Lars Peterssen, AIA, NCARB Principal / Architect
"Design works in mysterious ways. If Argentine architect Emilio Ambasz hadn’t accepted Milton Friedman’s invitation to speak at the Walker Art Center three decades ago, Lars might be living on Bainbridge Island in Seattle, designing the next generation of computers..."Read Bio
...At the time, Lars, who graduated magna cum laude from Carleton College with a degree in physics, was working on supercomputers at Control Data. When Ambasz spoke about the integration of architecture, landscape design, and product design, his ideas resonated with Lars on a profound intellectual level. Lars recognized that architecture, like science, includes an analytical approach to problem solving, only on a grander and infinitely more beautiful scale.
Lars brings this unique perspective to each of his projects. His designs bring warmth and texture to modern design, and he specializes in bringing together the very best of styles. His distinct residences and projects can be found in New York City, Deer Valley, California, Florida, Arizona and across the Midwest.
Lars is a founding principal of Peterssen/Keller. Lars has worked at Meyer, Scherer, and Rockcastle, The Cuningham Group and he was a founding partner of Domain Architecture & Design. Lars also taught at the University of Minnesota and was awarded the Frederick Mann Award for Disciplinary Service. Lars has had extensive business holdings in Russia, including restaurants and an import/export company.
Lars is a member of the AIA, NCARB certified, and a licensed architect in New York, Minnesota, North Dakota and Wisconsin. Lars has a master of architecture degree from the University of Minnesota, where he was honored with the AIA Henry Adams Medal for his accomplishments.

Gabriel Keller, Associate AIA Principal / Designer

...This experience is ultimately about designing a sense of place, and of home, that is uniquely individual to each of his clients and their richly divergent locales.
At the age of sixteen Gabriel lived abroad in Antwerp, Belgium, where he immersed himself in European culture, food, and football. After graduating with highest honors, Gabe headed east to Cornell University, one of the oldest architecture schools in the country. After spending three years in Ithaca and studying classical architecture and design in Rome, he was lured by the siren song of Soho.

Recognizing his true passion for residential design, Gabriel returned home to Minneapolis. At Domain Architecture & Design, he found a kindred spirit in colleague Lars Peterssen and the duo designed award-winning traditional and contemporary homes, lofts, and cabins for clients in the Twin Cities and around the country. Driven by a desire to refine his own architectural style, Gabriel cofounded Peterssen/Keller Architecture in 2009. His scope is national--with homes under design in New York to California--and his work has been extensively featured in numerous national and international publications.
Today, Gabriel's life has come full circle--just the way he designed it. With a solid footing in the local community and a thriving family, Gabriel sees Peterssen/Keller's location in Minneapolis as the perfect platform for their developing portfolio of bespoke homes located around the country.
Gabriel is an Associate member of the AIA, where he co-chairs the AIA MN Residential Architecture Committee, is a member of the Committee on Equity, Diversity and Inclusion, and is part of the Intercultural Leadership Program.
