Right, but even if the percentage of such a person is 50%, then you are only catering to half the crowd.
I realize giving an office to everyone is not the best (or the most realistic) solution, but I think a compromise can be found, some parts of our office have these large cubes where 2 to 4 people can sit, this keeps you together with your team and makes for easy interaction/collaboration, but at the same time the high walls surrounding you keep the background auditory and visual distractions to a minimum, this way there is something for both the groups of people.
