SANAA is an architectural partnership based in Tokyo, led by Kazuyo Sejima and Ryue Nishizawa. Formed in the mid-1990s from a close collaboration between two architects who also maintained independent practices, the firm is widely known for a restrained, minimalist approach that emphasizes natural light, transparency and subtle spatial sequences. The name SANAA is sometimes confused with the Yemeni capital; see Sana'a and Yemen or the related Sana'a article for that subject.

Design approach and themes

SANAA's work often explores thin planes, simple geometries and the careful use of glass, metal and concrete to produce luminous interiors and porous boundaries between inside and outside. Projects favor open plans, gentle topographies and sequences of spaces that encourage movement and social interaction. Their practice demonstrates how economy of means and refined detailing can shape humane public buildings rather than relying on monumental gestures. The firm operates as a collaborative partnership within the broader field of architecture.

Notable projects

  • 21st Century Museum of Contemporary Art, Kanazawa — known for a circular plan and accessible galleries that encourage informal circulation.
  • Rolex Learning Center, École Polytechnique Fédérale de Lausanne — an undulating, open floor plate that serves as a campus hub and social space.
  • New Museum of Contemporary Art, New York — a compact, stacked-volume museum that rethought urban museum form.
  • Glass Pavilion, Toledo Museum of Art — an exploration of translucency and daylight in exhibition space design.

Recognition and influence

SANAA's international reputation was consolidated through competitions, built work and exhibitions. In 2010 the partnership received the Pritzker Prize, recognition that highlighted their influence on contemporary architectural thinking and teaching. Their projects are frequently studied in architectural education for lessons in proportion, material restraint and the creation of inclusive public space.

Practice and legacy

Beyond individual buildings, SANAA is credited with showing how subtle interventions and careful attention to light and plan can produce buildings that feel both modern and approachable. The firm continues to work internationally from its Tokyo studio, and its approach remains influential among designers interested in minimalism, spatial continuity and civic architecture.
