Elkus / Manfredi Architects is an architectural firm based in Boston, Massachusetts founded in 1988 by David Manfredi and the late Howard F. Elkus (1938–2017), both fellows of the American Institute of Architects. Its international projects include Sochi Grand Marina and the Galleria at Sowwah Square. In 2014–2015, the firm did lead preliminary design work on the abortive Boston bid for the 2024 Summer Olympics proposals.
