Aesthetics is in the eye of the beholder, and it depends upon the prevailing tastes of the time. A building's functionality, or fitness, is a matter of how well it accommodates the purposes for which it was built. Its structural integrity means soundness - will the building last over time? Historically speaking aesthetics has usually trumped fitness as the overriding factor in architectural design. Classical architecture was preoccupied with articulating features on walls and facades. Modern architecture is equally concerned with aesthetic formalities, such as form following function.
