you can enter the courtyard and the Garage as the 2 other reference planes.
Each time you insert an element such as a wall, piece of furniture etc. you choose the elevation and to which reference plane it is being inserted.
The cutting plane for any floor or ceiling view cannot be staggered. You will still cut through the walls of each of these three spaces at the same elevation height.
You can get the correct plan look by choosing the correct setting such as symbolic or projected etc for the walls and/or each element.
This has been discussed here quite often, so you might do a search for additional views and more detailed explanations.
