Sorry for that mistake... I had two files: Chambre & chambre...
Here is the correct file.

If you need more assistance, just ask. And if you provide a more detailed plan of your room (architectural drawing or SH3D file with exact position and size of doors, windows, wall height, etc) and tell me a bit of your preferences for colour and style, I can make a more detailed proposal.
