A surgical robotics company is expanding its new Waltham space to double its capacity for testing and manufacturing.

Vicarious Surgical, a publicly traded company that develops a first-of-its-kind surgical robot, is moving into 30K SF at 62 Fourth Ave. in Waltham. The property sits near Vicarious’ 8-month-old headquarters lease for 42K SF at 78 Fourth Ave., a former headquarters for robotics-maker Boston Dynamics.

Both spaces are owned by Fourth Avenue LLC, a company owned by James Magliozzi, according to Securities and Exchange Commission filings published earlier this month. A representative for J.F. White Properties, a Magliozzi-owned company, confirmed it was the landlord of the Vicarious Surgical spaces.

“Increasing our physical footprint allows us to more than double our capacity for development, testing, and manufacturing; this expansion will ultimately enable Vicarious Surgical to welcome broader hospital and surgeon engagement,” Vicarious Surgical CEO Adam Sachs said in a release.

The former office and research and development spaces were good fits for Vicarious’ operations and growth, Lincoln Property Co. Senior Vice President Tim Latham, who represented Vicarious Surgical in lease negotiations, said in a statement Wednesday.

Vicarious, which relocated from Charlestown at the beginning of the year, will pay approximately $25 per SF at 62 Fourth St. and $30 per SF for its HQ beginning next April after a lease amendment period, according to an SEC filing. Its lease will run for 10 years and includes a five-year extension option, ensuring a long-term home in the bustling office and life sciences submarket approximately 14 miles west of Boston.

Vicarious Surgical was granted Breakthrough Device Designation by the U.S. Food and Drug Administration in 2019, the first designation for a surgical robot by the FDA, according to Vicarious. The firm’s backers include Bill Gates and the prolific venture capital firm Khosla Ventures.
