Might as well start a collection of resources about compact vertical hives.
Here is a very good PDF.
Some google translation will be needed.
Very good photos contain lots of detail just as is.
The author of the PDF is located at about USDA zone 4 - this is where he runs the said hives (in Russia).
A quick quote of page 14.
I really like the frame ideas - look at page 20 and page 22.Boxes consist of sandwiched plywood (inside), foam insulation - 3cm, plastic outside.
Each body is for 9 frames with one round entrance.
Frame size - 300mm x 230mm.
Roof telescoping, insulated with foam; bottom depth 8-9 cm with front entrance slot and rear access.
A hive set: 5 bodies, two bottoms, two roofs (to support the hive splitting).
