I’m available: Shutters and lower interior walls provide a means for easy and direct interaction among team members and coworkers. Perimeter walls define a group space; this boundary offers its own form of group control.
I’m not available: My Studio Environments gives people a means to discourage interruption by closing the door and shutters of the office; the translucent wall allows visitors and team members to see that a person is in the closed office, a clear signal not to interrupt.
