OHArchitecture Converts a Kyoto Wholesale Dormitory into a Hotel Where Guests Live Among Artists

Kyoto's Tanba district sits just south of the main station, a grid of wholesale food markets where produce arrives before dawn and the architecture is bluntly functional: concrete frames, deep floor plates, big volumes. A former employee dormitory for market workers stood here for decades, five stories of raw concrete that nobody would have mistaken for a cultural destination. OHArchitecture, led by Kosuke Okuda and Tatsuya Horii, saw exactly that potential. In 2019 they completed KAGANHOTEL, a 2,021 square meter conversion that layers a hostel, an artist residency for up to 20 creators, gallery and studio space, and five luxury suites into a single building, turning the old warehouse into a place where art is made, shown, sold, and slept beside.

What makes KAGANHOTEL genuinely interesting is not the art hotel label, which has become a branding cliché. It is the spatial logic that OHArchitecture borrowed from the surrounding market buildings. Wholesale warehouses in Tanba use a "hanging box" construction: offices and storage units are suspended within big open volumes, leaving the ground level free for loading and sorting. OHArchitecture adopted this principle literally, inserting white painted volumes into the existing concrete shell so that the space beneath each box can shift between gallery, studio, and café without touching the structure above. The hotel is less a renovation than a parasitic insertion, and the tension between the old concrete host and its clean white guests is what gives every floor its energy.

The Ground Floor as Public Threshold

The entrance sequence sets the tone immediately. A double-height atrium greets visitors with exposed concrete beams overhead and a central glazed entrance that floods the mortar-troweled floor with daylight. The scale here is deliberately warehouse-like: the relatively high ceiling of the first floor was preserved rather than subdivided, so arriving feels more like entering a market hall than a lobby. Corrugated metal panels flank the glass doors, a nod to the industrial vernacular of the surrounding district.

Glass railings on the mezzanine level expose the suspended white volumes above, making the hanging box concept visible from the moment you walk in. This ground floor doubles as gallery and studio, with AEP-painted walls ready to receive rotating exhibitions. It is a genuinely public space in a building type that usually locks everything behind a reception desk.

Suspended Volumes and Exposed Structure

The central circulation spine reveals the project's defining move. White volumes hang within the concrete frame, their clean surfaces contrasting sharply with the rough existing structure left deliberately exposed and sealed with clear paint. The effect is surgical: you can read exactly where the old building ends and the new insertion begins. Undulating fabric ceilings and exposed ductwork on the staircase landings reinforce the industrial character without pretending the building is something it was not.

OHArchitecture treated the existing concrete columns and beams as the primary architectural expression, applying only a clear coating rather than cladding or rendering them. The structural grid becomes a kind of gallery framework in its own right, with each bay offering a different view through the depth of the building. Fixed fittings at the base of each suspended box allow the spaces beneath to be configured freely, a detail borrowed directly from the stacking logic of the wholesale market next door.

Guest Rooms as Art Spaces

On the upper floors, the guest rooms strip hospitality down to essentials. Lauan plywood furniture with a clear paint finish, timber bed frames, and wood flooring in the long-term artist rooms establish a warm material baseline against the ever-present concrete ceilings. The fifth-floor suites each contain an "art space" painted white, effectively turning a portion of the guest room into a gallery wall where resident artists' work can be displayed or sold.

The rounded-corner windows are a subtle but effective detail. They soften the otherwise blunt concrete openings and frame views of the Tanba district in a way that feels almost photographic. A white partition wall between rooms on the upper level allows visual connection through to adjacent spaces, reinforcing the communal ethos of the building. These are not hotel rooms designed for privacy and isolation; they are rooms designed to make you aware that you are living inside a creative community.

Material Honesty and Craft Details

The corridors compress the experience. Narrow passages with concrete floors, timber wall panels, and exposed conduit lit by copper-plated steel sconces create an atmosphere closer to a submarine or a backstage corridor than a hotel hallway. A wall-mounted room number plaque with a bare clear bulb is the kind of small gesture that communicates the project's values: nothing is hidden, nothing is decorative for its own sake.

Even the bathrooms follow this logic. The compact wet room with its freestanding white tub, wall-mounted shower fixture, and the same rounded-corner window found in the bedrooms manages to feel generous despite its tight dimensions. The material palette never deviates: concrete, white paint, timber, and copper. Consistency at this level of detail is what separates a serious conversion from a cosmetic facelift.

The Communal Ground

The open-plan ground level, with its glass-walled dining area and polished grey floor, functions as the social heart of the building. It is the point where overnight guests, resident artists, and visiting public overlap. The third floor houses ten single-occupancy rooms for artists with shared kitchen, living space, washroom, showers, and laundry, essentially a coliving floor embedded within a hotel. Below them, the second floor operates as a hostel with bunk-bed and shared-bed configurations. The programmatic stacking is deliberate: the further up you go, the more private and expensive the accommodation becomes, while the ground and basement levels remain the most open and productive.

This vertical gradient from public to private is the clearest evidence that OHArchitecture thought about KAGANHOTEL as a social system, not just a floor plan. The building does not simply accommodate artists; it forces productive friction between making and staying, between the permanence of a residency and the transience of a one-night booking.

Plans and Drawings

The six-level floor plan set confirms the programmatic clarity visible in the built work. The basement studio and warehouse level occupies the full footprint. The ground floor keeps its plan open with minimal partitions, while the upper floors progressively subdivide into smaller units as the program shifts from dormitory to single rooms to suites. Stair cores remain consistent, and the structural grid of the original warehouse is legible on every level, evidence that the conversion respected the existing column rhythm rather than fighting it.

Why This Project Matters

KAGANHOTEL is a case study in how adaptive reuse can do more than preserve a building's shell. OHArchitecture preserved the spatial logic of Kyoto's wholesale market district and repurposed it as an organizational principle for a completely different program. The hanging box concept is not metaphorical; it is a literal construction strategy that creates flexible, art-ready spaces within an unforgiving concrete frame. That specificity to site and context is what lifts the project above the growing field of generic "creative hotels" around the world.

The more important contribution may be programmatic. By embedding a funded artist residency for 20 creators inside a revenue-generating hotel, the project creates an economic model where hospitality subsidizes cultural production. Guests pay to sleep in a building where art is being made around them; artists get affordable live-work space in a city where rents are climbing. The architecture makes that transaction legible and, at its best, genuinely exciting. That combination of spatial intelligence and economic pragmatism is worth paying attention to.
