Founding partners Li Chung (Sandi) Pei and Chien Chung (Didi) Pei



PEI Architects is dedicated to design excellence in the creation of architecture that serves and enriches people and their environments. Founding partners Chien Chung (Didi) Pei and Li Chung (Sandi) Pei learned from their father, world-renowned architect I. M. Pei, the exacting standards, craftsmanship, and social commitment required for buildings of timeless distinction. Pei Partnership Architects, founded in 1990, was renamed PEI Architects in 2019 to better recognize the team of talented men and women who contribute to the firm’s many achievements.
贝氏建筑事务所致力于设计卓越的建筑,以建筑为载体来服务和丰富人们的生活与环境。创始合伙人贝礼中(Sandi)和贝建中(Didi),继承了其父——世界著名建筑大师贝聿铭先生对永恒、卓越的建筑所倡导的严格标准、精湛工艺和社会承诺。贝氏合伙制建筑师事务所(Pei Partnership Architects)成立于1990年,为更好地彰显为公司作出杰出贡献的人才团队,2019年公司改名为贝氏建筑事务所(PEI Architects)。

The accumulated knowledge and experience of PEI Architects has enabled the successful completion of numerous buildings around the world. All are based on our foundational ethos: “Respect for the past and responsiveness to present needs in the pursuit of enduring architecture.”

PEI specializes in architecture, master planning, restoration, and interior design for high-profile projects, both very large and small. Its body of work includes high-rise residential towers, healthcare facilities, institutional buildings, museums, and corporate headquarters, as well as urban master plans and waterfront parks. The firm’s international body of work includes projects in the United States, Africa, Asia, Brazil, Canada, Europe, Mexico, and the Middle East.
PEI Architects’ approach to design starts with a thorough understanding of the uniqueness of each project. Beyond the particulars of individual programs and building sites, we take into account larger physical and cultural contexts, always striving to meet the needs of clients and building occupants in a way that also contributes to the civic realm. Our designs respond sustainably to the natural environment and aim for a positive impact on community development. PEI Architects’ goal is to produce physical environments that respond thoughtfully to society’s needs.
