Well I just tried to reply but must have messed it up.
Some of mine stay in the house fulltime so this is their shelter and then have crates when we are gone, pet mates and pet taxis and one big wire crate.
The ones that are outside have dog houses this is what they look like.

They are custom built and cost about $180 in materials. They are isulated and very warm in the winter, they have metal around them so the dogs can't chew them up and eat them into nothing, the top can hinge open to clean out bedding, it has a little porch they like to lay on (some like to jump ontop too), but they are extremely heavy to move, it takes 2 people to move them, first you have to get them on the wagon and then move them where you need them.
