We propose to cross three disciplines, architecture, live sciences, and information sciences. Assuming that nature is a source of inspiration for architecture, we suppose that live strategies could be a model of adaptive architecture. Looking at the processes and strategies that plants have developed to adapt to their changing environment, we try to define the various components of adaptive architecture. We want to draw some parallels between plant, systems for information processing and how adaptive architecture is working. Our problematic is composed by two main questions: The first question is: What is adaptive architecture? The second question is: How plant signalling could be a model? The goal is to design a more efficient architecture in the context of environment and uses changing.
