Steven Weixler studied architecture at the University of Kentucky, and it was there he developed his interest in interior design. His background and literacy in architecture helped the firm and its clients smooth the transition from house to home. His role was instrumental in establishing an understanding of the clients’ needs and he translated those needs into the spatial and technical language required to meet them. His influence can be seen in all of the firm’s work, from the architectural detailing of an historic restoration to the integration of advanced electronics in a home theatre to state-of-the-art lighting, which is so critical to one’s perception of the built environment. His aesthetic influence and keen sense of spatial relationships continue under his partners’ direction. Mr. Weixler also was President of the Society Hill Civic Association and founding Chairman of the Central Delaware Advocacy Group, a coalition of representatives from fifteen civic associations that span the central Delaware waterfront in Philadelphia. He was a member of the International Association of Lighting Designers, the Philadelphia chapter of Classical America, and the Philadelphia Athenæum.
