Washington, DC, US



William is a recent graduate of the Architectural Association School of Architecture in London, U.K. where he received his Masters degree in Housing & Urbanism. While studying at the AA, William's thesis dissertation, "Circulatory Environments as a Method Towards Association," studied the under exploited potentials in circulation spaces within residential building typologies. While circulatory environments are perceived as subtractions from the efficiency of a building, three cases were explored where the difficulty in the morphological starting point, the circulation, could make greater use of highly articulated and highly differentiated circulatory environments. This becomes relevant when considering the associational qualities related to movement. Prior to studying at the AA, William earned a Bachelor of Science degree in Architecture from the Catholic University of America, in Washington D.C.

William approaches architecture and urbanism with a belief that they should be treated as a dialogue, which in turn can sharpen an agenda. Recent topics of William's studies and writing have been the evolving workplace urbanism, event led planning, adaptive housing for young professionals, and the relationship between universities and businesses within the context of a knowledge based economy.

William has a background in socially equitable and urban design which he gained though his employment with Bonstra Haresign Architects in Washington, D.C. During his time with BHA, William worked on projects in a multitude of sectors, engaging in the design and documentation of projects of various programs and typologies. His employment there was instrumental in gaining knowledge of not just architectural design, but the profession. Additionally, he has gained experience in sustainable environmental design though his participation in the United States Department of Energy's "Solar Decathlon." The competition challenges collegiate teams to design and build a zero energy home.
