Yeah… Pretty disappointing read. Sounds like they built several prototypes before they bothered looking into what the requirements were. They are basically building a very complex top bar hive, the same kind that you can slap together with the materials from a single pallet board (maybe two if you have cheap ones without many supports). There are tons of plans online including deep dives into the “why” of each of the dimensions. For anyone who is interested in keeping bees I would highly recommend you go read up on these hives from someone who has kept 100+ of them; I really enjoyed his naturalistic bee-centric approach. http://www.amazon.com/Top-Bar-Beekeeping-Organic-Practices-Honeybee/dp/1603584617/ref=sr_1_1?ie=UTF8&qid=1394506375&sr=8-1&keywords=top+bar+hive
