I agree with this one. In my old company we used to be fully open planned (all departments could see and hear each other). We moved offices and split into different departments, this meant we could talk more openly and helped create functional, solid teams. It also stopped other departments getting annoyed with our technical debates over x and y. It also helped us talk in private when necessary about issues. An example being that we had a bunch of redundancies after the office move and it wasn't appropriate to talk about them in a public area. You'll be surprised how talking about it actually helps in morale, as it gives a mentality of "we are all in it together". I was working at an established SMB with about 40 employees.
