LEVER Architecture, a Portland, Oregon­–founded architectural practice that’s garnered national praise for its pioneering embrace of mass-timber construction, is heading to the other Portland—the similarly forest-flanked one in Maine—for a $100 million revamp of that city’s most venerable public art institution.

The firm, a 2017 Design Vanguard, has been announced as winner of an international competition seeking design architects for a campus-unifying expansion of the Portland Museum of Art (PMA). Dubbed The PMA Blueprint, the first-in-four-decades expansion project will more than double the existing footprint of the museum by yielding a new 60,000-square foot wing at 142 Front Street that knits together a quartet of disparate but architecturally significant buildings centered around downtown Portland’s Congress Square, including the historic McLellan-Sweat Mansion and Henry N. Cobb’s emblematic red-brick Payson Building opened in 1983.
