The panels are assembled in this fashion and held in-place with some cleats and risers.

The following is an animation showing how they go together.

I was able to pick up 4 sheets of 1/2” x 49-1/4” x 74” spruce plywood from my local restore for $8 a sheet. From my estimates (if I don’t make a mistake) I have just enough to complete the house.

The 4 sheets will be cut exactly in half yielding me two sheets 24-9/16” wide and 74” long.

This is how I came up with the actual width of the panels used to make up the house.

In this case the bottom is framed with 2x8’s. A simple frame is created as shown here.

Note that 74” won’t span the length of the top or bottom panels, so I add two more cross pieces where the sheets are brought together.

The cut sheets attached to both sides of the panel with insulation in-between.

The bottom panel is put into place on the support structure.

This will be my new work bench for assembly of the rest of the panels.

Here I am working on the top panel.

Notice the two side panels in the foreground.

All four panels are complete. I give them all coat of exterior paint.

Getting the top panel in place needed some extra thought.

I first placed the top panel on top of the bottom panel and attached some straps. The top panel was raised and the two side panels slid into place.

With the top panel still held a couple inches above the side panels, they are slid into place.

I needed an extra inch of space between the side panels in order to get 5 12x3 hives into the house.

To do this I overhung the sides 1/2” of the ends of the bottom panel. I then added a 1/2” riser so that I would have a flush surface to attach the bottom cleats shown here.

With the sides secured, the top panel is lowered into place and the top cleats attached.

With the house in-place, everything was given another coat of paint.

Keep in mind that the actual house is not attached to the support structure and with effort, it can be moved. I will probably add a cleat of some sort to the front and rear.
