I built 4 copies of the hive prototype, that I plan to populate in spring 2018 for testing. Results will be shared on this website. The complete hive is a intentionally small (25,7 L volume, including honey space). It consists basically of a fixed-frame hive body and one movable Huber leaf hive frame for honey harvest. It is managed from behind.
Have a look on the prototype hive (annotated exterior and interior views).
Basic operations (open, close, honey frame, queen excluder) are presented in the video below.
