If you screw a bookshelf to the wall, does that make it a “Built In”?

While “fastened to the structure” is one of the definitions of a Built In (or, Builtin), most of us expect a built-in cabinet to do and be much more than that.

I've been creating a series of videos on built ins . If you have any interest in built ins, you'll want to look at them soon and make comments (I'll make it worth your while). They will only be available there for a limited time.
