Herdern Railway Service in Zúrich

EM2N Architekten 

The sheer dimensions of this hangar located in the railway hub of Zurich-Herdern will allow the maintenance of intercity trains of the Swiss train network. It rises two floor heights and stretches 400 meters.

The function of the railway facility determines its regular and compact volumetric composition. It is formed by the extrusion of a rectangular section homogeneously illuminated by skylights that have been integrated in the roof, and built with structural frames of steel arranged in regular intervals, in the process generating a serialized geometrical scheme. Placed over this scheme is a grayish, bold, almost hermetic envelope broken longitudinally only by a continuous horizontal slit set close to the ground, and constructed with dry-joint cladding panels.

Molded with an organic and three-dimensional, bulging pattern, these modules are prefabricated pieces of reinforced concrete further strengthened with fiberglass. Starting four meters up the facade, the bulge of the pillowed panels progressively increases, all the way to the top of the building, causing a disturbing feeling that the outer wall is about to collapse.

The panels, each with a thickness of 15 meters, are supported by wooden furring strips in a structure of steel profiles with 140-millimeter sections. The extrados has been completed with a sealing agent and a thermal insulation layer of mineral wool whose thickness ranges between 60 and 140 millimeters, all finished in the interior with a cladding of sheet metal.
