This paper argues that, as conflict, whether promoted, resolved or prevented, is part of the building process, it is properly subjected to ethical scrutiny within professional education. The nature of building itself, ethics and conflict are considered and questions posed arising from the assumptions made. The ethical aspects of the relation between conflict and trust and between conflict and co-operation are explored. Examples are given of how the ethical discussion of conflict can be related to the stories of building projects and to illuminating scenarios from general English literature. Questions for discussion are included in an Appendix.
