POPA combines simplicity with innovation, across scales ranging from master plans to buildings, interiors, and products. Themes we actively pursue are generosity, versatility, passive climate control through siting and materials, and smart interactions of new, old, and possible. We prefer appropriate technology over only the latest. Clear and responsive designs made through collaboration are a constant goal.

POPA is directed by Casey Mack, RA, LEED AP. After completing his M.Arch at Columbia, Mack worked with the Office for Metropolitan Architecture in Hong Kong and New York. He has taught urban design at the New York Institute of Technology and Passivhaus housing at Parsons School of Constructed Environments. Currently he is writing the book Digesting Metabolism: Artificial Land in Japan 1954-2202.
