About Merci Shop

Merci is a plant cafe built in a rural setting between two cities. The cafe is surrounded by roads and looks out over scenic countryside views. Wooden construction methods and advanced structural calculations allow extensive open ceilings. A central open atrium brings unity to the diverse spaces and fills the interior with natural light, creating a restful place at any time of day. The flooring is made from recycled coffee grounds solidified with cement, and the outer walls use natural materials. Local ingredients are served, supporting regional circulation and the surrounding community.

Merci Shop by YUMA SATO engages a vocabulary of refined modernist domesticity, positioning itself within trajectories of contemporary residential design that honor mid-century rationalist principles while addressing present-day concerns for environmental integration and spatial efficiency, the project appears to participate in ongoing explorations of how simplified formal language and restrained material palettes can generate architectural presence without resorting to ornamental elaboration, suggesting kinship with design approaches that privilege essential geometry, tectonic legibility, and calibrated proportional relationships, the compositional achievement of the work reveals itself through careful manipulation of massing where two distinct volumetric elements, each capped with traditional gabled or hipped roof profiles, interlock to create dynamic three-dimensional relationships that reward viewing from multiple vantage points, the fenestration strategy demonstrates sophisticated understanding of facade rhythm and scale modulation, particularly evident in the multi-light window assembly whose proportions and subdivision recall both industrial sash typologies and traditional residential casement logics, reinterpreted through contemporary minimal detailing, the chromatic decision to employ a near-monochromatic scheme of white render against black frames achieves multiple effects simultaneously, establishing crisp figure-ground definition, emphasizing geometric clarity, and providing neutral backdrop against which the surrounding landscape vegetation can register with heightened chromatic intensity, technically, the execution suggests attention to detail junctures, material transitions, and surface finish consistency, evidencing craft sensibility within contemporary construction methodologies, the integration of the structure within its landscape context demonstrates considered site response, where stone approach elements and layered planting beds mediate between natural grade and architectural threshold, creating gradual transition rather than abrupt boundary, thematically, the work appears to explore dwelling as an act of spatial definition and environmental framing, suggesting that domestic architecture serves both as shelter and as perceptual apparatus through which inhabitants experience their surroundings, the restrained aesthetic language may evoke philosophical positions regarding sufficiency, essentialism, and the capacity of simple means to generate rich experiential effects, the project potentially references vernacular building traditions that employed limited material vocabularies while achieving durable beauty through proportional refinement and contextual sensitivity, simultaneously, the work participates in contemporary discourse around sustainable residential design where thermal mass, natural ventilation potential, and passive environmental strategies inform formal decisions, the interplay between solid white walls and transparent glazed openings suggests intentional choreography of privacy and prospect, enclosure and exposure, interiority and exteriority, inviting consideration of how domestic architecture negotiates the complex relationships between individual, family, and community, between private retreat and social engagement, one might observe how the building's presence within its landscape setting proposes a particular model of inhabitation, one that values clarity, restraint, and attentive relationship to place, encouraging viewers to contemplate their own aspirations for domestic environments and the architectural qualities that support meaningful everyday existence.

Production Technology
The building was constructed using wooden construction methods. Advanced structural calculations were employed, making extensive use of open ceilings. The finishing materials included flooring made from recycled products of coffee grounds solidified with cement, and the outer walls used natural materials, resulting in a sustainable building.
Project Duration
We will continue to expand, starting with Okayama City in 2024. We aim to open multiple stores in the future.
Operation Flow
This building is a cafe open to the local community, and a space that aims to promote local circulation. It aims to be an indigenous land that uses local ingredients. It also has an eye on inbound tourism, as a place where people can enjoy sightseeing at traditional Japanese facilities that are a tourist resource for the region.
Research
In this architecture, the most important thing is a space for creating a new and nostalgic future that blends in with the community. We aimed for a space that maximizes the goodness of the area while being able to design for the future.
Inspiration
The idea was to build a peaceful structure in the countryside that connects the two cities.
Amidst the aging population and depopulation, it was crucial to support the local cycle and create a landscape loved by the community.
