In partnership with The Cultural Landscape Foundation (TCLF), join us for a full day symposium, plenary keynote reception, and mobile workshops, exploring how landscape architects are reclaiming and redefining their relationship between research and design.
The Cornelia Hahn Oberlander International Landscape Architecture Prize, awarded by TCLF, was created to increase visibility, understanding, appreciation, and conversation about landscape architecture. The daylong conference on October 29 is inspired by the depth of research and analysis that informs the design work of Oberlander Prize laureate and Mexico City-based landscape architect Mario Schjetnan and his firm Grupo de Diseño Urbano (GDU).
At Longwood Gardens, the recent transformation and reconstruction of Roberto Burle Marx’s Cascade Garden by landscape architects Reed Hilderbrand and architects Weiss and Manfredi is a prime example of a holistic research-driven design process that values both natural/ecological and historic/cultural systems. Surveying the work and measuring the success at Longwood, and elsewhere in North America—the focus of this symposium and related events—provides the ideal opportunity to explore how today’s practitioners are building and sharing knowledge with the joint quest of revealing, honoring, and integrating cultural systems and lifeways in the face of inevitable change.
