Onni Group's updated plan for the redevelopment of the Times Mirror Square complex has been unveiled through an initial study published by the Los Angeles Department of City Planning.

The project, which first emerged in late 2016, calls for demolishing a 1970s expansion of the historic Los Angeles Times headquarters and the construction of modern high-rise towers in its place. Onni would also retain and rehabilitated the original 1930s and 1940s buildings as creative office space.

Architecture firm A.C. Martin is designing the project, which calls for towers of 37 and 53 stories along Broadway between 1st and 2nd Streets. The new construction would create 1,127 residential units, seated atop approximately 34,000 square feet of street-fronting commercial space and a parking podium.

With peak heights of 665 feet and 488 feet above street level, the towers are similar in scale to similar high-rise developments planned nearby, including those at 232 W. 2nd Street and within the Grand Avenue Project.

The new buildings would be separated from the historic components of Times Mirror Square through a wide pedestrian paseo, cutting the full length of the block between 1st and 2nd Streets. Renderings portray a landscaped, open-air environment lined with restaurants and outdoor seating.

The upper floors of the historic Times and Mirror buildings will offer approximately 285,000 square feet of office space at the time of the project's completion, while their ground floors would be activated with retail space and a grocery store. The roof level of the central plant building is slated to be repurposed as an outdoor deck.

Onni's proposal would restore the original appearances of both the Time and the Mirror Building, which were designed by Gordon B. Kaufmann and Rowland H. Crawford respectively.

Construction of the project would occur over a single phase, with a potential four-year build out between 2019 and 2023.

The Times Mirror Square redevelopment dovetails with a recently approved master plan for the Civic Center, which looks to reinvigorate the sleepy district of government offices with apartments, shops and restaurants.
