High-tech, three-story house with a central courtyard

For this project, drafti was asked to emulate the design concept of Sir Norman Foster. This is a three-story detached house that translates the high-tech architectural vocabulary associated with Norman Foster—such as orderly structural grids, exposed steel framing, expansive glass surfaces, lightweight metal finishes, and integrated cores with open floor plans—into a residential scale. Designed as a private residence for a family of four, the project has a total floor area of approximately 300 m² (roughly 100–120 m² per floor). The building mass is configured in a square (□-shaped) layout that encloses a central courtyard. The exterior facing the street and neighboring properties is enclosed with metal panels and minimal openings, while the side facing the inner courtyard features full-height glazing; this arrangement ensures both privacy and abundant natural light within a densely built-up residential area. The program is vertically zoned: the ground floor is kept open, accommodating only a pilotis parking area, the entrance, and a multi-purpose room; the second floor serves as the main living area, containing the living room, kitchen, and dining room; and the third floor constitutes the private zone, featuring three bedrooms and an outdoor terrace. The site is assumed to be a regular-shaped plot bordering a 6-meter-wide road to the south, subject to "due-north" sunlight setback regulations.

Why these numbers
- 3개bedroom_count
The first floor is left open for pilotis parking, entrance, and multipurpose room, with main living spaces on the second floor and three bedrooms (master bedroom plus two children's bedrooms) arranged on the third floor.
- 6000mmstructural_grid
The structural grid is organized in 6m modules, and the grid must be legible in both plan and elevation.
- 4500mmcourtyard_width
The plan is composed of a U-shaped configuration surrounding a central courtyard, and the courtyard must remain visually continuous from the second and third floors.
- 4500mmcourtyard_depth
The plan is composed of a U-shaped configuration surrounding a central courtyard, and the courtyard must remain visually continuous from the second and third floors.
- 250m2assumed_site_area
Site area (m²) and boundary measurement dimensions: undetermined — cadastral map and existing site survey required. Assumed value of 250m² (approximately 76 pyeong) used for review.
- 6000mmfront_road_width
Road frontage condition: assumed as regularly-shaped site with one-side frontage on a 6m road to the south (based on design response criteria). Actual road frontage direction and width require verification through site survey and road register confirmation.
