When we visited the construction site, we wondered how could we make a large spacious family house in just 32㎡, considering also that the staircase would probably have taken a significant portion of that area. So we got the idea to make the stairs as a hole in the centre of the house, while the floor area, like services and rooms, have been set in circle all around.
