Natural materials can be the basis of industries designed for long-term economic growth instead of short-term extraction. This "nature-based industrialisation" fits building production to each ecological habitat, so that the economy and the environment are sustained together.
Old building traditions are useful as a starting point to adapt, not as a template to repeat. The goal is a change in style that carries the old logic forward into new conditions: "not a repetition of the past, but an evolution."
A sustainable building comes from working with the land it sits on and with the people who live there, not by imposing a design from outside. This means keeping craft skills and local know-how alive, because they hold solutions that would otherwise be lost.
