Right now we have building, which says If your question is about building techniques, this is the tag for you.
But we also have technique, which says Tricks and methods used to build models.
So right now, they're exactly the same thing - building techniques vs. techniques for building.
Which of these tags do we want to be the "right" one?
Or if we keep both, what's the difference between them? What's an example of a question that's about building but not technique, and one that's about technique but not building?
