  • • Demolition of existing structures, including a 30-story tower, is currently underway, positioning the project to move into active construction phase with secured financing.

Summary
Vornado Realty Trust and Citadel CEO Ken Griffin have closed financing for one of Manhattan's most significant commercial real estate development projects in recent years. The $3.3 billion construction loan for 350 Park Avenue marks a historic milestone as the largest construction loan ever issued in New York City, according to reporting on the transaction.

The 350 Park Avenue development is a planned supertall office tower totaling approximately 2 million square feet. Demolition of the current site, which includes a 30-story existing structure, is underway. The equity ownership structure reflects Griffin's lead role as primary investor: Citadel holds approximately 60% ownership, Vornado—one of the nation's largest real estate investment trusts—maintains 36%, and the Rudin family, a prominent Manhattan real estate operator, holds 4%.

Citadel's operational commitment to the property underscores the project's anchor tenant dynamics. The hedge fund has committed to occupying approximately 1 million square feet of the completed tower, establishing itself as the anchor tenant. This significant occupancy pledge from a major institutional tenant likely strengthened financing underwriting and provided lenders with high-quality lease revenue certainty, a critical factor in construction lending decisions.

The financing closes a major capital chapter for the development, enabling the project to transition from demolition into full construction. The $3.3 billion facility represents substantial institutional confidence in Park Avenue's premium office market positioning and the feasibility of leasing Class A space to institutional-grade tenants at Manhattan's highest rental rates.
