The article discusses the completion of the Winthrop Center, a mixed-use tower in Boston that is now the tallest in the downtown core. The building is notable for its green credentials, including its achievement of Passive House certification, making it the world's largest Passive House office building.

The article also highlights the building's other attractive features, such as flexible office layouts, shared amenities, and a ground-floor space for public activities.
