Section of my first plan

I was decided not to have  the roof on as my first planning was to to have an open house and also Bamboo need space to grow up.
Those zigzag lines are a stair to go up to an extra space I add, Balcony, as I like have room that had a balcony. The reason of putting bamboo in the boat shed as it is represented to me, Nickname.
Also Pool, personally I love swimming and when I was youth I always had a dream that I will have a "swimming pool" in my bedroom.
