McCarthy Cook & Company (MCC), a real estate firm with operations in California and Arizona, has filed plans for the refurbishment and expansion of the Trident Center in West Los Angeles. According to a case filing from the Department of City Planning, MCC is planning to add 120,000 square feet of new office space to the mid-rise complex at 11355 W. Olympic Boulevard.  The exact location and form of the expansion is unclear, although it could come at the expense of a parking garage and amenity deck located on the north side of the 3.6-acre property. The proposed improvements also include a full interior and exterior modernization of the Trident Center’s existing towers, as well as a reorganization of their ground-floor to include a 5,000-square-foot restaurant.  The twin 10-story buildings, built in 1983, feature a combined 383,000 square feet of office space. Construction of the project would be contingent on a series of discretionary approvals, including a general plan amendment and a height district change.  A timeline has not been announced. The property is located along the Olympic Corridor, which currently boasts the lowest office vacancy rate on the Westside.  As of now, the proposed Trident Center expansion is one of two substantial developments planned for the neighborhood, following a roughly 200,000-square-foot building slated for the current home of Martin Cadillac.
