Architecture is not a painting because it is three-dimensional. Architecture is not sculpture, because it is more than an object that you engage by walking around, at an imaginary perimeter. Akin to installation and experiential art if it was permanent, architecture is a space and a place that one moves through in time—maybe once, maybe over and over again.
Architecture is a journey and a work of art that exists to attract and serve. Architecture has beauty, has form, and has function.
