I thought this was an interesting article. I have worked in both open plan, and closed offices. Personally, I work quite well in both, but I do know of a few people who hate open plan (especially people who are introverted).
http://www.bbc.com/capital/story/201...g-our-memoriesNumerous companies have embraced the open office — about 70% of US offices are open concept — and by most accounts, very few have moved back into traditional spaces with offices and doors. But research that we’re 15% less productive, we have immense trouble concentrating and we’re twice as likely to get sick in open working spaces, has contributed to a growing backlash against open offices.
Maybe with all the excess office space in Alberta's downtown's, there will be a bit of a shift back now?
