About the Company

John Portman & Associates, Inc. (PORTMAN) is an internationally recognized architectural and engineering firm with offices in Atlanta, Georgia and Shanghai, China. Established in 1953, PORTMAN has more than 55 years of expertise in designing hotels, universities, offices, trade marts, and mixed-use urban complexes. The firm’s diverse team of talented
professionals provides design services in architecture, master planning, programming, structural engineering, and project management. With the establishment of the Shanghai office in 1993, the firm became one of the first foreign architectural companies to do work in China.
The firm strives for an architecture that is more than just the design of a building, but rather a creation of a place for people, one that consciously uplifts a person through an enhancement of the human condition. Vision, creativity, and an entrepreneurial spirit are the fundamental factors that influence our design philosophy. Understanding human values and the human response to space, nature, and light is integral to the work. Nature and space – both external and internal – are indigenous to the firm’s architectural approach.
PORTMAN is renowned for innovative, responsive design solutions that are sensitive to the local culture and the context in which they exist. The firm aspires to integrate design excellence with economic feasibility. Development knowledge and ownership interests give PORTMAN designers a unique perspective on the economic aspects of the design process in resolving how to turn visionary ideas into practical realities. PORTMAN designs buildings that enhance the experience for those who use them, while being a sound investment for those who own and operate them.
