On Madison Avenue, a brutalist giant is about to acquire a new identity. Sotheby’s has purchased the Breuer Building—Marcel Breuer’s 1966 masterpiece once home to the Whitney Museum—for roughly $100 million. Renovations by Herzog & de Meuron, laureates of the Pritzker Prize, are already underway. By 2025, the auction house will relocate its headquarters there, transforming the granite landmark into a hub of free public galleries and high-profile sales.
But the building alone is only half the story. This autumn, Sotheby’s will stage two marquee auctions: the Pritzker Collection, valued at $120 million, and the Leonard Lauder Collection, estimated at $400 million. With Van Gogh’s Romans Parisiens (Les Livres jaunes) poised at $40 million and Gustav Klimt’s Portrait of Elisabeth Lederer expected above $150 million, the stakes are as architectural as they are financial.
