The Easiest Way to Get an Elevated Room
Here’s the easiest way to get an elevated room:
Just build some supports and have an open level beneath it. Just don’t fully enclose the area beneath.
Elevated isn’t too bad once you get that trick down, although you’ll find you keep accidentally de-elevating the room (at least I do).
Now Isolated… that’s a trick. That I’m not sure is worth it.
