Concrete staircase covered with oak treads and risers, natural finish. To hide the gaps left between the wall and the treads, cover strips were fitted both on the inside and on the outside of the staircase. The railing was fitted on a wooden rail so that an equal distance could be kept between the intermediate balusters on the sloped part, and on the straight part so that the parquet could be laid easily. Because the upper railing was long, an intermediate newel post was added.
