GRIDFORM is an Istanbul based interior design studio founded by Mercan Tara Sisman. Rooted in her background in industrial and architectural design, Mercan approaches interiors with the precision of product design, where functionality and storytelling shape every decision. Through a restrained palette of tactile materials and carefully orchestrated light, the studio creates immersive spaces defined by atmosphere rather than ornament. GRIDFORM believes every space should hold a narrative, one that is experienced rather than explained. The studio’s work extends from Istanbul to Los Angeles and New York.

Founded in 2026, GRIDFORM is the natural continuation of Mercan's independent interior design practice, whose work has been published since 2018.
