Pair of ABC R. Koolhaas Door Handles with Square Rosettes

ABC R. Koolhaas – the door handle with a raw yet elegant design

The ABC door handle set, designed in 2019 by world-renowned architect Rem Koolhaas, founder of the OMA firm, embodies a radical vision of design: a return to the essentials. True to his architectural approach, Koolhaas designed this handle as an archetypal form: a purely functional bar with a square cross-section, stripped of all superfluous ornamentation. This deliberate simplicity is not a default choice, but a conceptual stance: the handle becomes a miniature architectural object, revealing its presence through its geometric precision and the tension of its proportions.

Crafted from solid brass—a premium material with excellent mechanical properties—the ABC handle combines structural strength with a pleasing tactile feel. Its understated design serves as the perfect canvas for a wide range of refined finishes that subtly alter the visual perception of each room.

With the ABC handle, Koolhaas presents a universal design concept, intended to adapt to any setting: contemporary residential interiors, cultural spaces, or offices with clean lines. Minimalist yet expressive, it encapsulates the designer’s philosophy in a single, understated gesture: creating a dialogue between form and function, without ever sacrificing quality or intent.
