S M L XL

S,M,L,XL showcases a curated collection of groundbreaking design endeavors by the Dutch firm Office for Metropolitan Architecture (O.M.A.) and its celebrated founder, Rem Koolhaas, spanning its initial two decades. Collaborating with designer Bruce Mau, this publication serves as a visual and textual symphony, interweaving architectural projects, photographs, sketches, personal reflections, and critical essays on modern architecture and society.

Structured around its title, the book organizes projects and essays according to scale, with Small and Medium sections addressing themes from the domestic to the public realm, while Large delves into what Koolhaas terms “the architecture of Bigness.” The Extra-Large segment explores urban-scale projects alongside the seminal essay “What Ever Happened to Urbanism?” and other reflections on contemporary urban life.

Throughout its pages, the book introduces a lexicon of Koolhaasian language—a playful compilation of definitions, commentaries, and quotes drawn from diverse literary, cultural, artistic, and architectural sources—adding layers of depth and meaning to the narrative.
