The scraped lot at 8730 W. Alden Drive on the western edge of the Cedars-Sinai campus is not staying quiet for long. The former Thalians building is gone, cleared to make way for roughly 10 stories of laboratories, offices, and support space that would put a serious research high-rise on a relatively low-key Beverly Grove block.
The Alden Drive address is already familiar territory for the health system. It hosts research and outpatient operations, including specialized labs and clinics run by Cedars, according to Cedars-Sinai. That existing footprint means patients and investigators who already come here for care and clinical trials would see the site evolve rather than appear out of nowhere.
Permit filings reviewed by reporters describe the project as a 10-story, Type 1A high-rise of roughly 300,000 square feet, with the work permitted in January 2026, according to Urbanize LA. Reporting on a contractor outreach page from Rudolph & Sletten details the planned program: a lobby, vivarium, conference space, cafe, laboratories, and offices, plus a contemporary glass-clad tower in the rendering. City records cited in that coverage identify the project architect as a principal with CO Architects.
How this fits into Cedars' campus expansion
The Alden research tower slots into a larger building wave at Cedars, which already includes plans for a patient tower at San Vicente and Beverly boulevards. The main campus has been the subject of extensive environmental review and approvals in recent years, as outlined in planning documents from the City of Los Angeles. Separately, a replacement hospital at Marina del Rey is rising, a project covered by regional construction outlets that points to Cedars’ broader building push across the city, per Construction Review Online.
Who is building and what to expect
Industry project trackers list Rudolph & Sletten on the Alden Drive job, suggesting Cedars has turned to a contractor already seasoned in large hospital work, according to Levelset. Outreach materials referenced in prior reporting indicate the build will need highly specialized trades for laboratory and vivarium interiors, which can stretch out preconstruction and permitting. Neighbors can expect staged demolition, utility relocations and occasional lane or curb disruptions once the structure starts to rise.
Cedars-Sinai and its partners have not yet released a public construction schedule or an opening date for the new tower. For now, the project stands as a multi-hundred-million-dollar bet on biomedical space in Beverly Grove and another sign that the Los Angeles hospital skyline is not done growing upward.
