Avi Lerner, owner of the former home of health insurer Anthem Blue Cross, has proposed a plan to redevelop the building called Warner Landmark at 21555 Oxnard St. in Woodland Hills.While Lerner has yet to submit plans to the Los Angeles Planning Department, he has shared his vision with the Planning and Land Use Management Committee of the Woodland Hills Warner Center Neighborhood Council.The plan proposes an adaptive reuse of the officer tower with amenities such as restaurants and a 36-room hotel. Parking would remain in an existing subterranean garage.The transformation would entail two phases. Phase II would see the construction of a neighboring 300-key hotel tower perched atop 17,000 square feet of supermarket space.Lerner has enlisted CallisonRTKL and landscape architecture firm Relm to design the new Warner Landmark complex.Since Anthem Blue Cross vacated the 14-floor, 450,000-square-foot building in late 2018 and relocated to another Warner Center office park, brokers at CBRE Group have struggled to market the building to other tenants.If approved by the city of Los Angeles, Lerner’s new plan for Warner Landmark would be the latest to unfold at Warner Center. Nearby, Unibail-Rodamco-Westfield has plans for a $1.5 billion overhaul of its Promenade mall. There are also a hotel planned for the parcel that has long hosted Fry's Electronics store across the street from the Landmark on Canoga Avenue.
