How does the new Lynda and Stewart Resnick Pavilion fit into the LACMA family? Surely you must remember the Arnold Schwarzenegger/Danny DeVito movie “Twins.” I will not go so far as to suggest that this is what the worldly architect Renzo Piano had in mind when he designed the Resnick Pavilion at LACMA and placed it right next to his other contribution to “the campus:” the Broad Contemporary Art Museum. The resulting effect, however, is not far off. As viewed from the Entrance Pavilion, the Resnik Pavilion looks like the less-developed sibling of the taller, more imposing BCAM. It’s, well, the grand Piáno and the baby Piáno (insert restrained, WASPY laugh here). Both buildings are topped by a saw-tooth roof, are constructed from the same pale travertene marble, and are embellished with this or that functional accent in fire engine-… sorry, “Renzo-Red:” a staircase (BCAM) or an air-duct (the Resnik).But these are just surface details. As LACMA CEO and director Micheal Govan assurs us, the Resnik Pavillion is nothing but grand when viewed from the inside.
