Pair of R. Koolhaas Door Handles

The door handle designed by Rem Koolhaas translates his architectural language to the scale of an object, combining structure and modularity. This conceptual creation deliberately separates the lever from the base, which fit together mechanically like two architectural elements in dialogue. This innovative design breaks free from traditional conventions, paving the way for a new, bold, and functional aesthetic.

This pair of door handles is intended for:

on newer doors (mortise locks);
for doors between 38 mm and 40 mm thick (standard thickness). This handle comes with a 7 mm square spindle and the adapters needed for installation.

Description

R. Koolhaas – The Graphic Doorknob

The R. Koolhaas door handle, designed in 2015 by Rem Koolhaas—a leading figure in contemporary architecture and founder of the OMA firm—subtly translates the fundamental principles of his architectural language to the scale of an object. Known for his radical projects and his reflections on structure, modularity, and the relationship between form and function, Koolhaas presents here a doorknob that is not merely a functional accessory, but a miniaturized manifesto of his conceptual approach.

This door handle stands out for its visibly disjointed construction: the lever and the base are not fused together but are deliberately assembled mechanically, almost as if two architectural elements were engaging in a dialogue within the space. This formal separation reflects a desire to free the handle’s design from conventional constraints, opening the door to new aesthetic and technical explorations.

The handle retains a clean, graphic, almost austere silhouette, where every detail is designed to reflect a minimalist approach and formal purity. The choice of solid brass, crafted with high-end finishes, anchors the object in a commitment to quality, while the modular nature of its design allows for visual variations depending on the context of use or stylistic preferences. The gap between the two parts, far from being merely decorative, reinforces this idea of openness—both physical and symbolic—by allowing light, space, and the imagination to flow through.

With this pair of door handles, Koolhaas does more than simply design a handle; he questions the object—its nature and its function—and offers a bold, resolutely architectural response to what an everyday detail might be.
