Elbphilharmonie: Hamburg’s dazzling, costly castle in the air

















        In Hamburg, Germany, Herzog & de Meuron just completed its version of a city in a box, the Elbphilharmonie, a mixed-use project featuring a major concert hall and recital chamber wrapped by condos and a hotel, with acres of parking below. The $880 million project, originally budgeted at about $80 million, took 13 years from conception to the opening of its public plaza on the eighth floor earlier this month. The first concert will be held in January.

Starting at a grand piazza in the middle of the building, just above the eight-story parking podium, an elaborate circulation system of stairs cascades through Piranesian spaces and distributes visitors up 18 floors. The architects posit, as Koolhaas implied, that civic life is possible in the heights and bowels of a building, even on upper floors. They urbanize the interior through the topography of a continuously terraced landscape: think the Spanish Steps climbing up a hill, though inside a building, with big programmatic elements—concert halls, restaurant, hotel and condos—attached.


Urban Architecture for Lovers of Culture
The new philharmonic is not just a site for music; it is a full-fledged residential and cultural complex. The concert hall, seating 2100, and the chamber music hall for 550 listeners are embedded in between luxury flats and a five-star hotel with built-in services such as restaurants, a health and fitness centre, conference facilities. Long a mute monument of the post-war era that occasionally hosted fringe events, the Kaispeicher A has now been transformed into a vibrant, international centre for music lovers, a magnet for both tourists and the business world. The Elbphilharmonie will become a landmark of the city of Hamburg and a beacon for all of Germany. It will vitalize the neighbourhood of the burgeoning HafenCity, ensuring that it is not merely a satellite of the venerable Hanseatic city but a new urban district in its own right.

The Archaic Kaispeicher
The Kaispeicher A, designed by Werner Kallmorgen, was constructed between 1963 and 1966 and used as a warehouse until close to the end of the last century. Originally built to bear the weight of thousands of heavy bags of cocoa beans, it now lends its solid construction to supporting the new Philharmonic. The structural potential and strength of the old building has been enlisted to bear the weight of the new mass resting on top of it.

Our interest in the warehouse lies not only in its unexploited structural potential but also in its architecture. The robust, almost aloof building provides a surprisingly ideal foundation for the new philharmonic hall. It seems to be part of the landscape and is not yet really part of the city, which has now finally pushed forward to this location. The harbour warehouses of the 19th century were designed to echo the vocabulary of the city’s historical façades: their windows, foundations, gables and various decorative elements are all in keeping with the architectural style of the time. Seen from the River Elbe, they were meant to blend in with the city’s skyline despite the fact that they were uninhabited storehouses that neither required nor invited the presence of light, air and sun.

But not the Kaispeicher A: it is a heavy, massive brick building like many other warehouses in the Hamburg harbour, but its archaic façades are abstract and aloof. The building’s regular grid of holes measuring 50 x 75 cm cannot be called windows; they are more structure than opening.

The New Glass Building
The new building has been extruded from the shape of the Kaispeicher; it is identical in ground plan with the brick block of the older building, above which it rises. However, at the top and bottom, the new structure takes a different tack from the quiet, plain shape of the warehouse below: the undulating sweep of the roof rises from the lower eastern end to its full height of 108 metres at the Kaispitze (the tip of the peninsula). The Elbphilharmonie is a landmark visible from afar, lending an entirely new vertical accent to the horizontal layout that characterises the city of Hamburg. There is a greater sense of space here in this new urban location, generated by the expanse of the water and the industrial scale of the seagoing vessels.



The glass façade, consisting in part of curved panels, some of them carved open, transforms the new building, perched on top of the old one, into a gigantic, iridescent crystal, whose appearance keeps changing as it catches the reflections of the sky, the water and the city.

The roof structure 
The 7,000-square metre roof of the Elbphilharmonie consists of eight spherical, concavely bent sections that form a uniquely elegant curving silhouette. In addition, 6,000 shimmering giant sequins have been applied to the roof. The roof structure, with its steep curves and high peaks, itself weighs 1,000 tonnes and covers the complex star-shaped steel framework that carries the Grand Hall without any supporting pillars. The roof of the Grand Hall is made up of a steel framework, each element measuring up to 25 metres in length and weighing up to 40 tonnes, the outer and inner shell, floors for the technical equipment, the White Skin with the reflector as well as additional loads. Altogether the roof weighs 8,000 tonnes. 



Elbphilharmonie

The bottom of the superstructure also has an expressive dynamic. Along its edges, the sky can be seen from the Plaza through vault-shaped openings, creating spectacular, theatrical views of both the River Elbe and downtown Hamburg. Further inside, deep vertical openings provide ever-changing visual relations between the Plaza and the foyers on different levels.
