A 46 metre-long wall of uninterrupted concrete lines the north elevation. Narrow lengths of glazing run along its top and bottom, bringing light through to the floor and ceiling of the hall.
Larger windows span the southern elevation so that students elsewhere on the campus can catch a glimpse of activities taking place inside, while students inside can look out towards the surrounding woodland.
Structural timber columns are positioned along this facade to take some of the vertical load from the wooden roof, which protrudes over the edges of the walls.
Design Intent
The Kobe International Junior High School and Senior High School Harmonie Hall was based on an idea of a clear and open axial plan utilising concrete and wood to respond to the campus' history while creating a new relationship with the natural landscape. Harmonie Hall is an ancillary facility that includes a teacher's room, storage, toilets, and a gymnasium that can be used as both a basketball court and an auditorium.
The south side leads to an existing building and is comprised of a long 20m wood structural span for views of the woodlands supported by a 6m high and 46m long concrete wall. Opening the building to the lush ecosystem of the north campus was a natural configuration.
By supporting the horizontal force with concrete walls on three sides, with the north side being the exception, the structural roof frame was designed to transfer vertical load to the wooden poles on the north facade.
Furthermore, by providing a sufficient aperture to the wind and natural landscape, a space filled with light and consistent breezes from the north is realised.
Also, by using vegetation identified from research and field surveys, trees are transplanted from the construction staging areas while simultaneously cultivating local seeds as a means to visually and biologically produce a landscape of continuity with the local context.
Site and Context
The context for this project was a combined junior and high school located in the peaceful hills overlooking Suma with a view of the Akashi Straits and Awaji Island. This school was established in 1992 with aims to foster women with prolific knowledge and grace, and the campus has since been designed with the theme that the campus has made an impression on their memory. The exposed concrete of the design provides a sense of integration with the campus which includes many memorable places.
