ATLANTA—According to globalworkplaceanalytics.com, 3.7 million employees work from home at least half the time. Although that's just under 3% of the workforce, consider a statistic that puts the trend in context: The employee population as a whole grew by 1.9% from 2013 to 2014, while the telecommuter population grew 5.6%.

That has led to a decline in the average in-office workspace in recent years. Global Workplace Analytics reports the average space per worker ranges between 130 and 150 square feet. That's down from 200 square feet. The bottom line: Employers are moving more workers into smaller spaces. Put another way, there's a decreasing demand for traditional office space and a move toward creative office solutions that doesn't seem to be slowing.

“Employers are increasingly offering their staff flexible work arrangements and options to work remotely, so it naturally begs the question of how much physical office space is still needed,” Fred Schmidt, president and COO of Coldwell Banker Commercial Affiliates, tells GlobeSt.com. “Employers will always need a space to hold meetings and bring staff together, so we do not foresee a decreased demand for office or creative spaces, though it is a trend that will likely impact office layouts in years to come.”
