Musical Architecture Connects Two Homes in Tokyo Suburbs
Slur House blends traditional and modern design through light and space.
1An Architectural Slur
Slur House is an annex added to a 15-year-old family home in Tokyo's suburbs. Led by Yohei Ikai, the team drew inspiration from the musical 'slur' concept to harmoniously connect two structures. The main house's square plan, pointed roof, and white exterior were reflected in the new addition. The measured gap between the two buildings accommodates the family's evolving needs while maintaining visual continuity.
2Spaces Dancing with Light
The annex's ridge beam was shifted toward the main house to create higher ceilings. A high-level side window captures sunlight reflected from the main house's white wall. Morning reflections create a dynamic indirect lighting source in the annex. The gap between structures thus serves dual purposes: spatial separation and a light-channeling device, transforming what was once the main house's rear into a light-reflecting surface.
3Smart Interior Solutions
The 30-square-meter annex features two lofts, freestanding columns, and circulation paths. Windows facing the south garden are positioned according to residents' activities. Collaborating with textile designer some/to, gradient curtains were created to connect differently sized windows. The curtains' changing tones and transparency throughout the day continuously alter indoor-outdoor relationships, creating a living connection with the garden.
4Family-Crafted Design Elements
The desk and table were co-developed by the architect and family, who assembled and painted the pieces themselves. Lauan plywood used in furniture matches ceiling applications, ensuring material continuity. Digital fabrication allowed precise cutting from just three 21mm-thick boards, minimizing waste while producing custom furniture fully integrated with the annex's spatial system. This approach reduced costs without compromising design quality.
5Rethinking Suburban Architecture
The project addresses Tokyo's fragmented suburban landscape of small-scale housing developments. It proposes a method to reorganize existing residential sites as family needs evolve. The 'slur'-like arrangement between structures maintains visual and spatial proximity while supporting individual independence. This innovative approach demonstrates how architectural additions can respect original designs while meeting contemporary living requirements.
6Material and Light Dialogues
Lauan plywood creates a consistent material language from furniture to ceiling. Pink gradient curtains complement interior wood finishes and garden greenery. From the entrance, sightlines extend toward three south-facing windows, each responding to different activities within the compact space. Every design element serves multiple purposes, maximizing functionality in the limited 30-square-meter area.
7Richness in Compact Spaces
Two lofts, freestanding columns, and looping circulation paths create spatial richness within 30 square meters. The ladder to the lofts and high window facing the main house add vertical dimension. Evening views from the south garden reveal harmonious connectivity between structures. Through thoughtful design solutions, the small annex offers diverse spatial experiences typically found in much larger homes.
8Sustainable Personalization
Slur House combines sustainable design principles with family-centric customization. Digital fabrication maximized material efficiency, while DIY furniture added personal touches. The project serves as an inspirational example for transforming existing suburban homes. By integrating architecture, music, and light concepts, it delivers a unique living experience that respects tradition while embracing modern design innovation.
