We are facing how to work on large-scale landscape changes and identify how to act. This has been my question these last years. I answer quick and in a simple way even if the topics are very complexes. It can look as an oxymoron situation to act fast on those landscape transformations. My mode of practice is by X- Raying the existing site, bringing up as an Echo or highlight the immanence of the context as main identity of a site. The programme enlighten the under-frame, the design gives form to the landscape dynamics that I can read. The dialogue between under-frame and frame of the landscape are transferred as metaphor in my way of acting in other workspaces.
