Ellenzweig is an architectural firm located in Boston, Massachusetts.  Since 1965, when the firm was founded, we have provided master planning, programming, feasibility study, in-house laboratory planning, and architectural design services to academic, institutional, and corporate clients.  Our projects include technically complex buildings for science research and teaching, medical and business education, and infrastructure - energy and chilled water plants, parking complexes, and transit facilities.

Initial commissions at the Massachusetts Institute of Technology (MIT) and Harvard University launched our firm’s continuing focus on academic and institutional facilities.  Our planning and design work with MIT has been on-going since 1965, and has included just about every type of academic facility found on a campus:  classrooms, laboratories, offices, libraries, housing, performance spaces, meeting and function rooms, energy buildings, and chilled water plants.  Our collaboration with Harvard University has continued for more than 30 years—from our first research laboratory project for the Department of Chemistry and Chemical Biology in 1973 to our present design of new departmental facilities for Earth and Planetary Sciences.

Based in Boston, our practice has become a national one.  Our clients include Stanford University, Yale University School of Medicine, University of Pennsylvania, The University of Chicago, Syracuse University, University of Florida, University of Vermont, University of Kentucky, Woods Hole Oceanographic Institution, Bowdoin College, Lafayette College, Dickinson College, Dartmouth College, Bryn Mawr College, Loyola University’s Stritch School of Medicine, University of Utah, The Children’s Hospital of Philadelphia, Eisai Research Institute, and many other teaching and research institutions across the country.
