level 1 The piano shaped opening takes over a significant role on level 1. It is built up as a shelving. To the north it defines the space between facade and opening, while the shelving continues beyond the opening it emphasizes the linearity of the long windows. To the south it determines and directs the movement. On the one hand it mediates between the living room and the terrace and on the other hand the opening directs the change of the staircases. In addition it works as a visual link between the first two levels. Thru the change of the staircase, the service staircase changes from a semipublic to a private space. Whereas level 1 is accessable in three different ways, the upper levels are only connected by one staircase.
A curved screen encloses the dining area which is next to the kitchen. The screen projects itself into the living area. Its shape is similar to the staircase sculpture of the ground level. The screens and the piano shaped opening together with the staircase of the entrance hall form an sculptural ensemble. In level 1 they enclose the living area, which is centrally located with a view towards the garden.
