I got into beekeeping inspired by my father, who has kept up to 30 colonies in a bee house for several decades, using so-called "Hinterbehandlungsbeuten" hives (Kuntzsch and DN formats for those interested).
I keep my bees naturally in horizontal top bar hives (KTBH) and vertical top bar hives (Warré). I've tried a couple of different hives, but settled with top bar hives now. This means foundationless comb drawing, no frames (just top bars), less to no treatments, more wax and non-centrifugal honey harvest.
My main guiding principle is to keep things as simple as possible and to let the bees do. They know best what to do. We can only learn from them. I tend to keep interventions (such as hive inspections) to a minimum.
