After you put a few of these Outland models, you really don't need instructions, as the parts fit only one way. The material is such that light will generally not pass through as it might with other more traditional plastic allow, so lighting the interiors (4 floors max) . I also installed a "porch" light right above the door. These models are relatively easy to assemble (parts click together) and they offer great personalization in terms of lighting. You provide the window coverings, light, etc. The price is right too! I purchased about 10 of these models.
