Multinational conglomerate 3M recently enlisted architects Atelier Hitoshi Abe, and Peter Ebner and Friends to re-design their St. Paul, Minnesota headquarters… and DesignBoom offers a look at the makeover.

In this photo set, we get a look at Atelier Hitoshi Abe’s conversion of the site’s central parking lot into a large pedestrian plaza with tangram patterned tiles, as well as the additions of collaborative work spaces with interactive touchscreens and public areas, such as the employee entrance and cafĂ©.

Additionally, the Japanese firm introduced two new stairways as a way to improve circulation between the different floors.
