I can't really tell, but it looks like the doors have obscured glass in the top half... I like that idea, since the majority of the daylight will come from the side that the door swings to (it's right next to the french doors that go out to the backyard).
Having a home office or message center in the kitchen can be extremely helpful. Here a floor-to-ceiling cabinet conceals a variety of office supplies and keeps everything organized and off the nearby kitchen counter. A five-cubby organizer built into side of the cabinets functions as a mini mailbox for each family member.
