The Albright-Knox Art Gallery in Buffalo, New York has just revealed the design of its new $155 million expansion by OMA New York. The project, which OMA won in competition in June 2016, will sit opposite the museum’s original 1905 Beaux-Arts building, in what is currently a parking lot.

The signature feature of the new building is a translucent cascading facade-cum-roof, which acts as a wraparound promenade that encloses a flexible space for both art and events. “More and more, a museum needs to act as a civic center,” says OMA New York director Shohei Shigematsu. “Before, the gallery box defined the facade, but here, it is shaped by this space for more diversified activities.”
