Are the days of the open plan office drawing to a close?

Over the past 30-40 years the open plan office has been seen by management theorists as the route to optimal efficiency and interactive creativity.  The consequence was that in most towns and cities, fine grain plots with a diversity of architectural styles were replaced with large floor-plate monoliths.  And many would say that the character of towns has suffered in conseqeuence.  Research is now suggesting that the hot-desk, open plan office system can lead to a 30 pecent reduction in workers' well-being and a 15 percent drop in efficiency.
