YK-huset, Collective residential building in Östermalm, Stockholm, Sweden.

YK-huset is an eight-story residential building in Östermalm featuring seven apartments per floor with varied sizes from small to large units. A central kitchen and restaurant on the ground level prepares and delivers meals to residents through a dedicated service elevator.

Built in 1939, the structure was designed by architects Albin Stark and Hillevi Svedberg as part of Sweden's progressive housing movement. This era saw architects experimenting with new forms of residential life that challenged traditional family living arrangements.

The house took its name from the Yrkeskvinnors Klubb (YK), the professional women's club that commissioned it, and its chair Célie Brunius wrote that a hostess there need not worry about setting the table, serving or cooking. A restaurant still operates on the ground floor, now Chinese, and residents can order meals sent up to their floor by the food lift.

The building is situated in an established Stockholm neighborhood with good access to transport and nearby shops and dining options. Visitors can explore the exterior and surrounding area, though it remains a private residential building not open for interior tours.

The ground-floor restaurant still operates, now as a Chinese restaurant, and residents can still order meals sent up to their floor by the food lift. The building also housed journalist Barbro Alving, architect Léonie Geisendorf and food writer Pernilla Tunberger.
