The intimate area of the house is more visible than seen, through the gallery that on the upper floor skirts this atrium. To the left, overcoming a small gap, the notable dining room opens, overlooking the garden and, on the other side and facing the street, the billiard room. Beyond them, a wrought iron gate, designed by Edgar Brandt, separates from this social area the most intimate areas of the house: the upper floor, but also the library and service areas still on the ground floor.
