One of the most engaging showrooms at NeoCon 2013 this week is Buzzispace. Warm, inviting, with a strong sense of humor (and style), they are putting forward great examples of how you can pull off modern problem solving with good design.
The gentleman above is chatting on his cell inside a "BuzziHood" - an upholstered "phone booth" alternative that provides a spot to chat with some more privacy and quiet in busy open-plan spaces.
Here are more Buzzihoods mounted lower on the wall. Add a pouf or stool and you have a perfect small "office".
