Architecture has always been found in a space between its economic and cultural values. As distinct from the intrinsic values attributed to the visual and performing arts, literature and music, architecture's values are often seen to be compromised by, or contingent upon, forces outside of the discipline—on property prices, real estate markets and the vicissitudes of local and global economies. Such intersections of cultural and economic values are especially conspicuous in architectural heritage where conflicts between values are most publicly and passionately contested.
