On the general discussion of open vs closed work space: IMO there are four types of mutually exclusive workspaces in a tech office setting: Open collaboration, library time, telephone booths, and small to large general assembly. These four, while briefly explained, highlight their purpose for optimal productivity in the day to day workflow. Specifically, library time would be an open space for work but with an implied quiet noise level. In contrast open collaboration is similar but without the noise level restriction. Both spaces would live in separate areas not near each other for understood respect in work style. Just my 2 cents. :-)
