t will not get simpler than that. The small hut is the simplest design possible. The walls are folded, so that they form an rectangle and the flap is glued. The roof is build following the standard
roof procedure.
Building the second, bigger house is just as straight forward, but has two added "difficulties".
First: There are two orange rectangles, that have to be cut out.
Second:
A step must be folded on the low wall as you can see in the picture to the left. The part folded is the regular striped pattern area (the floor so to say). The picture to the right shows what this is all about.
