Atsushi Kitagawara builds Learning Center in tokyo
On a triangular plot surrounded by roads, Atsushi Kitagawara has completed a Learning Center as a dynamic addition to a campus in Tokyo. Placed strategically at the heart of the campus’ master plan, the structure functions as a central hub for cultural activities and communication, accessible to the three adjacent high schools. The Center features a 500-seat lecture hall, a library, a railway simulator room, and a storage area dedicated to housing retired Marunouchi Line train cars used as teaching materials. Due to road setback regulations, the building’s above-ground volume is limited, leading to the use of a vast triangular mansard roof with reinforced concrete walls and steel frames.
a Distinctive Parabolic design
The exterior of the building by Atsushi Kitagawara (see more here) is characterized by its parabolic openings, which provides a visual connection between the library and the street. Custom-crafted aluminum extrusion profiles featuring curved cross-sections envelop the exterior walls, resulting in a façade marked by horizontal interplays of light and shadow that pay homage to the school’s history. Despite its compact layout, the upper-floor hall offers an excellent field of view and a strong presence, making it a versatile space for a wide range of school events. Its design incorporates specialized FRP acoustic panels on the walls, ensuring excellent sound clarity for lectures, musical performances, and theatrical productions.
