This is an extension project of an existing nursing school building, which was partially demolished. The plan of the existing building was that an outside corridor enclosed a courtyard. I placed a new outside corridor as it was. At the same time, I tried to create the structure to be more open to connect outside and inside, as well as being warm and protective for children.
Small boxes, 6 feet on each side, are placed in order, and gaps in between them are large rooms so that the plan arranges alternative rooms of small and large dimensions. The small boxes support a roof instead of columns. To enable a large space, beams extend in an oblique direction from each box and are connected above. The interior walls and ceilings consist of pentagonal and square surfaces. These generate unique polyhedron spaces like a honeycomb.
The small boxes not only support as a structure, but also contain necessary functions such as a storage space for chairs and tables, restrooms, shoe cupboards, and so on. They also contain playrooms with books and toys, and children love such small spaces.
The large rooms are bright open spaces with top lights, and allow dancing in a circle and drawing pictures. These rooms are connected to each other, and only separated with sliding doors. By keeping sliding doors open, children can run around within the connected rooms.
Under the top light, there are aluminum louvers to make the face of a polyhedron. In summer, the warm air is discharged through the top lights, and fresh and cool air is provided from windows below. In between top lights and louvers, LED lights are installed.
The repeatedly placed small boxes and large polyhedron rooms can be extended anywhere.
