Andre Balazs’ plans to develop a hotel at JFK airport’s old TWA terminal are continuing, but differing opinions over the design have become a sticking point in the negotiations, sources tell us. Balazs is in late-stage talks with the Port Authority to build a 150-room hotel at the storied terminal, which also serves as a hub for Jet Blue. But a source tells us Balazs and the agency have butted heads with JFK executives over keeping the terminal’s historic Eero Saarinen architecture as opposed to creating a more modern design like those of Balazs’ Standard Hotels in the Meatpacking District, Miami and Los Angeles. “JFK [officials] said he wasn’t the right aesthetic fit,” our source snipped. But the Port Authority says otherwise: “After a lengthy and highly competitive request for proposals process, the Port Authority is engaged in negotiation with a high-quality hotelier for the adaptive reuse of the TWA Flight Center at JFK Airport. The Port Authority and the hotelier are committed to preserving the essence of Eero Saarinen’s iconic design in the final agreement.”
