3D Building

English description provided by the architects.

A music preparatory academy operates under a specific spatial logic: densely packed soundproof practice rooms, their number directly tied to tuition costs.

The spatial principle stems from the displacement of corridors. In a conventional music academy, practice rooms line a single central corridor. By shifting the corridors vertically against each other, a residual space emerges between them — a hall.

Rather than reducing the number of practice rooms, small portions of each room's rear area — the space behind a seated or standing musician — were redistributed to form this shared volume. Within the constraints of cost and efficiency, a common breathing space is created.

The organizational principle of the floor plan is carried through to the exterior surface, splitting the skin along the same lines, so that structure and cladding are legible through the same logic.

The interior flooring, developed in collaboration with graphic designer Oh Hyejin, rearranges standard vinyl tiles in new configurations — making the familiar strange.

The conditions of a music academy govern every decision. Individual windows for each practice room would compromise acoustic isolation.

Soundproofing — through stud separation, double-layered walls, and acoustic infill — was resolved collaboratively with the contractor on site.

In the basement, a compact performance hall offers a spatial counterpoint to the density of individual practice above: a collective, open room against a field of private, enclosed ones.

All buildings are, of course, three-dimensional. But like the word 3D itself — once used to describe new technology with a sense of wonder — this building finds something unfamiliar within the ordinary.
