How to create walls, floors, ceiling in 3d?

Hi. I’m trying to make a scenario from scratch, I want to make a hallway in a house (for reference, it can be a hallway in a house like the one in SilentHill PT). I have 3ds MAX and Blender but I have not gotten an updated tutorial where they teach me how to create walls, floors, ceilings, etc … I have followed some but when placing the walls in my unreal engine project I notice strange lighting. I wish someone with experience could guide me.

Better look for tutorials on youtube.
