How To Build A Rabbit Hutch For The City Does Anyone Know How Much It Would Cost Aprox To Build A Double Rabbit Hutch?

Does anyone know how much it would cost aprox to build a double rabbit hutch? - how to build a rabbit hutch for the city

I intend, a maze of plywood, built like the one below, but I have no idea how the ongoing costs somebody has an idea, and how much cheaper, reclaimed wood from a mill? I have to build about 5 feet long and 6 high. Can anyone help?
