Sotheby’s Unveils Plans for Breuer Building, Announces Opening Date
Sotheby's will open its new global headquarters in the Marcel Breuer–designed building at 945 Madison Avenue on November 8, 2025, after a renovation by Herzog & de Meuron with local partner PBDW Architects. The Brutalist landmark, originally completed in 1966 for the Whitney Museum of American Art, later housed the Met Breuer and the Frick Collection during its renovation. The project restores Breuer's original open gallery floors, adds state-of-the-art lighting and climate control, and preserves period details like the lobby's domed ceiling lights. The opening will feature a free public exhibition of Modern and Contemporary art ahead of marquee auctions starting November 17, with design sales and Luxury Week following on December 5, and a fine-dining restaurant by Roman and Williams opening later in the winter.
