In the big universities in Berlin you have class rooms where everybody focusses (or is supposed to) on one topic, small side rooms for team meetings and project work, libraries for silent study (even sneezing is looked bad upon). That in my eyes is the best way for a big organization to provide rooms. People can choose one according to their current needs. If everybody is doing project work in a big hall that's aweful and pretty much nothing gets done. The best I found is working from home with people who are annoying chatters via skype/slack/IRC/jabber. Overspamming is a little necessary since you don't see each other face to face all the time. But if you have such people you can pretty much whenever you feel like it, sleep when you feel like, you don't need to wear trousers, and achieve a lot more than in a big office.
