The firm of Rem Koolhaas, Office for Metropolitan Architecture, will be building a Kaufhaus des Westens (KaDeWe) department store, cum hotel, in Vienna’s historic center, right in the Museumsquartier. The project – OMA’s first in the Austrian capital – takes inspiration from and reinterprets the neighboring 19th-century Secession facades, and crowns the building with a roof garden that will treat shoppers to wonderful views of the city.
