It covers up a main traffic artery, the Nord-Süd-Fahrt, and faces Europe's most frequented shopping mile, the Schildergasse. == Overview == With its unusual, organic shape reminiscent of a ship, but also of a stranded whale -- Kölners have dubbed it the Walfisch--it provides 14.400 m² floor space, on a length of 130 m and a width of 60 m. The atrium offers a view of five stories with a height of 36 m. The 4900 m² glass façade is constructed from 6800 individual panes and 66 massive laminated beams of Siberian larch. The northern façade consists of 4.400 m² of natural stone. Wedged between a late Gothic church, the Antoniterkirche, and nondescript post-war concrete, it consists of two distinct parts. A rectangular block of stone takes up the rhythms of the surrounding seventies' angular forms, while the partially encircling wood-and-glass construction flows toward the church that had looked somewhat displaced previously. Municipal regulations prevent the cupola from being accessible to the general public, but it is opened on special occasions. The department store is operated by the German chain Peek & Cloppenburg, which commissioned the Piano design, which has won several prizes. From P&C's point of view, this is one in a series of Weltstadthäuser, each designed by a different architect: in Berlin (Gottfried Böhm), Düsseldorf (Richard Meier), Frankfurt (RKW Rhode Kellermann Wawrowsky), Cologne (Renzo Piano), Leipzig (Moore Ruble Yudell), Mannheim (Richard Meier again), Stuttgart (Josef Paul Kleihues), Vienna (David Chipperfield, completed late 2011). == References == - [[Professional Practice/Codes & Standards/International Building Codes]] - [[Building Construction/Hill Architecture]] - [[Wiki-Architecture/Architectural Concepts and History]] - [[Professional Practice/Codes & Standards/National Building Code of India/Part 06 - Structural Design/Section 7B - Systems Building]] - [[Building Services]] - [[History and Theory/World History/Ancient Architecture]] - [[Structures]] - [[Environmental Design/Building Climatology]] - [[Interior Architecture]] - [[Professional Practice/Codes & Standards]] == External links == Media related to Weltstadthaus (Köln) at Wikimedia Commons Weltstadhaus Köln page on the P & C website (in German) Information on the facade structure on the website of the structural engineering firm Knippers Helbig Photos of the Weltstadthaus on Flickr
