My parents converted their attached garage a couple of years ago, but they've never truly finished it (runs in the family, I guess). It was originally envisioned as a master suite, then a family room (it's right off of the kitchen), was used as my grandmother's apartment for a while, and has now become a catch-all room that no one uses. It's sad really, because it's a huge space. So I'm trying to help my mom de-clutter, re-organize, and re-purpose the room.
Since it is such a large space and there is a structural beam running down the middle, I love the idea of using barn doors to create a flexible space. Here are some inspirational pictures I've found online.

The above would probably work best - because (since it was a garage) there aren't a lot of windows and this would let in a lot of light, even when closed.
