In an interesting article appearing in feep.com linked on twitter by SteelCase the work environment at The United Way of Southeastern Michigan is described in detail. They made a move from a 12 story small footprint building with dedicated offices and desks, to a 2 story facility with open cafe like desk environments and limited fixed desks for a narrow segment of their positions. This allowed them to greatly reduce the size of their office space, maintenance and utility costs. Hot Desking or Hoteling is the way this is often described, and it is facilitated by a telephone system that routes calls to wireless phones or individuals cell phones. An interesting execution of a non-territorial office environment.
