Architectkidd, a Bangkok-based studio, redirects attention in Southeast Asia’s fast-paced construction industry by focusing on sandwash cement rather than the usual concrete and steel. Through recent explorations, the studio challenges perceptions and proves that this modest material still holds relevance, especially in interior applications.
Sandwash cement, often confused with exposed aggregate concrete, consists of small stones mixed into cement. Once poured, the top layer of cement is washed off to reveal the underlying stones, producing a textured surface with natural variation. In past decades, sandwash saw widespread use across Thailand, especially in homes, temples, and schools. Though many associate it with worn-out public areas or neglected structures, Architectkidd sees potential where others see decline.
Made by Hand, Designed with Intent
The process of creating sandwash cement still relies on manual labor and local expertise. It’s typically mixed and applied on-site, using basic tools and accessible materials. This localized production method reduces energy use and lowers costs, making it more resource-efficient compared to industrial finishes. While it may lack the polish of terrazzo or the prestige of imported stone, sandwash allows a similar degree of customization. Designers can select different stones and textures depending on the spatial concept, achieving surfaces that feel both raw and deliberate.
Texture Meets Form
Architectkidd focuses not only on texture but also on form. Unlike rigid materials like brick or cut stone, sandwash cement flows easily into curved molds. This pliability enables the creation of soft edges and continuous forms that feel embedded into the architecture. Whether applied to walls, staircases, or countertops, it introduces visual depth and tactile interest without overpowering the rest of the design.
Natural Yet Defined
What sets sandwash apart lies in its dual nature: it feels both handmade and structural. It reflects the labor that goes into it, yet doesn’t appear crude. By adjusting ratios of aggregate to cement, the final surface can express different densities and finishes, from coarse and rugged to relatively smooth and refined. These qualities open up a range of possibilities for architects interested in natural finishes without excessive ornamentation.
Architectkidd’s work with sandwash is less about nostalgia and more about re-evaluation. By experimenting with this overlooked material, the studio proposes a renewed role for it in contemporary design.
