the ‘DH triangle school’ explores the possibilities of educational architecture through staging relationships between people, place, and learning. each face of the facility faces a distinct area: a playground to the north, a hill to the east, and an existing middle school building to the west. these three environments were used by nameless architecture to aid in design and organization of the plan. the north and east façades features a transparent skin with vertical louvers, which maintain an appropriate balance between illumination and privacy.

the existing building to the west, compared to the new structure, has a much different function. it was decided that the ‘triangle school’ needed to be visually and functionally distinct from the other. for this, the entire face is concrete with a single triangle-shaped entrance window to provide minimal connection.

unlike the complexity of the three sides, the interior is largely open and sits in the center of the building. on the second and third floors — class room levels — a courtyard opens up to the sky. the space helps create a welcoming learning environment by naturally bringing light inside, and also provides a small place for students to enjoy the sun and get a bit of fresh air. the ‘DH traingle school’ is located in namyangju, nearby seoul, south korea.
