The Los Angeles County Museum of Art (LACMA) has asked Renzo Piano to rework part of its expansion plans: gone is a glass-enclosed entry pavilion whose design was inspired by an Eames Case Study House; in is a corporate-sponsored entryway. The BP Grand Entrance, so named when the company made a $25-million gift to the museum, is an open-air gazebo supported by bright orange steel beams with a solar paneled roof and the British oil giant’s name emblazoned out front.
