Open plan is a terrible idea. Everybody is on headphones all the time. Nobody has privacy or a sense of personal place. People defend it as a consequence of working remotely. I think it actually makes working remotely more attractive.
Patrick, great point. I have done some research over the years. A useful place to start is the relationships between people and natural behaviors. Also under all circumstances avoid the “no one has a desk anymore” vagabond office extreme. This is profoundly flawed.
