You can build The Garden Coop on a slope fairly easily because the frame of the chicken coop rests on piers. As long as your piers are tall enough on the lower end of the slope, you can use those to compensate for the height difference and keep the frame level. I recommend 16″ (400 mm) cinderblocks positioned vertically for this purpose. Our coop plans describe this in greater detail.
You also want to make sure that the hardware cloth is long enough to still be buried on all sides of the chicken coop by a foot or more. This is part of the process of making sure your chicken coop is predator proof and secure from tunneling critters. Again, our coop plans describe how to do this. If your slope is drastic, you can add some framing on the low end below the basic frame to help attach the hardware cloth to.
Above is a picture of a Garden Coop that Christine S. and her son built on a slight slope in their backyard near Seattle. The photo is a little grainy but should give you an idea of how to use the piers to keep the frame level. The picture below is of their finished chicken coop, wrapped with hardware cloth and chicken wire.
