How do you build a house not as small as a doll house, but big as a tree house?. Can you give me some specific instructions on how to start one? Such as what are the best materials to build the roof, walls, ground. By the way i want to put stairs in it to lead to a balcony. I know complicated but i want to build one.
Oh by the way, its going to be outside and i live in a country where we have four seasons.
