With OMA's Ippolito Pestellini Laparelli, Ellen van Loon, and Laurence Bolhaar as the design leads, the new complex will feature a facade inspired by the “gentle and sophisticated geometries of the architecture of the Vienna Secession”, the firm says.

Their design splits the project into two volumes, with the store up front and the hotel in the rear, and a green passage in between that leads visitors to a series of public roof-gardens.
