Yes, if you looked, these videos ARE for The Sims 3.
You can't normally place foundation inside the walls of a ground-level house, but you can do something similar with some work. It's the only way to make a ground-level area and a raised area in the same room that looks any good. I don't think you can make a raised, island-like deck area in the middle of a room if that's what you're asking though.
