I'm a huge fan of office "suites" - smallish offices which comfortably hold 3-6 people. It's a good sweet spot between open spaces full of dozens of people and individual offices. Usually suite-mates are people on the same team/projet as you, so you still get that open collaboration, but aren't distracted (or distract) the other people in the office whose daily work is unrelated to yours.
