My old company did the opposite of this. As they expanded, they built worse and worse office environments. I started out in a nice 10x10 cube, and ended up in a 5x5 low-walled cube, on an 'expansion floor'. After I quit, the primary building tenant moved to a new building, and the company I had had worked for became primary. This auspicious event was marked by the building cafeteria (fairly decent as these things go) shutting down, so not even hot food was available. So yeah, not all companies get better digs as they expand.
