The Elbphilharmonie concert hall in Hamburg, Germany, by Herzog & de Meuron, which was inaugurated in January 2017, is the tallest inhabited building in the city, with a height of 110 meters (360 ft). The glass concert hall, which has 2100 seats in Vineyard style, is perched atop a former warehouse. One side of the concert hall building contains a hotel, while the structure on the other side above the concert hall contains forty five apartments. The concert hall in the middle is isolated from the sound of the other parts of the building by an "eggshell" of plaster and paper panels and insulation resembling feather pillows.
