Generate a large steampunk airship,...

Generate a large steampunk airship, with wings on the sides. The ship should be made of wood, and the build as a whole should use no more than 7 block types. That's crucial. The ship should also have a spacious interior to allow for building. There should also be a ramp leading to the deck of the ship. The balloon should be white and bigger than the ship. Remember 7 block types AT MOST
