This paper presents the results of a qualitative investigation into the ethical and aesthetic values held by late- and mid-career landscape architects in the UK. It identifies the dominant discourses within three value areas, the aesthetic, the social and the environmental. Within the web of value discourses, some are clearly conflicting, while others are compatible or mutually supporting. The most prevalent values are those associated with 'technocentric accommodation'. A 'trivalent' approach to design is advocated which combines values from the three (...) main areas. (shrink)
