Although I don't like the wall of glass he chose. I'd sacrifice some light, to not be distracted by people walking by all the time.
In building some of the V2 houses we figured out that having a door (that you tend to leave open all the time) directly behind you wasn't a great thing. The new ones have the door offset to one side so there's no "over my shoulder" feeling and it feels more private. To get light we have three much larger windows now, an opening at each end on the roof line and two skylights in each.

It was a fairly open office, so there was /some/ natural light. Not much, but some. The office used pretty bright/natural-looking lighting anyway - it wasn't flickery, dim, or harsh. We hardly got distracted, because we covered almost every inch of the glass with whiteboard marker diagrams, notes, et cetera. One of my officemates used the window behind him as his todo list.
It was by far the best office situation I've been in in the past five years.
