Open-plan offices are pretty much the standard approach these days, but that doesn't mean they work for everyone. When Australian software developers Campaign Monitor moved to new premises, having closed offices for each team member was a key requirement, but the end result is anything but stodgy.
Campaign Monitor's Sydney premises house 40 private offices for serious work, but also include key spaces for relaxing such as kitchens, gaming and ping pong areas. It's quite reminiscent of Google's Australian HQ, but it has to be said no-one at Google gets a private office.
