What does a iriqou real longhouse look like?

The Iroquois longhouse was a building usually 60 - 100 feet long, sometimes much longer, 16-20 feet wide, and 15-16 feet high. It had a frame of saplings (young slender trees) and was covered with sheets of bark on the sides and top. It was occupied by a group of families; for every two families there would be a fire, usually spaced about 20 feet apart, with a hole in the roof above to let the smoke out. The hole could be covered with another piece of bark during rain or snow.
