The Office for Metropolitan Architecture is a Dutch architectural firm based in Rotterdam, founded in 1975 by Dutch architect Rem Koolhaas and Greek architect Elia Zenghelis, along with Madelon Vriesendorp and Zoe Zenghelis.
OMA is an international practice operating within the traditional boundaries of architecture and urbanism. AMO, a research and design studio, applies architectural thinking to domains beyond. OMA is led by eight partners – Rem Koolhaas, Ellen van Loon, Reinier de Graaf, Shohei
Shigematsu, Iyad Alsaka, Chris van Duijn, Jason Long, and Managing Partner-Architect David Gianotten – and maintains offices in Rotterdam, New York, Hong Kong, Doha, and Australia. OMA-designed buildings currently under construction are Taipei Performing Arts Centre, the renovation of Kaufhaus des Westens (KaDeWe) in Berlin,
The Factory in Manchester, and the CMG Qianhai Global Trade Center in Shenzhen.
