The Seoul National University Museum is defined by its siting on the side of a small hill, close to the entrance of the university. The building?s form was conceived as a basic rectangular box, theoretically sliced diagonally by the incline of the hill. This form is then raised up on a small central core ? the only point of contact with the ground ? so the building is nearly all cantilever, extending up and down the hill, following the topography precisely and appearing to hover above it. The museum both defines and defeats the hill, and, by keeping the ground beneath it largely free, becomes an attractive conduit between the university campus and the outside community.Both outside and inside, free-flowing circulation was key to the thinking behind the building. The central core is an atrium with a square-spiral staircase connecting the various program areas: exhibition, education, library, and operations. The educational spaces ? the lecture hall and auditorium ? exploit the slope formed by the slice for their tiered seating. The library inhabits the structural core of the building. The exhibition space, being the primary function, inhabits the entire top floor. But it is also able to invade the educational spaces below by means of an angular ramped circulation path; the use of materials in these spaces also signals the potential continuity in the program. Elsewhere, materials vary, and include concrete flooring, plywood paneling, and translucent plastic paneling over fluorescent lighting. The museum?s fade is also translucent, revealing the structural steel truss work beneath.
