I'm very assertive when it comes to organizing, so here it goes (especially for people who landed here from other websites...)
If we had a separate office I would've done it little differently with less boxes. However, this is where we pay bills, read and play computers, not to "study" or "work" so stacked boxes don't bother us, and I'm certainly not gonna spend $30 or more for Expedit drawers because I consider living in this apartment a temporary and do not want to spend too much money for something I might or might not use if we get to "own" our place in the future. I know I'll use the boxes no matter where I go.
The boxes on top mostly hold statements, important documents we don't need to access every day. They are all labeled so if my hubby needs a car insurance statement he can go right into "auto" box. I go through those boxes a couple of times a year to shred old papers to make room for new papers so I never run out of room.
Because we live in a small space, editing is critical. If I see something overflowing on this shelf I edit and then add. If we have kids in the future and need more books and toys I'll re-structure the whole thing.
Also if you look at the pictures of our entire apartment you can see how neutral it is. I love neutral palette and I don't really like "splash" of color. I especially keep this bookcase very neutral because it's right in the dining room I wanted it to blend in with our white walls to look like a built-in. I also try to use natural materials for storage if they can be seen but I use lots of clear plastic boxes for storage in the closets etc.
Bottom line, this bookcase serves us very very well.
