VOITH & MACTAVISH ARCHITECTS is an architecture, preservation, planning, and interior design firm. Founded in 1988 with a commitment to the highest quality design and service, we believe that great architecture comes from innovation within the context of tradition. We have the flexibility to provide expert services in renovation, restoration, additions, new construction, and site development with a national reputation for an ability to work within significant architectural contexts in a knowledgeable and sympathetic manner. Partners Daniela Holt Voith, FAIA, and John Cluver, AIA, direct a staff of almost forty talented and dedicated professionals. Located in Center City Philadelphia, our office is a physical representation of how we work: One large, open room, it facilitates and symbolizes the collaboration and constant exchange of energy and ideas that is the basis of our creative process.
