How can psychology help design happy spaces?

And what this shows is the need the people have to express who they are, to express their identity. I think that once designers of offices become familiar with this need, they need to take this into account.

I think that this has implications on some of the trends in office designing. So, there is a lot of talk now about hot desks, when people come in and just take whatever desk is available and do their work their.
Sure, that may be quite efficient in getting people to do work and not take up much space, but in a sense, it neglects a very important psychological function of these spaces, which is about telling people who they are and conveying that to them.
