The narrow lot is developed with maximum cubature and utilization: on the very top, the living space with a view of the Rhine valley and the Drei Schwestern mountain range. The sleeping quarters are retracted, cross-shaped reduced to the private spaces.
The ground floor, open, resting on pillars, is entrance, terrace, and garden in one. Far below the ground is the wine cellar. All floors have a different ground plan. The stairway, a double helix, distinguishes for guests, the accessible spaces from the private ones.
