This time, we will create a floor that is one step higher than the floor on the second floor, a skip floor. Normally, a skip floor is created on the landing between the 1st and 2nd floors, but this time it is different. Since the bottom and top are open spaces, we will process the handrail to prevent it from falling and create a shared space that can be used by the whole family! The finish is to pull the tatami mat down.
