That wasn't really an open office. The usual open office is one open space for 50+ and sometimes hundreds of people. It's an awful place to work. There is usually a lot of distracting noise. What you described is something like I worked in. We had separate rooms for most teams(15 people or less). You could collaborate with fellow team members, which usually relevant for the whole team, but wasn't distracted by other teams. As you said it's the perfect balance of collaboration and privacy.
