I share your sentiment. I worked for a company that leased an old Sun building - all of the engineers got a private office. Three solid walls (unfortunately exterior windows were limited) and one entire wall was glass and frosted between knee and shoulder height. The door to the office was a floor-to-ceiling sliding door on this glass wall.
The offices all had whiteboards on two walls and were large enough to comfortably fit 3-4 chairs total. This was great because it meant any useful meeting could happen in anyone's office. There were larger conference rooms on the corner of each hallway which had screens for video conferencing and larger tables to accommodate larger groups of folks.
If you needed privacy to focus, you closed your door. If you were open to watercooler-chit-chat, you left your door open. It was easy to overhear technical conversations if you wanted to, but also easy to ignore since you had 3.5 walls of noise privacy.
At the time I did not realize how good of a work environment that was. It was almost a decade ago. I still consider that my ideal work environment if I have to work in an office.
