PORTLAND, Maine — LEVER Architecture has been named the winner in the much-heralded international competition to design an expansion of the Portland Museum of Art (PMA) in Maine’s largest city. The $100 million project will add approximately 60,000 square feet of space to the campus in the form of a new facility that “knits together” with the PMA’s four existing downtown buildings. ….LEVER, which has recently stood out for their application of mass timber constructions, will again incorporate the material heavily into the expansion’s design along with glass and terra cotta culminating with a curvilinear roofline meant to frame the movement of the sun in what the firm says is a reference to the local Wabanaki Indigenous community’s conception of place. …“This is one of the most significant moments in the PMA’s 140-year history,” museum director Mark Bessire said.
