The article cites research from North Carolina University, Gensler and Quartz, showing that the most productive offices balance both open floors and enclosed space, private for working. Quartz breaks down the ways in which open-offices torture those workers. The takeaway: drawbacks are serious, and include distraction, noise and more sick days than other configurations.
The article reminds me of the real estate implications of Susan Cain's breakaway bestseller Quiet: The Power of Introverts in a World That Can't Stop Talking. Cain's phenomenally well-researched work concludes that both introverts and extroverts need physical work spaces that brings out the best in them - including a robust chapter on how collaboration can unexpectedly kill creativity. If you haven't already poured through this - highly recommend the book for a fascinating perspective, with implications for communication, recruiting, management, and interior design.
