American studios Gensler and HDR, with Spanish studio Luis Vidal + Architects, referenced the hills and foliage of Western Pennsylvania when creating a terminal building for Pittsburgh’s international airport.

…The new structure, which the studios collaborated on, is three storeys high and placed in one of the voids between the terminal’s arms. It is capped by a metal roof that is raised in parts, creating clerestory windows.

Luis Vidal + Architects studio founder Luis Vidal said that he moved to Pittsburgh for an extended stay during the project and was taken with the rolling hills of the Allegheny Mountains and the region’s foliage.

The hills found their way into design in those rolling rooftop forms, while the foliage was expressed in the heterogeneous structural steel columns that support the massive overhang of the roof as it cantilevers over the entry programme.

The terminal opened last November, and locals love it.
