The Boston Society For Architecture (BSA/AIA) is committed to professional development for its members, advocacy on behalf of great design, and sharing an appreciation for the built environment with the public at large. Established in 1867, the BSA today consists of over 4,500 members and is the second-largest chapter of the American Institute of Architects. The BSA is a nonprofit, professional-service organization with a mission of improving the lives of Boston residents by championing innovation in the built environment, with a focus on sustainability and social justice. Our partner organization, the BSA Foundation, supports the civic and public outreach of the architectural community. For more information, visit architects.org or architects.org/foundation.
