Generative artificial intelligence firm Harvey secured a full-floor lease expansion at 315 Park Avenue South, Columbia Property Trust’s boutique, 20-story office building.
Harvey is doubling its space in the building to 34,100 square feet. The San Francisco-based firm, which initially leased the 17,050-square-foot fifth floor earlier this summer, has added the entire 17,050-square-foot seventh floor. Harvey, which is backed by OpenAI, Sequoia Capital, Kleiner Perkins and Google Ventures, is dedicated to building the future of professional services.
“We’re thrilled to be able to accommodate Harvey’s expansion needs so soon after establishing their New York office at 315 Park Avenue South,” said Columbia Property Trust’s Head of Real Estate, Ted Koltis. “Harvey’s decision to quickly double its presence is a testament to their continued success as well as to 315 Park Avenue South’s ability to attract cutting-edge firms to a world-class working environment in one of New York City’s most vibrant neighborhoods.”
The 332,000-square-foot tower is currently home to various technology and finance firms, including PitchBook and Twitch. Its retail spaces are currently occupied by luxury fitness chain Equinox, the robot-run food purveyor Kernel and Just Salad.
The century-old building blends classic exterior architecture with modern building systems, earning the tower Energy Star, Fitwel, LEED Gold and WiredScore Platinum certifications.
