can you explain a bit about your roof? it looks what we call in German “Kappendecke” but it appears here more like a style decision? a section would be great with layers of materials
My guess would be that the ceiling is a quote from Herzog & de Meuron’s new Hortus building in Basel. The floors are made in hybrid clay-timber system, which is actually as you pointed inspired by the old german Kappendecke (source: the structural engineer from that building during a open visit).
