SERENDIPITY SANDWICH
This sandwich is based on the commercial success of shopping malls. You'll make sure people pass by all the shops by placing what is lowest in the Maslow Pyramid (which is the food court) at end of the mall. At the office building, most people will be using working stations and will go for lunch at the canteen. By placing the occasionally used spaces in between the working stations and the canteen you'll make sure occasional users pass by the desk workers or they will see them in the canteen, increasing the probability people meet.
A chat at the coffee corner can take place in any office. But what are people going to talk about when they don't know what people are working on? The main hallways of the office building become exhibitions where every 3 months teams exhibit visually what they are working on. This makes it more likely people who meet at the coffee corner have a conversation about each others competences instead of a chat you could have also anywhere else outside of the office building.
