Eishin Campus – High School: Central Hall

1982 to 1985

Nihongi 112-1, Iruma-shi, Saitama Prefecture, Japan

Educational, Realized , Construction completed in 1985

The Central Hall is located at the end of the homebase street. Α student gathering area with four-foot-thick concrete base walls and arched openings, with built-in benches, which double as entrances to the building. Arches and seats form alcoves, and the piers support the timber frame and roof truss of the upper structure. The roof truss is made of Douglas fir curved members and contributes to the good shape and positive space of the interior.

Design and construction process:

The work on the design and construction of the project performed by C.E.S. was divided in five phases. 1) Creation of a pattern language; 2) Layout on the site; 3) Design of the individual buildings; 4) Working drawings; 5) Construction 1) The first step in the project was to create a pattern language for the school. This was achieved by spending a total of 1200 man-hours discussing the many requirements with the various teachers, professors and staff of the Eishin School. The results of these interviews and discussions were condensed into a coherent vision, which was written up in the form of patterns (a written documentation that describes a physical reality). A copy of the pattern language that was created had been included as part of the submission to the client. 2) The next step in the process was to lay out the various buildings and outdoor spaces on the site. The main goal in this step was to position the buildings so that they form positive outdoor spaces, and to use stakes to mark the corners so that all of the concerned parties can get an actual physical sense of how the site will feel when the buildings were built. When the site felt as though it was laid out just right, the position of each building was recorded. From this record an overall site plan was drawn. At the same time that this process was going on, a large-scale site model was under continuous development in the C.E.S. office in Japan, where the users could see it and discuss it, day by day, as the work proceeded. This played an important role in helping to establish a direct connection between the users, and the site plan of the finished campus. 3) The third step in the process was the design of the individual buildings. In the Eishin School project, 35 buildings in all were designed. During this phase, various types of construction were considered which could capture the vision of the project. Some of the buildings were designed as concrete block, some were plastered concrete, and others were constructed out of heavy timber. 4) In the fourth stage, preparation of working drawings and permission, C.E.S. did its own engineering and construction estimation. Many of the buildings have unique engineering behavior, which was developed on the C.E.S. computer programs by the C.E.S. engineering staff. C.E.S. also did extensive full-scale mock-ups of crucial materials and construction details during this stage, to guarantee that the final buildings would have the emotional reality with project staff was seeking. 5) In the construction phase of the project C.E.S. worked with Fujita Construction Company, the sixth largest construction company in Japan. During this phase, C.E.S. kept a full scale on-site office in place throughout the work, and had its own staff working closely with the details of the buildings, every single day. Many on-site changes, decisions and details of the buildings were made as the construction proceeded. Because of our method of cost accounting, these changes were made without increasing the cost of the finished project.
