I am aware about the nature/well-being (I even read a study regarding sports performance), but I have no knowledge on the findings on how to organize work floors. Care to share some links? Thanks.
After that, read the Malcolm Gladwell article how her findings can be applied to office culture. http://www.gladwell.com/2000/2000_12_11_a_working.html
After all that, apply all that to offices you've seen.
