Architectural utility is familiar as a Vitruvian concept but has a wholly other sense in an agent-centered normative ethics, with a possible moral weighting not found in classic architectural theory. Guidelines are needed to determine the usefulness of architectural goods such as built structures, restorations, reconstructions, or plans. These might include their social character, or individual preferences of the architect, owner, end-users, or public. A utilitarian approach to architectural ethics is attractive in capturing the aims of architecture to promote well-being, and relying on a ready marker of architectural value. However, it also discounts other traditional architectural imperatives such as a Vitruvian-style pluralist may honor, including beauty and structural integrity (Spector 2001).
