Apt. 1601
Tod Williams and Billie Tsien, architects.
Years in the Apartment: 34.
Architects Tod Williams and Billie Tsien have lived, worked, and raised a family in their sixteenth-floor aerie. Their studio will house an emergency generator if the proposed plans go through. Even if Williams and Tsien have to leave, they hope the space can be used by other artists. “It’s not about us,” says Tsien. “It’s about this place as a community for artists.”
