If I'm coming into the office, I'd rather be around other people than locked in my own room (otherwise I might as well be working from home), so I prefer small open-plan offices - maybe 3-8 people in a room. More than that starts becoming too loud and distracting, but fewer than that feels too isolating. This all needs to be done properly, i.e. no meetings or phone calls in the open space, an expectation that you don't just constantly interrupt people you're working with, spaces available for quieter or paired work, etc, but if it is done well, I much prefer that to cubicles or private offices.
