Level scenes Workflow

Here is some  breakdown from the bathroom on how my usual progress is when creating scenes for this environment.
I start with the room blockout from the whitebox, do some more detailed blockout with primitives for what props and assets i need for this scene.
I then proceed with a material pass for the modular parts, walls, floor and roof. I then add extra details here such as the tiled wall material added in the third image.
I then create the major assets that is needed for this scene, in this case a toilet, bath tub and sink.
After this i create placeholding lighting and sstart to add details and mood to this room.
I now can add extra assets such as more generic house items such as radiator and light switches, debrish and details to finalize the scene and then complete the lighting, bake the lighting and add some post process and effects for atmosphere.
