Apartment Building with Seasons Room,
Construction Site D29, Schönberg-Ost, Bern

The development for the site in the new Schönberg-Ost district of Berne was conceived by Esch Sintzel together with Rolf Mühlethaler and Graber Pulver Architekten. The underlying master plan by Hans Kollhoff is based on bourgeois residential quarters of the turn of the twentieth century, for instance the immediately adjacent Schosshaldenquartier.

The remits for the two apartment buildings by Esch Sintzel are entirely different: high-status and lavish versus radically reduced and cost-efficient. This resulted in the derivation of two fundamentally distinct typological concepts: a centripetal (aligned towards an inner middle) ground plan for the larger apartments, a centrifugal (moving away from the middle) one for the smaller apartments.

The bourgeois central living-hall served as a typographical model, directed towards an inner middle and therefore avoiding encounters with the immediate neighbours. In each apartment three loggias span the threshold spaces between the private and public worlds.

In contrast, the small apartments in the other building are trimmed to utmost efficiency. Instead of loggias there are large sliding windows at the corners. In order to create localized spaces for the rolling windows the exterior wall is offset outwards. By this means the motion of the window creates a motion in the surface of the facade, which becomes plastically structured solely through this spatial layering.
