Construction is slated to begin in early 2020 for a project that will expand and modernize the Trident Center, a 1980s office complex in the West Los Angeles-Sawtelle neighborhood.

The project site, located at 11355-11377 W. Olympic Boulevard, currently consists of more than 300,000 square feet of office space in two 10-story buildings connected by a shared parking garage and amenity deck.  McCarthy Cook and Northwood Investors, the real estate investment firms which own the Trident Center, has obtained entitlements to add approximately 115,000 square feet of rentable space - including offices and retail.  The rebranded property will be known as Lumen West L.A., and offer approximately 555,000 square feet of enclosed and outdoor office space, as well at 15,000 square feet of street-fronting shops and restaurants.

Designed by Gensler, the project will create new room for offices by extending the footprint of the building's podium above what is currently a grass plaza fronting Olympic Boulevard.  Additionally, plans call for bridging between the two towers at several locations, creating opportunities for larger offices on a single level.

An existing rear-facing amenity deck - seated atop the building's parking garage - is to be converted into a one-acre amenity space for use by tenants and private events, featuring food-and-beverage venues and sports courts.  Additional open spaces are planned in the form of a grand central staircase, a fitness center, and several terrace decks.

The proejct will be capped by a penthouse suite, featuring 22-foot floor-to-ceiling glass and a mezzanine level.

Plans also call for an existing 1,924-car parking garage to remain in place, though the property will also offer a shuttle to the nearby Expo/Sepulveda Metro station.

Completion of themore than $300-million development is anticipated in early-to-mid 2022, according to Mike Coppin, a vice president of McCarthy Cook.

Lumen sits two blocks west of Sawtell Boulevard, and one block east of the corner of Olympic and Butler Avenue, where a five-story, 70-unit apartment complex is now taking shape.
