Chofu campus of Toho Gakuen School of music by Team Yamanashi in NIKKEN SEKKEI
This is a plan of a college of music in a typical low-rise suburban city.
Up until that point, volume arrangements of large-scale buildings had been often discussed from limited methodologies such as creating a “city in a park” by surrounding them with a buffer zone, “formation of a group” by considering the buildings as a colony, or “The Nolli map” method by inverting negative voids and positive volumes.
Here, a “porous” arrangement was pursued as a system, which creates a sense of continuation from inside to outside, and delicately picks up contexts, while not spoiling the sense of unity that can only be provided by large-scale plans.
Due to the superfluous consciousness of ambient noise and sound insulation, many music college facilities employ a style in which the exterior appears as a closed box and the lesson rooms are lined up along central corridors in a jail-cell-like manner in the interior. It is ironic that the learning places of creative activity resembles what we can see in solitary confinements. It was required for us to overcome this style, as well as to establish the presence as a music college while flexibly arranging the lesson rooms.
The building was planned to have three levels: two levels aboveground, and one underground. On the second floor, the main function, lesson rooms, were freely placed according to the program without any restrictions such as standardized span dimensions and grid lines. By exposing the volume of the lesson rooms to the exterior, the uneven, small courtyard-like spaces in between neighbors were created, and the volume of the building was broken down.
Corridors are placed between the lesson rooms for better sound insulation. This resulted in inserting the exterior into the interior which lure wind and natural light. The louder ensemble room is placed on the underground floor, whose sound insulation is better. Corridors and a sunken garden are created, with the same state of the second floor. The characteristic “porous” volume arrangement, that is large-scaled but possesses a sense of unity while maintaining continuity of the interior and exterior spaces, was born.
As a result, a group of porous walls on uneven grids both exists on the underground floor and the second floor. The in-between first floor, the “campus” is a completely different space, by pillars placed at the intersections of the above and below floors. The campus unfolds under the porous second floor. It makes the college not a closed space detached from its surroundings, and provides a sense of continuity with the neighborhoods.
The porous volume arrangement, which is created by the triple-layered uneven grids, in fact works as a system that flexibly adjusts various issues that are inevitable in a large-scale project and resolves into the diversity of the spaces.
For such adjustments, it is more adequate to use a new method with computers that incorporates three-dimensional feedback loops, rather than using a predetermined harmonic additional line, such as the conventional “grid line”. The subtle “changes” and “misalignments” are created by persistent adjustments using computer. In the porous figure that is designed for positively placing the large-scale building in the random context, these embed a sense of continuity and surprises as if wandering around a village. This resulted in creating rich spaces and the presence as a whole.
