The Chiat/Day Building is a commercial office building located in the Venice neighborhood of Los Angeles, California. Built between 1985-1991 for advertising agency Chiat/Day (now TBWA\Chiat\Day) as its West Coast Corporate Headquarters, it was designed by architect Frank Gehry. The building is notable for the three different styles used in the main facade on Main Street, particularly the massive sculpture of binoculars that function as both a car and pedestrian entrance. The binoculars, which house two small conference rooms, were designed with help from Claes Oldenburg and Coosje van Bruggen. The "eyepieces" for the binoculars act as skylights. The 75,000 square-foot building was delayed for a few years after hazardous materials were found on the building site, requiring removal. TBWA/Chiat/Day is no longer a tenant in the building, having moved to another area of Los Angeles known as Westchester.
