Gigon Guyer - Switzerland Platform Office Building Maagplatz 1, Zürich 2007 - 2011 |
In
the immediate vicinity of Hardbrücke railway station, the seven-story
office building called Platform completes the ensemble comprising the
high-rise Prime Tower and its annexes Cubus and Diagonal. The
building’s volume, with various angles, reacts to the urban situation,
providing a coherent link between the station and the new central
square. A two-story-high passage through the building connects the
square with the public pedestrian and bicycle path along the side of
the tracks as well as with the new pedestrian underpass to Hardbrücke
Station. In addition, the passage acts as a generous covered area
outside the entrance foyer.
With its pronounced horizontal and layered design, the building contrasts with the Prime Tower nearby, effectively forming its reclining counterpart. As in the tower, the stories increase their floor area as the building rises, made possible by various projections. the volume of the building is also subdivided by courtyards that cut into the west and south sides and ensure well-lit office spaces within, as well as by the angular projections in the façade. The central, prestigious entrance foyer forms an additional internal open area. A tall atrium flooded with natural light links the entrance level with the office floors above. Its function as a hub that lends the building its identity is additionally underlined by the open staircases and adjoining seating areas on the office floors. Dark glass balustrades mirror the space and the light in multifaceted reflections, creating a kaleidoscope effect. Next to the entrance foyer on the ground floor are a restaurant, a cafeteria, and an auditorium. A wide, inviting staircase leads from the entrance level to the customer lobby on the first floor, from which the various conference rooms can be accessed. the levels above provide office space for around 1,000 staff. Although the building has been conceived as a corporate headquarters, the positioning of core facility areas permits a variety of office typologies if required in the future, including the division of each floor into a maximum of four separate rental units. Wall and ceiling paintings by Nic Hess, wallpaper and drapes by Lachmayer/Nobis and a textile sculpture by Ernesto Neto complete the interior. To be able to meet changing spatial needs or different uses without radical structural alterations, the building has been designed as a load-bearing skeleton structure with reinforced cores. The glazed façade is articulated by horizontally layered bands of parapets and windows. The double windows hold sunblinds in between and help reduce noise from outside. The inner windows can be opened for ventilation purposes toward the interim space of the double-skin façade. The slightly reflective outer glazing shell and parapets accentuate the building’s folded structure.

Eine doppelgeschossige Passage durch das Gebäude bildet den Eingangsbereich und verbindet den neuen Platz mit einem weiteren Zugang zum Bahnhof. Mittels Gebäudevorsprüngen auf unterschiedlichen Niveaus nimmt die Geschossfläche mit zunehmender Höhe zu. Hofeinschnitte und variierende Volumenknicke, ergeben optimal belichtete Büroflächen im Inneren und gliedern das Volumen. Ein hohes, lichtdurchflutetes Atrium bildet das identitätsstiftendes Zentrum des Gebäudes und verbindet das Eingangsgeschoss mit den darüber liegenden Büroebenen. Von hier aus werden im Erdgeschoss das Restaurant und ein Auditorium erschlossen. Eine einladende Treppe führt in den Kundenbereich im ersten Obergeschoss und von dort weiter in die Bürogeschosse. Die Glasfassade besteht aus horizontal gegliederten Brüstungs- und Fensterbändern. Letztere bestehen aus zwei Verglasungen, in deren hinterlüftetem Zwischenraum sich der Sonnenschutz befindet. Durch das äussere Glas bestmöglich vor Schall geschützt, lassen sich die inneren Fenster individuell öffnen. (Text: Gigon Guyer) |
