Old and new materials coexist without apology
In Iguchido, Osaka, two timber outbuildings that once offered shelter to those in need—and then fell silent for decades—have been given new life as Ichizu, a shared kitchen and community gathering space. Coil Kazuteru Matumura Architects chose neither demolition nor nostalgia, but something rarer: a careful conversation between what time had left behind and what the present requires. The project is the first step in a gradual reawakening of an entire inherited property, guided by the belief that old places deserve to be listened to before they are changed.
- Two timber structures, hidden behind a family home and overtaken by vegetation for decades, carried the weight of abandonment and a forgotten history of sheltering people in need.
- The risk of erasure was real—such buildings are routinely demolished rather than reconsidered—making the architects' decision to preserve rusted cladding and weathered surfaces a quiet act of resistance.
- New custom joinery, plywood, and mill-scale steel were introduced with precision, creating a working kitchen without silencing the materials that recorded the passage of time.
- The site now hosts three distinct but connected spaces—Ichizu, Wells Garden, and a vintage shop—each reactivated incrementally rather than through a single sweeping redevelopment.
- The project is landing as a model of restraint: a property that once sheltered the vulnerable now opens itself to the community one carefully considered space at a time.
On a property in Iguchido, Osaka, two small timber buildings spent decades hidden behind a family home, slowly consumed by weather and vegetation. They had once served as temporary housing arranged by the client's grandfather, but after his time, they fell into silence. The rusted steel cladding that covered them became an unintentional archive of neglect.
Coil Kazuteru Matumura Architects chose not to erase that archive. Instead of demolishing the structures or restoring them to some imagined earlier state, the firm let them speak their age while giving them new purpose. The result is Ichizu—a name meaning steadfast dedication—a shared kitchen and community gathering space that opened as the first phase of a broader effort to reactivate the entire inherited property.
The renovation is defined by restraint. Rusted corrugated steel cladding was preserved in place, while new elements—custom timber joinery, lauan plywood, stainless steel, and mill-scale steel—were introduced with care. Old and new materials coexist without apology, each acknowledging the other. The kitchen facilities and interior finishes were built to meet the demands of a working space while respecting the weathered character of what was already there.
The experience of moving through the property is itself part of the design. Visitors pass through layers—street-facing buildings, a parking area, an open field—before the two renovated structures reveal themselves at the rear. This sequence preserves the spatial depth of the site while drawing new activity into what had long been private ground.
Ichizu now operates alongside two other reactivated spaces: Wells Garden, a shared growing space in the field, and Tsuru no Negoto, a vintage and antiques shop in the renovated storehouse facing the street. Each functions independently for now, but a future kitchen near the main house is planned to connect them into a continuous flow of food, gardening, and communal life. The architects also developed a unified visual identity across all three spaces, giving the site a coherent presence.
What distinguishes this project is its refusal to resolve everything at once. By assigning new roles to existing buildings incrementally, and by treating rusted steel and weathered timber as materials to work with rather than problems to overcome, the team created something that honors the past while making genuine room for the future.
On a property in Iguchido, Osaka, two small timber buildings sat hidden behind a family home for decades, slowly surrendering to weather and neglect. They had once sheltered people in need—temporary housing arranged by the client's grandfather—but after his time, they fell silent. Vegetation crept across their surfaces. The rusted steel cladding that covered them became a record of abandonment.
Coil Kazuteru Matumura Architects saw something different in those structures. Rather than tear them down or restore them to some imagined earlier state, the firm chose to let them speak their age while giving them new purpose. The result is Ichizu, a shared kitchen and community gathering space that opened as the first phase of a larger effort to reactivate the entire inherited property. The name means steadfast dedication—a commitment to care for old buildings and adapt them for the future, one careful step at a time.
The renovation is a study in restraint. The architects preserved the rusted corrugated steel cladding, letting it remain visible as a physical record of time passing. New elements—custom timber joinery, lauan plywood, stainless steel, and mill-scale steel—were introduced with precision, creating a deliberate contrast between what was there and what is new. The doors, interior finishes, and kitchen facilities were all built using these materials, chosen to provide the durability and functionality a working kitchen demands while respecting the weathered character of the original structures. Old and new materials coexist without apology, each acknowledging the other.
The way visitors experience the site matters as much as the buildings themselves. The property stretches back from the street through layers: first the main house and a storehouse facing the road, then a parking area, then a field that extends toward the rear. The two renovated timber buildings emerge gradually as you move through this sequence, revealing themselves only after you have passed through the more public zones. This layered approach preserves the spatial depth of the site while introducing new activity into what had long been private ground.
Ichizu now functions as a shared kitchen where people can gather, cook, and rest while using the adjacent garden. But it is not the only new use on the property. The field has become Wells Garden, a shared growing space. The street-side storehouse has been lightly renovated and now operates as Tsuru no Negoto, a shop specializing in antiques and vintage clothing. Each space functions independently for now, but the architects and client have mapped a future where they connect—where food preparation, the garden, and communal activities flow across the entire property through an additional kitchen planned near the main house.
The project reflects a philosophy of incremental care rather than wholesale transformation. Instead of redeveloping the property as a single grand intervention, the team assigned new roles to existing buildings and landscape over time, allowing the site to evolve gradually. The client participated in the Ikeda Women's Network capacity-building program and received an IWN Challenge Grant, support that helped sustain this broader vision of reactivation. Studio coil Kazuteru Matumura Architects also developed the visual identities and logos for all three spaces—Ichizu, Wells Garden, and Tsuru no Negoto—creating a coherent visual language across the site.
What makes this project worth attention is not that it solved a problem in one gesture, but that it chose to listen to what was already there. The rusted steel cladding, the timber frames, the field, the sequence of spaces—these were not obstacles to overcome but materials to work with. By preserving them and introducing new uses with care, the architects created something that honors the past while making room for the future. The property that once sheltered people in need now opens itself to the community in a different way, one kitchen, one garden, one shop at a time.

The Hearth Conversation Another angle on the story
Why preserve the rust? Wouldn't new cladding have been cleaner, more practical?
The rust is the building's autobiography. It shows what happened here—decades of weather, use, abandonment. If you cover that up, you erase the story. The architects understood that the weathered surfaces are not failures to be hidden but evidence to be honored.
But doesn't mixing old rusted steel with new stainless steel create visual chaos?
No, it creates conversation. The contrast is intentional. When you see the new timber joinery next to the weathered original structure, you're not confused—you're aware of time. You understand that this building has a past and a present, and both matter.
The site is hidden behind the main house. How do you get people to use a community kitchen they can't see from the street?
That's the genius of the layered approach. You walk through the property, past the main house, past the storehouse, into the field. By the time you reach Ichizu, you've already been oriented to the site's geography. It's not hidden—it's revealed gradually. It feels like discovery.
Is this just one building, or is there a larger plan?
This is phase one. The field is now a shared garden. The storehouse became a vintage shop. Eventually there will be another kitchen near the main house to tie everything together. The property is being reactivated piece by piece, not all at once. That's what the name Ichizu means—steadfast dedication over time.
Who actually uses these spaces?
The client received support from the Ikeda Women's Network, so there's a community dimension built in from the start. It's not just a private renovation—it's a property being opened to neighbors and visitors. The shared kitchen and garden are designed for that public use.
