Roughly half-a-year after breaking ground, a minor expansion project is wrapping up exterior work on the Sony Picture Studios lot (SPS).  The new Studio Support Building, located near the Sony complex’s Mentone Avenue gate, will contain approximately 23,000 square feet of production and office space within its four-story frame.  Exterior materials appears to consist primarily of earth tone stucco, broken up by misaligned windows. More grandiose expansion plans are also in the works for other parts of the SPS lot.  Over the summer, the studio filed plans with Culver City for a new eight-story, 218,000 square foot office building.  The mid-rise structure would replace a current parking lot adjacent to SPS’s main entrance on Overland Avenue. On the south side of campus, the studio proposes a new 52,000 square foot production facility.  The low-rise edifice would replace a series of nondescript structures adjacent to the aforementioned Studio Support Building. To accommodate the new office and production space, SPS also proposees a commensurate expansion of its Culver Boulevard parking garage.  Plans call for the six-story structure to be widened on its eastern and western sides, while its rooftop level would be extended to cover the full footprint of the garage.  Altogether, the proposal would yield a net increase of over 1,300 parking stalls.  Some preliminary work for this portion of the project appears to have already started, with heavy equipment and protective fencing now on-site at SPS’s Culver Boulevard gate.
