The 40-square-meter apartment in Tokyo’s Ogikubo neighborhood demonstrates how clever design can transform confined spaces into areas that feel open and adaptable. Architect Shinji Sonoda took a ground-floor unit originally divided into two enclosed rooms and converted it into an open-plan home for a daughter returning to care for her aging parents living upstairs. The removal of walls allows natural light to flood in from three directions, including the adjacent Japanese garden.
The design relies on wire systems supplied by the client’s parents’ company, Arakawa Giken Kogyo, to create a flexible living environment. Shelves, cabinetry, and room dividers hang from these wires, eliminating the sense of heaviness and allowing the space to be reconfigured as needed. Triangular, trapezoidal, and curved shapes define different functional zones without the need for rigid walls, while slight variations in floor elevation help distinguish living and sleeping areas.
Five standout elements define the apartment’s serene and adaptable nature. The first is timber joinery suspended by wire, combining natural warmth with the precision of the industrial system. A piece of timber salvaged from the property’s original tree serves as an anchor for one cabinet, linking the design to the site’s history while keeping the layout adjustable.
The kitchen occupies the apartment’s central position, constructed from stainless steel for its reflective qualities and ease of cleaning. Triangular wall panels enhance the room’s brightness by reflecting light deeper inside, reinforcing the geometric theme. Above the kitchen, a large circular shelf hangs from the wires, softening the sharp angles with its organic curves. Integrated lighting beneath the shelf creates a warm glow across the stainless steel surfaces, blending practicality with ambiance.
Shoji screens blend privacy with openness
Shoji screens serve both functional and aesthetic purposes. At the entrance, a custom-made shoji door marks the transition into the private living space while still allowing light to pass through. Inside, a second screen separates the living and sleeping areas, concealing the bed without creating a closed-off space. The translucent paper maintains privacy while upholding the design’s emphasis on openness, a characteristic feature of Japanese architecture.
The bedroom is positioned in a quieter corner, accessible by a single step up from the main floor. Finished in carpet with rounded edges, simply stepping up marks a new zone within the apartment, without the need for a wall or door. The sleeping side of the partition – clad in deep blue tiles – deepens the sense of calm and enclosure. For storage, a full-length wardrobe spans the wall, with upper shelves suspended once more from the ceiling by wire.
What makes this apartment truly effective is its rejection of permanent fixtures. Instead of fixed partitions or solid walls, the design uses suspended elements, translucent screens, and subtle floor changes to create a home that feels both open and personal. These choices allow the space to adapt to the needs of its residents while remaining connected to its surroundings. The result is an environment that grows with its inhabitants, maintaining a sense of openness and flexibility.
Design bridges family bonds in multigenerational living
Such designs hold particular value for families managing multigenerational living arrangements. A daughter caring for elderly parents can enjoy privacy and autonomy within the same household, while the open layout encourages interaction. The wire systems, beyond their practical use, carry emotional significance, linking the apartment’s design to the family’s background and the land it occupies.
Every detail, from the suspended kitchen shelf to the shoji screens, fulfills a purpose beyond its appearance, reinforcing the apartment’s central concept: even in limited space, intentional design can produce a home that feels expansive and welcoming.
The project’s success extends beyond its visual appeal. The wire-supported elements reduce the need for heavy construction, making the space easier to modify in the future. The use of natural materials and salvaged timber connects the interior to its environment, while the careful balance of open and private areas addresses the practical needs of multigenerational households. This approach proves that thoughtful design can maximize both functionality and emotional resonance in small living spaces.
Critics praise flexibility over fixed compact living norms
Architectural critics have noted how the apartment challenges conventional assumptions about compact living. By prioritizing flexibility over fixed structures, Sonoda’s design demonstrates that limited square footage need not compromise comfort or adaptability. The integration of personal history—through the salvaged timber and the family-owned wire systems, adds depth to the space, making it more than just a functional solution. Instead, it becomes a living reflection of the family’s values and daily routines.
Future projects in similar urban settings could draw inspiration from this model. The combination of lightweight materials, modular systems, and culturally informed design choices offers a sustainable path for creating livable spaces in densely populated areas. For families facing the challenges of multigenerational coexistence, this apartment serves as a practical example of how thoughtful planning can harmonize privacy, connection, and adaptability within constrained boundaries.
The Ogikubo apartment’s most compelling feature remains its ability to evolve alongside its residents. Unlike traditional fixed layouts, this design accommodates changing needs without major renovations. The wire-based systems allow for easy reconfiguration, ensuring the space remains relevant as family relationships shift. This adaptability, combined with the careful use of light and materials, makes the apartment a model for modern, responsive living in urban environments.
