The Elbphilharmonie, a concert hall in Hamburg encased in glass and set upon a giant brick warehouse, is surrounded on three sides by the waters of the city's bustling harbor. Designed by the Swiss architecture firm Herzog and de Meuron, the building cost about $850 million, took more than a decade to design and build, and was for a long time cited as a joke - a dark joke - among Germans who fretted that the project had become an albatross: unbuildable, over budget, and wildly out of proportion to what the sensible people of this mercantile city wanted or needed.

But the building, one of several projects around the world which aim self-consciously for "iconic" status and have price tags in the billion-dollar range, opened to international acclaim on Jan 11. The acoustics, designed by the renowned Japanese acoustician Yasuhisa Toyota, are a marvel of clarity, precision and cool objectivity. Visitors enjoy stunning views of the industrial grit of Hamburg, renewing the city's relation to the source of its wealth and its cultural window on the larger world. Tourists flock to ascend the Elphie's long escalator, rising through the old warehouse in a tunnel of white glass and plaster to visit the rooftop terrace, which bustles with activity before and long after evening concerts. If you want to attend a concert, good luck, because almost everything is sold out.

"Demand is overwhelming," says Christoph Lieben-Seutter, general director of the Elbphilharmonie. Subscriptions for classical concerts have doubled since the hall opened, tour operators are pressuring the organization to make more tickets available, and more than 1.5 million people have visited the public plaza since it opened last November. The building has become a phenomenon throughout the country. "Music isn't just the talk of the town, it is the talk of Germany," Lieben-Seutter says.

In March, the Caracas-based Simon Bolivar Symphony Orchestra played all nine Beethoven symphonies at the new hall. At the end of the third movement from Symphony No. 5, where the first violins seem to get stuck dithering a scattered reminiscence of the main theme, there is one of the most famous crescendos in the history of music, a swelling and triumphant transition from darkness to light. The sound in the hall was so accurate that if you closed your eyes, you could point to exactly the spot where the timpani player was gently thumping his drums, and as the winds joined the strings, each addition to the burgeoning chord was like another color being added to the spectrum, until the light was brilliant and white.

Those eight bars could stand for the astonishing shift in public perceptions about the building, "from a scandal to a world wonder," as Lieben-Seutter puts it. Two decades after a Frank Gehry-designed outpost of the Guggenheim Museum opened in Bilbao, Spain, the idea that a building can transform a city, or a cultural institution, isn't held in high repute anymore. Debt and disillusion have made the "Bilbao effect" seem a hollow promise of a different age.

Here it is, back again, and it's imperative to know why it is working. Why this building? What about its design, its location and the implicit social messages embedded in its architecture have made it so successful? Carsten Brosda, a senator in Hamburg's state government and head of its cultural authority, says location is a primary factor in its success. "I was never a fan of iconic buildings because so many of them are rather generic," he says. But Elbphilharmonie is exceptional, located in the geographical heart of the city, on a site that demanded some exceptional public use. "There were architects saying this is on the verge of being unbuildable, but that is what makes it unique."

But it is the architecture, the way it floats like a giant ship above the old brick factory, the drama of how one enters and moves through its spaces, and the way it situates people in relation to each other in the soaring auditorium, that makes this building truly extraordinary. The shape of the building was first adumbrated by Jacques Herzog, a principal of the firm that became world famous for the "Bird's Nest" stadium at the 2008 Beijing Summer Olympics. Herzog supposedly scribbled a wavy form on top of a picture of the old, 1960s-era Kaispeicher A warehouse, and the idea quickly became embedded in Hamburg's civic consciousness.

The project is part of a major multibillion-dollar redevelopment of Hamburg's harbor, converting 19th-century brick buildings and empty lots into residential, office and commercial space. But a concert hall atop an old factory was counter intuitive. The constrained and irregularly shaped floor plate of the warehouse meant that the auditorium, above, would be abnormally vertical in its layout. And placing it so high above the ground meant that street life, so important to most urban developments, would need to be sucked up into the sky and redistributed on the terrace some eight floors above.

Entry to the concert spaces - which include the 2,100-seat main hall and a 572-seat recital hall - is accessed up a curving flight of wooden steps. When the building is open for performances, the visitor encounters no doors; the path up the steps leads directly into the lobby areas, which flow uninterrupted into the auditorium. The seating is in the round, or "vineyard" style, with the audience arrayed close to the stage in a set of shallow, interconnecting balconies.
