About the founder

Barbara Lewandowska AIA, the founder of Lewandowska Architect PLLC, begun her architectural career at IM Pei & Partners, where she was involved with the design of Kirklin Clinic in Birmingham, Federal Triangle government offi ce complex in Wash- ington D.C. In the following years she joined KPFC - KPF, where she had a primary role in the design of several of the firm’s nationally and internationally prominent projects,

which include First Hawaiian Center in Honolulu, Tokyo Europort Hotel, and a multi-use com- mercial & offi ce complex at 50 Avenue Montaigne in Paris. Subsequently she worked with SOM on the design of corporate headquarters for Investcorp, Vornado Realty, and NYSE expansion (not built) all in New York City.

Our philosophy

At Lewandowska Architect PLLC she continues her lifelong commitment to design excellence.

Every project establishes its own set of governing rules and requirements that evolve into intellectual concepts and aesthetic solutions, and that are not compromised by a preconceived style.

We believe in holistic approach to de- sign, which considers parts as well as the system to which they belong. Only then the project can integrate itself into the existing environment with an aim to improve lives.


Parallel to her professional practice Ms. Lewandowska taught Senior Design Studio, Thesis, “Materiality and Detailing", “Building Codes in Professional Practice” and other courses at Parsons the New School for Design (1995 - 2015.)

In addition, she taught Senior Design Studio and Thesis at Pratt Institute 2004-2006, and served on academic juries at Parsons, Pratt, New Jersey Institute of Technology and The City College of New York.

Looking back

When reflected on her career, she said that there were two events that changed her life: One was when she “moved” from behind a drawing board to the construction site, to oversee the construction of a nine story commercial building in the center of Paris.

This is when lines on the drawings became joints between materials in unlimited variations of colors and textures. The second was when she was invited to teach a design studio at Parsons. The change orders and RFIs became un- bound questions about design merit.
