Retractable Living in a Compact Washitsu with Hydraulic Eaves

Project in-detail

A compact washitsu elevated on tatami flooring features retractable furniture and hydraulic eaves, enabling a flexible living space for a young professional couple.
5 key facts about this project
01
A multifunctional washitsu serves as the primary living space.
02
Hydraulic eaves provide adaptability to weather conditions.
03
Raised tatami flooring allows for hidden storage beneath.
04
Retractable furniture maximizes the use of limited space.
05
Integrated systems support off-grid living capabilities.

The design showcases a microhome built for a young professional couple, focusing on the blend of traditional Japanese living with modern requirements. Located in a suburban setting, the home covers an area of 7.5 tsubo (24.8 m²), effectively integrating various functions while retaining a deep cultural connection. The concept of 二人暮らし (futarigurashi), meaning "two people living together," emphasizes a thoughtful balance between practicality and heritage.

Design Elements

The plan includes vital areas such as an entrance, kitchen, washitsu, bathroom, workspace, and a retractable daybed. The washitsu stands out as the main living space, redefining its usual role as a secondary area. Each section is designed to foster interactions and personal activities, allowing for smooth transitions between work and relaxation.



Functional Integration

A significant detail is the raised tatami flooring that honors tradition while providing extra storage beneath. This layout supports the use of retractable furniture, enhancing the livability of the space. Integrated desks and storage in partition walls make efficient use of limited space, accommodating the daily needs of the couple.



Sustainability Features

Sustainability plays an important role, with photovoltaic panels, batteries, an inverter, a water collection system, a boiler, and air conditioning incorporated into the design. These elements work together to allow for off-grid living, minimizing the ecological footprint while maximizing independence. The arrangement of these systems supports a responsible and environmentally friendly way of living.



Spatial Dynamics

Careful design choices promote natural light and ventilation throughout the home. Morning sunlight brightens the space, creating a refreshing atmosphere, while afternoon light provides a conducive environment for work. In the evening, a dining table allows for comfortable meals, protected from the harshness of direct sunlight, promoting social gatherings.



The combination of traditional and modern elements continues with the hydraulic eaves and folding features, which create adaptable spaces that meet the needs of the occupants while maintaining a connection to the outside world.
