Joel Spolsky has a post on his blog about his company's new office:
I can see that Joel is a fan of Peopleware with an office for each developer, which is not a popular choice these days with companies due to cost, but there is growing evidence that it increases productivity and, he argues, staff retention. Check out all of the photos, I would love to work here!
Updated 2021 : note that the above post is from 2009, but is left here for archival purposes. I had to remove the external link to the photos, as that is now dead.
