About 12 Degrees 住宅インテリアデザイン

「12 Degrees」は、中高層階に位置する3ベッドルームのマンションのための住宅インテリアデザインである。天井面は二方向へ立ち上がり交差することで、梁を隠しながら自然光を室内の奥へと導く。傾斜面は6度から12度の範囲で設定されている。テレビウォールもその角度に合わせて傾斜し、暖炉のモチーフを取り入れることでクールな色調に温かみを与えている。アイランド状のレイアウトがリビングとダイニングのゾーンを規定しつつ、動線の開放性を保っている。人造石と強化ガラスの家具が、重厚感と透明感を併せ持つ空間を生み出している。

Unique Properties: '12 Degrees' features dual-directional ascending ceiling planes that intersect, concealing beams while directing daylight deeper into the space. The TV wall tilts in alignment, integrating a fireplace motif that warms the cool palette. The social area uses a dual-division 'island' layout, defining living and dining zones while preserving negative space. Engineered stone and tempered glass furnishings combine solidity with transparency, enhancing visual flow and spatial flexibility.
Dimensions & Packaging: The residence retains its original three-bedroom layout, with adjustments refining the master bedroom and dressing room for improved flow. Boundaries between social and private areas remain clear, and two guest rooms accommodate visitors. Subtle elevation changes and ceiling integration expand the horizontal scale of the social area, enhancing visual depth and supporting larger gatherings without altering the overall room count.

Production Technology: The social area is composed of silver-gray and soft white tones. Imported special paints, Italian tiles, and metal panels layer subtle gradations. Large floor tiles reduce joint lines, reinforcing spatial purity. In private area, the color palette shifts to deep graphite black. Low- saturation coatings envelop the master bedroom and dressing room, forming strong contrast. Light acts as a colorist-cool by day, warm at night.
Design Challenge: The challenge lay in enlarging the perceived scale of the social area without altering the layout, while integrating complex existing beams and ductwork. The sloped planes required precise control within 6 to 12 degrees, dynamic yet balanced. Even slight deviation would alter spatial perception. Repeated calibration at the junctions between ceiling and elevations ensured alignment between visual focus and lighting placement. Each adjustment sought equilibrium between order and tension.
Research: '12 Degrees' transforms angled ceilings into spatial syntax, guiding sightlines from social to private areas while integrating beams and ductwork. Dual-sided daylight and city views enhance openness. An island-like layout positions the sofa, kitchen island, and table as independent yet responsive elements. White sloped planes draw light inward, creating the sensation of moving aboard a vessel. Night lighting and fireplace glow trace contours, blending black and white rhythms.
Inspiration: Located on a mid-to-high floor with expansive views and abundant daylight, the residence sought transformation without overturning the existing layout. Titled '12 Degrees,' the project introduces slanted planes ranging from 6 to 12 degrees as visual catalysts within the space. The angle becomes more than a physical inclination; it represents a shift in perspective. When one is willing to tilt away from the established horizontal line, light and possibility begin to flow.
Project Duration: The project finished in Taiwan.
Operation Flow: The owner's most immediate impression is a sense of freedom. In the social area, the long table becomes the center of gatherings, seating easily adjusted while circulation remains unobstructed. In the private area, expansive sloped surfaces and floor-to-ceiling windows create a calm backdrop, with sightlines shifting alongside natural light. The space accommodates both lively social moments and quiet contemplation, like a flexible stage where daily rhythms adapt to the angle of inclination.
