Landscape architectural design practice is explored through the relationship between current landscape construction approaches and the evolving contemporary environment.In particular a framework for landscape design based on techne-an ancient Greek term broadly meaning craft, craftsmanship, art or the rational knowledge inherent in making is introduced into the landscape field.Techne acknowledges workability and the durable ecological, economic, cultural and environmental dimensions within the implementation of built landscape work and can offer an alternative landscape focus to the design concems of indeterminacy, openness and flux currently advanced by academics and practitioners.Opportunities and challenges are outlined and discussed through the recent practicum work of the Center for Technology and Environment (CTE) at Harvard University Graduate School of Design founded and led by the author.In particular the potential of new site technologies, an emerging range of landscape materials and the nature of regeneration engineering are delineated through site design case studies located in Europe, Africa and the Middle East.
