How to create a second level in a room

[Vuemme43]

Hello, my room has two levels connected with an irregular step-form. How do I achieve this second level?

There are several ways of doing this. Depending on what you wish to achieve, some earlier threads may be of help:

4785 Room Elevation & Curved Boundaries (see hansmex' link with a nice example)
5507 Raised floor

Or is it something else you are after?
