OA (Office of Architecture) is a New York City based architecture and design practice.  OA was established in 2012 on the premise that great spaces require the artful orchestration of bold vision and practical logistics; that ingenuity can emerge from the limits set by the hard realities of a problem; and that imagination and common sense need not be mutually exclusive.  OA engages each project with the design sensibility to envision the big idea and the professional savvy to realize its potential.
