Single Origin Store Chiangmai adapts house into micro roastery

 

Located in the San Phisuea district of Chiang Mai, Thailand, Single Origin Store Chiangmai is an adaptive reuse project designed by FLAT12x. The scheme converts an existing residential building into a functioning micro roastery for the coffee brand, expanding upon design principles first established in its flagship location near Chiang Mai’s Phae Gate.

 

The project emphasizes locality and material authenticity, integrating the structure with its natural context. The architectural form is kept low and linear, with deep roof overhangs that provide shade and protection from seasonal rain. A combination of large openings and passive design strategies enables cross-ventilation and visual continuity with the surrounding garden. The roof’s pitch and orientation are designed to minimize solar gain while allowing consistent natural illumination. Locally sourced materials are used throughout the project to reduce environmental impact and reinforce connections to regional craft traditions. Neutral finishes, ceramic tile textures, and tactile surface treatments define the café’s interior palette.

FLAT12x constructs custom coffee bar from local hardwood

 

Inside, a custom-built coffee bar constructed from local hardwood anchors the main space. A stepped-down floorplate introduces a sunken seating area, where coffee beans are used as ground cover beneath the stairs, creating both a sensory and visual reference to the store’s function. The architects at FLAT12x arrange this configuration to enhance spatial layering, promoting fluid movement between different zones for communal and individual activities. Seating is arranged to support various modes of use, including informal reading, tasting sessions, and small group interaction. Natural and artificial lighting is calibrated to shift the ambiance throughout the day, drawing attention to the material finishes and creating a responsive interior atmosphere. The design of Single Origin Store Chiangmai creates a space that supports the brand’s focus on origin, process, and craft through its architectural language.
