Hitachi City Hidaka Elementary School is located in Hitachi City, where Hitachi, one of the world’s top 500 companies, was founded. The City of Hitachi has long been committed to improving and enhancing school facilities. In order to maintain the high quality of school buildings in the city, the city government consider that a new design firm for school should be built through a completely open bidding process.
Our design concept for the school is “a school that nurtures children’s dreams for the future”. It will serve as a symbol of Hitachi City, evoking the children’s vision of the future and their desire to learn. The outward expression of the school building gives a sense of movement and creates a variety of expressions depending on the perspective.

The existing school building is located on the south side of the site and the playground is on its north side. The fundamental issue was to construct a new school building while maintaining the existing school operations. In addition, the existing gymnasium and swimming pool had to be preserved and the impact on the neighboring residents to the north had to be fully considered.
In order to meet these requirements, the new building was designed as a rectangular shape on a north-south axis, adjacent to the existing gymnasium, without interfering with the existing classrooms and playground. A parking lot and a plaza for the future gymnasium were installed next to the building to act as a buffer zone to reduce noise and other impacts on the surrounding residential areas.

Japanese school buildings have a habit of being light-focused, so they are usually long and slender buildings located in an east-west direction. In contrast, our rectangular school buildings have the advantage of a smaller footprint, shorter interior movement distances, and smaller exterior walls. On the other hand, such a setup will inevitably result in some classrooms that do not face south, so it is necessary to ensure sufficient natural light and ventilation in the building. In order to solve this problem, we designed two open-air atriums in the school building, thus realizing the construction of this bright and open compact school building.

In the center of the building, there is a “Hidaka Children’s Hall and Multimedia Center” for children to interact with each other, and there are various teaching facilities around it.

The “Hidaka Children’s Hall” consists of a multifunctional hall and a lunch space, while the “Multimedia Center” consists of a library and a computer room. Surrounding the “Hidaka Children’s Hall and Multimedia Center” are the general classroom area, the functional classroom area, the administration office area, and the after-school childcare class.

The new academic building is a reinforced concrete with partial steel frame structure, consisting of walls and floor slabs. The walls are seismic walls with flat columns and the floor slab is a hollow slab with flat beams. The seismic walls as seismic elements will not only keep the building from deformation in case of an earthquake, thus ensuring the safe evacuation of people inside, but also maintain the safety of the building after the earthquake and realize the possibility of continuous use. The hollow slab not only has a higher degree of freedom when installing electrical equipment inside, but also can save the floor spacing to increase the clear height of the floor to create a wider space.

The walls that are perpendicular to the outer perimeter walls are formed by glass walls that gives an unobstructed line of sight to the atrium. Our expression of our intention stays minimal, allowing the structure itself to construct the bones of the building.
