Who  we are

Sewell/ Architecture PPLC is owned and operated by Michael Paul Sewell, an architect based in Washington DC.  Mike’s work is focused on the practice of residential architecture in and around Washington DC.

What makes us different

My work is characterized by a deep knowledge of local residential architecture and a unique sensitivity to site, program, and environment.  I aspire to create memorable modern architecture that looks to the future while acknowledging tradition.  My knowledge and background help me to  deliver cost-effective and memorable site specific design solutions. I am a LEED-accredited professional, and embed sustainability as a core value in my work.

Who we work with

Most of my work is for owner-occupants of residential properties, and my roots in the DMV give us me deep connections and relationships in the local design and construction industry.  My work is made possible because of great relationships with structural and mechanical engineers, contractors and tradespeople, permit expeditors, and local regulatory officials.


My professional work has included designs for commercial office buildings, cultural, academic, and research institutions, and diplomatic facilities for the US Department of State. This work has been recognized with multiple regional and national design awards.  I opened Sewell/ Architecture in 2009 after more than a decade of work as a senior designer with leading international practices including Kohn Pedersen Fox (KPF) and Skidmore Owings and Merrill (SOM).

Born in the Netherlands and raised in DC, I studied architecture at Tulane, and at Harvard University’s Graduate School of Design (GSD).  I returned to DC in 2005 to lead SOM’s renovation of the Smithsonian National Museum of American History. A committed educator, I have also taught design studios at Harvard, Tulane, Roger Williams, Northeastern, the Boston Architectural College, and Catholic University, and the University of Maryland

What we do for fun

When I’m not at the office or on a jobsite, I enjoy cycling, skiing, running, and ultimate frisbee. On weekends I am often found on the trails of Rock Creek Park with my family and dogs.
