A CLT structural system is one of several sustainability considerations integral to RIOS’ newly completed 42XX mixed-used project that landed on the Westside of Los Angeles earlier this summer.

Located in Marina del Rey, the new 151,000-square-foot development includes three buildings and an offsetting landscape program that can sequester roughly a third of the total embodied emissions of the structure. 

The architects say the redevelopment of the 3-acre formerly industrial site into a new campus replete with EV-charging stations, bike parking spaces, a retail component, and a cris-crossing series of catwalks joins a conversation with other mass timber projects around L.A. County such as 843 N Spring Street in Chinatown and the Billie Jean King Main Library in Long Beach.

The linear park it created includes 12,000 square feet of landscaping and 33 mature trees meandered around the office blocks in a series of paseos and courtyards in such a way that leaves 45% of the design open to the sky without obstruction. The structure itself accounts for 70 tons of embodied CO₂.

RIOS says their use of a blended palette of concrete, timber, and glass for the hybrid structure equates to the removal of 262 cars from the road per year versus a typical all-concrete solution. 

The completion follows the groundbreaking for their multibillion-dollar One Beverly Hills project with Foster + Partners in February. The firm is currently hiring for a Marketing Pursuit Coordinator in Los Angeles via Archinect Jobs.
