Plan 21 Completes Dual-Family Residence in Toyama with Integrated Courtyard
Japanese studio Plan 21 has designed a unique two-family home in Toyama City, featuring two distinct structures connected by a central courtyard, fostering a sense of shared living while maintaining individual privacy.


In Toyama City, Japan, architectural studio Plan 21 has realized the Machikado Project, a distinctive residential development designed for two families. The project comprises two separate buildings, thoughtfully arranged around a central courtyard to create a cohesive living environment that respects individual privacy.
One building serves as the residence for the mother, designed as a single-story structure. Adjacent to this, a two-story building houses the son and his wife. Despite their distinct layouts and footprints, the two structures are unified by the shared courtyard and are presented visually as a single architectural entity. This design approach fosters a sense of community and connection between the generations while allowing for independent living.
Por que importa
The integration of the courtyard is central to the project’s success. It acts not only as a visual and physical link between the two homes but also as a source of natural light and ventilation for both. This outdoor space likely serves as a private oasis for the residents, offering opportunities for relaxation and interaction within the property. The architects’ intention to make the two buildings appear as one suggests a careful consideration of aesthetic harmony and neighborhood integration.

Contexto
This project by Plan 21 offers an interesting case study in multi-generational housing solutions. In contexts where family ties remain strong, designs that facilitate close proximity while acknowledging the need for personal space are increasingly valuable. The Machikado Project’s success lies in its ability to balance these often-competing demands through thoughtful spatial planning and a sensitive architectural response. The use of wood as a primary material likely contributes to a warm and inviting atmosphere, common in Japanese residential architecture.
The strategic placement of the two buildings around the courtyard not only enhances the living experience for the occupants but also potentially influences the microclimate and aesthetic of the site. Such integrated courtyard designs are a hallmark of architectural approaches that prioritize well-being and community within a private dwelling. For readers interested in innovative residential typologies and contemporary Japanese architecture, the Machikado Project provides a compelling example of how form and function can be harmoniously combined to meet the needs of modern families.
