What Annum Architects (Formerly Ann Beha Architects) does

Annum Architects (formerly Ann Beha Architects) is a privately held, minority-owned architecture firm founded in 1980/1982 in Boston, Massachusetts, with a second office opened in Washington, DC in February 2026. The practice delivers comprehensive architectural services spanning new construction, renovation, adaptive reuse, historic preservation, campus and master planning, and interior design for academic, cultural, civic, and religious institutions. Its signature capability is the integration of contemporary design with preservation of historic fabric, supported by deep LEED certification expertise demonstrated by LEED Platinum (Harvard Divinity Swartz Hall, Cornell Law Academic Center), LEED Gold (Yale Humanities Quadrangle, Penn GSE, UPenn Music Building), and LEED Silver (Boston Engine 17 Firehouse, Springfield Tech, Cambridge Public Library) project outcomes. The client base is heavily skewed to elite higher education (Harvard, Yale, Penn, UChicago, Cornell, Bates, Colby, Lafayette, Phillips Academy, Brooks, Pomfret, Emma Willard, New England Conservatory) and major museums/cultural institutions (Museum of Fine Arts Boston, Smithsonian, Peabody Essex, Currier, Shelburne, Newberry, Mattatuck, Muskegon, Boston Athenaeum), with select civic (City of Boston) and federal (U.S. Department of State Embassy Athens) engagements. Revenue is generated through project-based professional service fees negotiated per engagement, with no publicly disclosed pricing tiers; work is secured via RFPs, design competitions, and direct commissions rather than productized pricing. The firm is led by President Philip Chen FAIA following a 2022 generational leadership transition, with founder Ann Beha FAIA continuing as Senior Collaborating Architect and a 2023 Yale Distinguished Visiting Professor appointment.
