Mmh, I’m casually watching the videos of Werner David. It’s a bit sobering. I haven’t seen or read everything yet but I have the impression that the hotel is really only worthwhile for bees. Lacewings don’t care about a "home". For them, only food in the form of aphids counts. Beetles, centipedes, ants, and other crawlers prefer dead wood or stones. So everything that just rots away on the ground – ok, I can pile that around. That leaves ladybugs or butterflies – I haven’t read any information about those yet.
For the bees, it would also be important to be able to change the tubes regularly, otherwise there is a permanent risk of mites. So you should be able to put the wooden blocks in the oven once a year or simply use cardboard tubes that are then destroyed. That’s why oven-friendly sizes are produced.
So for the bees there are 2 floors and the entire ground floor is "decorated" with dead wood and stones. There is a water source in the form of an old wine barrel next door. It stands directly on the cistern, where a hand pump with a lever is supposed to go. The whole thing is framed by the nutrient-poor meadow, which hopefully then brings enough flowering plants.
Well, and what do I put in the remaining 2 floors? I’m still a bit clueless. ops:
