"Pegged to the centenary of the Bauhaus founding, the $31.5-million-dollar Bauhaus Museum Dessau will showcase 49,000 artifacts from the Bauhaus Dessau Foundation—the second largest Bauhaus collection on earth. Addenda Architects, an upstart collective from Barcelona, is heading up the innovative building-within-a-building design. To the untrained eye, the museum looks like an enormous black box floating inside a transparent enclosure. The box in question gives curators nearly 23,000 square feet of exhibition space. The glassed-in ground floor, meanwhile, will be home to an “open stage” for interactive art installations, film screenings, dance and theater performances, and artist talks. The museum opens September 8."
