That sounds like a lovely idea. We can start with a base of large, weathered bark sheets, pressed together with a layer of packed moss to keep the walls damp but breathable. Around the edges we can weave lichens into a natural insulation blanket—just let them grow on a thin bark strip and then carefully lift them. For the roof, a shallow ridge made of split cedar branches, weighted with stones from the riverbank, will let rain run off naturally. We might invite a friendly beetle colony to help aerate the interior: they’ll keep the humidity in check and add a touch of living mulch. And if we leave a small pit at the back for a compost heap, the insects will keep feeding on the scraps and our shelter will hum with life. It’s slow work, but every piece feels at home in the ecosystem. Let's gather the materials tomorrow and start building.
