“We are thrilled to relocate Flatiron's headquarters to One SoHo Square in the spring of 2018,” says Nat Turner, co-founder and CEO of Flatiron Health. “New York has been our home since launching in 2012 with just a handful of employees in a shared workspace. The move to the new office—almost double our current size—gives us the much needed flexibility to grow our team, working to accelerate cancer research in the months and years to come.”

Designed by Gensler, One SoHo Square has some of the largest floor plans available in Midtown South, ranging from 12,000 square-foot pre-built suites to a 90,000 square-foot contiguous block, newly redesigned penthouses and private outdoor space. The structure has a 15-story east tower, in which Flatiron Health will be located, and a 13-story west tower. They are connected by a glass cube lobby and central core that overlooks SoHo Square Park.

Other tenants in the building include Glossier, MAC Cosmetics, Trader Joe's, Managed by Q, DoubleVerify and Warby Parker.

Originally built in 1904, and renovated in 2015, One SoHo Square also has the address 161 Sixth Ave. In March 2016, Stellar Management in a joint venture with Imperium Capital, purchased both towers, totaling 766,000 square feet from Rockpoint Group for $630 million. Flatiron Health is moving from its current offices at 500 Fifth Ave., a structure located between W. 42 and W. 43 streets, built in 1931 and renovated in 2012. The building information was obtained from Real Capital Analytics.
