Boston Society of Architects

The Boston Society of Architects is the professional association for architects and designers in eastern Massachusetts and one of the oldest and largest chapters of the American Institute of Architects. With more than 4,500 members, it is the second-largest AIA chapter. It supports architects at every career stage, from students to Fellows, with continuing education, conferences, workshops, and advocacy at the local, state, and national level.

Founded in 1867, the organization has long served as a gathering place for people who see architecture as a force for good. It works alongside Architecture in Common, its charitable arm formerly called the BSA Foundation, which connects the profession with the public through events, exhibitions, and youth education. Together they push for a more equitable, resilient, and livable Boston, centering community voices and treating design literacy as a way for residents to shape their neighborhoods.
