So, nobody has a good plan for a doghouse for multiple dogs. I saw a plan I liked that has a house on a concrete slab. The house and exterior slab is covered in plexiglass so that the dogs have an inside area that is warm and an enclosed porch. These dogs will then have access to inside through a dog door, but I’m sure they will spend a lot of time outside as well and want something really nice for their outside hours. Another option is a straw bale house like DELTA rescue uses. Previously when I had dogs, the lab mix wanted to be outside more, especially at night, and the aussie wanted to be inside more, especially at night - absolutely opposite. I want these dogs go have the option of either, just as the old ones did. I already know that of the three, two will want to be in more, and one will want to be out more so I have to provide for both preferences.
