Earlier this month, developer Hudson Pacific Properties commenced excavation for Icon, a 14-story office tower on the Sunset Bronson Studios campus (SBS). The 200-foot tall edifice, designed by architecture firm Gensler, will rise from the corner of Sunset Boulevard and Van Ness Avenue, creating a total of 315,000 square feet of creative office space.  Artistic renderings portray a mid-rise structure, described by the Architect’s Newspaper as consisting of “five rectangular, stacked volumes, offset horizontally to create exterior terraces.” Icon is part of a $150 million expansion of Sunset Bronson Studios which will completely remodel the eastern half of the approximately 10-acre campus.  Plans call for the construction of a 90,000-square-foot production facility and a 1,600-car parking garage along Van Ness Avenue, both of which broke ground last September.  The project also includes the refurbishment of the SBS Executive Office Building, a 1920s structure which once housed the headquarters of Warner Brothers. The Los Angeles Times previously reported that completion of the SBS expansion is expected by late 2016.
