I have understood that ecological construction is important to you and that you have a pretty good idea of how you want to live and orient yourself by "how people live". I see parallels to us and our project in that. We visited all kinds of providers, looked at log houses, spoke with architects. One was good at listening and we felt understood. He received a jumble of pictures and examples that we collected, each with a comment on what we liked about them. We knew that all these aspects would not fit into one house. Then we had a design made. Very much requiring explanation, but we understood it and it felt right. With few changes, it is now being built with local companies. Try to find an architect this way. Interestingly, our house would approximately meet your requirements including [Praxis]. However, the terrain conditions are different. More gladly if interested via PN
