TAMA PUBLIC LIBRARY
Tama Public Library, designed by the Japanese architect Toyo Ito, is a cultural and community space located in the suburbs of Tokyo, Japan. It is a unique example of contemporary library architecture that represents the integration of form and function, as well as the combination of traditional and modern design elements. The building is characterized by its fluid, organic form, inspired by the natural landscape, and its use of natural light and air to create a welcoming and vibrant atmosphere. The library’s open plan, flexible spaces, and technology-rich environment reflect a changing approach to the role of libraries, making them more than just repositories of books, but also centers of community and cultural exchange. In terms of architecture, the Tama Public Library represents a departure from the traditional and static library spaces, towards a dynamic, flexible, and interactive model that supports lifelong learning and community engagement.
The building's main structural system uses steel arches and reinforced concrete. The arches are 12mm steel plates covered in concrete and form a cross shape at intersections for seismic stability. Lateral loads are transferred through the arches and vertical components are canceled out at the arch columns, while horizontal components increase the shear force down the arch column. The building also features an "emergent grid" floor plan made of curved lines, over 160 arches and 56 intersecting points.
The architectural program of Tama Public Library refers to the functional requirements and design specifications that guide the planning and design of the library building. It outlines the various spaces and functions that need to be accommodated within the library, such as reading rooms, reference areas, circulation desk, stacks, computer labs, and staff areas.
The design of the building takes inspiration from a geological cave and the Mosque of Cordoba, incorporating elements such as large glass windows and "random" arches with different heights and spans derived from a Bezier curve. The arches represent the stalactites of caves, appearing chaotic, and the design reflects various visual perspectives to reflect the surrounding nature.
