MUJI Designs a Micro-House and DIYs the Objects to Fill It

ByMyProperty Life

In a world that moves fast (and only seems to be speeding up), MUJI’s latest project feels like a deep breath. At Milan Design Week 2025, the brand teamed up with Studio 5∙5 to debut MUJI MUJI 5∙5 a modular micro-architecture house and a suite of clever DIY creations, all crafted from everyday MUJI products. Together, they created a blueprint for a downshifted life – one that favors calm, creativity, and a little less stuff.

Designed with Japan’s tradition of modest, modular living in mind, the micro Manifesto House embraces flexibility, sustainability, and calm. Built from prefabricated modules, it can be configured to the perfect size, from a one-person retreat to a family weekend getaway. Eco-conscious touches, like recycled textiles for insulation, a white roof that reduces heat absorption and collects rainwater, and a raised structure with an open upper section for passive cooling, ensure the home treads lightly – and thoughtfully – on its environment.

The Manifesto House unfolds across six flexible modules, each designed with simplicity and purpose.

The Genkan marks the entrance, with a bench that doubles as shoe storage – a must in Japan, where it’s customary to remove your shoes before entering – and a coat rack crafted from repurposed bottles. The Ofuro module, dedicated to hygiene and well-being, features a reinterpreted Shoji sliding partition and a traditional Japanese soaking bath.

Tatami module

The Tatami module offers a foldable sleeping area that maximizes every square inch. And outside, a Niwa garden nods to Japan’s courtyard gardens, offering a place to grow food, meditate, or simply stay still.

In the spirit of doing more with less, MUJI and Studio 5∙5 also introduced MUJI MUJI 5∙5, a collection of DIY creations that transform existing products into new objects for daily living. With just a few tweaks, familiar MUJI products turn into entirely new creations: a birdhouse built from a bookend and drawer, a hollow shelf fashioned from bamboo boxes, even a gong made from a measuring bowl and coffee spoon.

More than a showcase of clever design, the Manifesto House and MUJI MUJI collection embody a shared belief between MUJI and Studio 5∙5: that true living isn’t about accumulating more, but about choosing well. Every object, every space, is a quiet affirmation of shaping a life with intention – focusing on what is essential, what is versatile, and what will truly endure. It’s proof that intentional design – and a little DIY creativity – can go a long way.

  • Ravoli Drive Residence

    Sited on a site slightly under an acre in the heart of the Pacific Palisades area of Los Angeles, the site for this estate residence descends over thirty feet from top to bottom. Narrow at the street and widening toward the rear, the building was designed to appear as a very private single story structure from the street and expand as the house moves into the site. At just under 14,000 sq. ft. the house was conceived of as a California Modernist Estate the building utilizes the site slope and widening to create a wing typology each reaching into the site to capture garden spaces, set up views and account for service amenities. Designed for peak privacy to the street, there are a series of site walls and fencing that define the property edge. After passing through the gate, the entry to the house is through a descending Entry Garden with water feature with a view through the house to the slopes of Will Rodgers State Park beyond. Shaped as a modified T, the wings of the house extend into the landscape creating separate wings dedicated to the elaborate programming of the building. Containing formal spaces for Entry, Living and Dining the house also offers a large entertainment style kitchen, Large Family Room, Library, 16 person Theater, Wine Cellar, Gym with Spa Bath including Sauna and Steam Room, secondary winter closets, dedicated two bedroom Guest House as well as six bedrooms including a Master Suite over 1,500 square feet with his and hers baths and closets as well as a garage for seven plus additional carport parking for three. All of this is balanced with a series of large exterior decks, patios and pool all wrapping around the stately eighty-foot tall Eucalyptus tree, which served as the aesthetic basis for the materiality of the building. Balancing the solidity of the extensive board form concrete walls is an expansive use of glass and the warmth of stained wood siding throughout the building. The remainder of the building is wrapped in integral colored steel troweled stucco. This palette is based on the colors and tones of the tree that is the center of the garden. Passing materials from the interior to the exterior, doors disappearing into internal pockets and flooring extending onto the decks and patios all help to create a seamless relationship for the interior to the exterior, house to land. This relationship realizes a full use of the site for its entire acre site.
