third workplace

(名詞) 第三個工作場所 - 一個人除了公司辦公室或自家辦公室以外的工作場所。

There is plenty of talk in alternative workspace circles about the third workplace. In other words, places [sic] to work beyond the office and the homefront.
—Jennifer LeClaire, "Do You Really Need a Third Workplace?," A Better Office, November 21, 2013

The third workplace, commonly called co-working space, combines the amenities and technology of a traditional office with the flexibility and lower expense of a home office.
