A small-scale honey farm with room for 12 beehives (36 total bees). Footprint is 5x8x5 with a 2x3 platform on the "front" for the spout depot. You should place the bees into the farm before building the cog array and tank on top, unless you enjoy suffering through fitting bees into tiny gaps. In theory, the bees cannot escape, though I cannot claim to have tested it rigorously.
