THE FACETS is a thoughtful renovation and extension of a café nestled within the grounds of a renowned gemstone shop in San Kamphaeng, Chiang Mai. The design centers on expressing the variety and allure of gemstones through architectural language—crafting a space that is distinctive, sensorially rich, and deeply connected to its cultural context.

Architecture: From Crystal Clarity to Iridescent Facades
The project unfolds in two primary volumes:
-
Renovated Volume: The existing building is transformed into a crystal-like form by cladding it with clear glass blocks in two sizes arranged in an alternating pattern. This subtle white, silver, and transparent palette allows the interior to glow softly at night—evoking the radiance of a gemstone resting in a display case.
-
New Addition: Inspired by the multifaceted geometry of a diamond, the new extension features a steel structural frame enveloped in acrylic panels coated with dichroic film. These panels shimmer with iridescence, their colors subtly shifting as the sun moves—turning the building’s façade into a living jewel that dances with light.

Interior Design: Layers of Lightness and Sparkle
Inside, the design tells the story of a gemstone’s journey before polishing—still unrefined and buried in earth. Wall elements mimic stone caves, textured with surfaces recalling geological strata. The interior palette is predominantly white, accented with reflective materials to symbolize crystalline purity.
The sharply faceted counter bar is clad in mirrored aluminum, casting luminous reflections onto the floor that conjure the brilliance of diamonds. Above, delicate acrylic panels hang suspended from the ceiling, swaying gently and catching light at ever-changing angles.
Furniture takes cues from raw stone shapes, featuring glossy laminates and colored acrylics inspired by specific gem hues. This infusion of vibrant yet transparent elements maintains a sense of lightness and fluidity throughout the café.

Landscape: A Dialogue Between Nature and Craft
The garden design embraces simplicity and serenity. Lush green plants soften the precise geometry of the building, while a free-form pond snakes through outdoor seating areas, mirroring and animating the architecture’s changing light.
Locally crafted materials enrich the setting, notably handmade clay bricks used for gently curving walls. These artisanal touches add warmth and cultural continuity, bridging contemporary expression with traditional craftsmanship.
Conclusion: More Than a Café—A Living Gem
THE FACETS transcends mere imitation of gemstones; it captures their essence through form, light, and texture, translating these qualities into an immersive emotional and spatial experience. More than a coffee shop, it stands as a living gem at the heart of San Kamphaeng, where architecture itself becomes a reflection of place, light, and cultural identity.
