Value negotiation and professional self-regulation – Environmental concern in the design of the built environment

Built environment design professionals balance competing requirements for human comfort, aesthetics and ecological integrity in their projects. Among them, landscape designers play an important role in optimising the benefits derived from urban green spaces. This study critically considers value dimensions and domains that impinge on professionals’ decision making and environmental values that are applicable to built environment design. It specifically identifies the dominant group-based value domains and environmental values in local practice and examines how landscape designers determine the relative importance of competing values in urban South Africa. The study made use of semi-structured interviews with long-standing figures in the industry. The findings indicate that the political change, the economy and the varied climate and landscape character are contextual influences that strongly shape regional social constructions of urban nature. These constructions emphasise instrumental utility values that juxtapose fundamental values and overshadow less urgent eudemonistic and intrinsic environmental values. In the design process, designers trade off artistic pursuits for utility values, with implications for aesthetics and quality. The contextual influences undermine value pluralism. Current trade-offs arguably perpetuate a local legacy of the uneven distribution of quality green spaces. Promisingly, designers show environmental concern and value for sustainability , indigenous plants, utility, quality and safety. The potential for designers to strengthen bonds with urban nature lies in the creation of aesthetic experiences that build on existing local affinities to landscape character and indigenous species. Professional bodies have an important task to assist built environment designers in creating cities that preserve human-nature relationships. • Contextual influences strongly shape landscape design values in the Global South. • These influences undermine value pluralism. • There is an over-emphasis on instrumental utility values. • Unique local environmental values are identified. • Environmental care is illustrated as emergent from social-ecological relations.
