Further, architectural appreciation is environmental in building on our understanding of architectural objects based on experiences in relation to their natural and built surroundings.  On one view, an architectural object may be more difficult to appreciate if we find that relation unexpected, or contrary to normative sensibility (Carlson 1999). If, however, appreciation does not require enjoyment or satisfaction of any sort—and instead engages our understanding of, for example, what was intended and why—we may well appreciate in its own right an architectural object that has a surprising, even obnoxious relation to its surroundings.
