Olmsted, Vertex Ink 67K SF in Deals at Newly Acquired Park Ave. South Offices

Olmstead Properties and the investment platform Vertex have signed more than 67,000 square feet of leases at 373 and 381 Park Avenue South, including new deals with real estate brokerage firm The Corcoran Group and AI company Stuut Inc., as the new owners kick off an extensive repositioning of the Flatiron District office buildings.

Ownership said the leasing activity—representing roughly 20% of the two buildings’ available space within four months of the acquisition—underscores early tenant demand for the properties as the new ownership launches upgrades and newly built prebuilt office suites.

The Corcoran Group has signed a 14,710-square-foot lease at 381 Park Ave. South, where the brokerage will relocate from the nearby 387 Park Ave. South under an 11-year lease, with occupancy expected in summer 2026.  Corcoran was represented in-house by Paul Wexler.

Stuut Inc signed a 9,043-square-foot lease at 373 Park Ave. South in a short-term agreement. The tenant was represented by Brandon Cooperstock and Sean Hoffman of Cushman & Wakefield.
