SANAA (Sejima and Nishizawa and Associates) is a multiple award-winning architectural firm based in Tokyo, Japan. It was founded in 1995 by architects Kazuyo Sejima (1956) and Ryue Nishizawa (1966). For more than 20 years, the architects have worked together in their collaborative partnership, where it is virtually impossible to untangle which individual is responsible for what aspect of a particular project. Each building is ultimately a work that comes from the union of their two minds. Together they have produced major commissions, such as the 21st Century Museum of Contemporary Art in Kanazawa (both in Japan), the Glass Pavilion at the Toledo Museum (Ohio), De Kunstline Theater and Cultural Center (Almere, the Netherlands), the New Museum of Contemporary Art (New York, NY), Rolex Learning Center (Lausanne, Switzerland), and the recent Tsuruoka Cultural Hall (Tsuruoka, Japan).
The buildings by Sejima and Nishizawa seem deceptively simple. The architects hold a vision of a building as a seamless whole, where the physical presence retreats and forms a sensuous background for people, objects, activities, and landscapes. They explore like few others the phenomenal properties of continuous space, lightness, transparency, and materiality to create a subtle synthesis. Sejima and Nishizawa’s architecture stands in direct contrast with the bombastic and rhetorical. Instead, they seek the essential qualities of architecture that result in a much-appreciated straightforwardness, economy of means, and restraint in their work.
It may be tempting to view Sejima and Nishizawa’s refined compositions of lightness and transparency as elitist or rarefied. Their aesthetic, however, is one of inclusion. Their approach is fresh, always offering new possibilities within the normal constraints of an architectural project as it systematically takes the next step. They use common, everyday materials while remaining attuned to the possibilities of contemporary technology; their understanding of space does not reproduce conventional models.
They often opt for non-hierarchical spaces, or in their own words, the “equivalence of spaces,” creating unpretentious, democratic buildings according to the task and budget at hand. One example is the Almere project in the Netherlands, with its many simple classrooms and workshops, all presenting privileged views of the sea.
Another example is the Rolex Learning Centre in Lausanne, a space to be used by students day and night. Sejima and Nishizawa originally conceived it as a multi-story building, but, in the course of their deliberation, it became a single yet vast, flowing space. The building’s many spaces (library, restaurant, exhibition areas, offices, etc.) are differentiated not by walls but by undulations of a continuous floor, which rises and falls to accommodate the different uses, while allowing vistas across this internal “landscape for people.”
The relation of the building to its context is of utmost importance to Sejima and Nishizawa. They have called public buildings “mountains in the landscape,” believing that they should never lose the natural and meaningful connection with their surroundings. The New Museum in New York feels at home in the rough Bowery area of the city.
Their glass-enclosed museums, such as the Glass Pavilion at the Toledo Museum of Art in Ohio, blur the borders between inside and out, providing direct and changing views to the surroundings.
For architecture that is simultaneously delicate and powerful, precise and fluid, ingenious but not overly or overtly clever; for the creation of buildings that successfully interact with their contexts and the activities they contain, creating a sense of fullness and experiential richness; for a singular architectural language that springs from a collaborative process that is both unique and inspirational; for their notable completed buildings and the promise of new projects together, Kazuyo Sejima and Ryue Nishizawa are the recipients of the 2010 Pritzker Architecture Prize.
