21A Interiors
INTERIOR DESIGNer
Based in Istanbul and working internationally, 21A Interiors designs residential and retail spaces with an emphasis on proportion, circulation, and material integrity. Led by Tuvana Serdaroğlu, the studio approaches each project from the inside out - starting with how a space functions and flows, then shaping the atmosphere through restrained material choices, tactile finishes, and carefully considered lighting. Understated but never minimal, 21A’s interiors are defined by clarity, comfort, and a sense of timeless balance.

Some studios decorate. 21A Interiors composes. Calm proportions, refined restraint, and a sensual material palette that makes you want to run your hand along every surface. It’s the kind of space that doesn’t shout, it just wins.
