OMA's Shohei Shigematsu on New Museum Addition as Infrastructure

architecture-design · 2026-06-25

OMA partner Shohei Shigematsu discusses the firm's new addition to the New Museum in New York, which opened in March 2025. Designed with Rem Koolhaas, the angular companion building doubles exhibition capacity and redefines the institution's urban relationship. Shigematsu describes the project as a 'pair' of distinct but connected buildings: the original SANAA tower (2007) is vertical and introverted, while OMA's addition is horizontal and extraverted. Koolhaas called it a 'complement or counterpart' rather than a simple extension. The addition addresses the original building's constrained circulation and limited footprint.
