Art is so elusive, so highly abstract and beyond what is perceptible from senses. It is usually compared with music and literature. Talking about architecture, it is more used with some utilitarian purpose and of course with the desire to please. It is mostly precepted by the senses, but if we say that art is connected to beauty and ugliness we are wrong. Art is a measurable phenomenon. One important part of it is the form, which is common to all works. There are a lot of examples like Crace, Greek people, Golden Section, distortion etc., that tried to define it, but to sum up we cannot find a real definition about it, just as an attempt to create pleasing forms.
