MUJI Prefabricated Houses

MUJI has launched two representative products in the field of prefabricated houses, namely 'MUJI no Ie' and 'MUJI 5.5 House', which respectively embody the combination of high durability and functional design with modularization and environmental protection concepts.

'MUJI no Ie': High Durability and Functional Design

With the theme of 'Nagaku Tsukaeru, Kaerareru' (Long-lasting and Flexible), 'MUJI no Ie' focuses on durability and spatial adaptability in its core design philosophy. Its standard configuration adopts 'Double Insulation' and 'Triple Glazing', significantly enhancing the building's thermal insulation performance, reducing energy consumption, and extending the building's service life. Indoor environmental simulation technology is applied to optimize the design of light, heat, and wind. For example, through precise calculations of building orientation, window layout, and ventilation paths, natural lighting and ventilation are maximized, reducing reliance on artificial lighting and air conditioning. In terms of spatial flexibility, a variable partition system allows users to adjust room functions according to their needs, such as merging or separating the living room and study to adapt to changes in family structure or living scenarios.

'MUJI 5.5 House': Modularization and Environmental Protection Concepts

In collaboration with Paris-based 5.5 Design Studio, the 'MUJI 5.5 House' focuses on modularization and resource recycling. The house consists of six interchangeable modules, each serving a specific function (such as sleeping, living, and storage). Users can add or remove modules or adjust the layout according to their needs, achieving efficient space utilization and personalized customization. The interior facility design fully embodies the 'ready-made lifestyle aesthetics'. For example, classic MUJI storage boxes are transformed into seats, and plastic basins are used as sinks, continuing the brand's simple and practical style while reducing resource waste through the reuse of old items. Additionally, the modular structure facilitates disassembly and reassembly, providing convenience for future house upgrades or relocations and further reinforcing the concept of sustainable living. Currently, this design is still in the conceptual stage, but the brand has indicated that it may be released to consumers, becoming a new member of the prefabricated house series.

MUJI's exploration of prefabricated houses not only enhances building performance through technological optimization but also responds to modern life's demands for flexibility and environmental protection through modular design, providing an innovative model for sustainable living.
