This is a "hive bank" I built based on M Palmer's writing and D Coates nuc dimesions. The box is about 8' long, and holds 10, 5 frame hives. The base box is built from 2x12 with 2x12 dividers between each 5 frame unit. The top boxes are 5 frame deeps. I use 3/8" plywood for inner covers and a 2 piece outer cover that allows one side of the unit to have more supers than the other side. The placement of the inner covers determines how much space a particular hive uses. Each hive has a 1" entrance hole at the bottom and a 1" vent hole near the top of the uppermost super.
I have 6 of these units in operation right now. The first picture shows a 10 hive bank with 10 frames each (5 over 5). The lower picture shows 3 units totaling 30 hives. Note 2 of the units have 2 supers on one half the hive bank.
