Troy A. Prosa


Troy’s interest in architecture began early on. At a young age, he kept busy by sketching, reading and learning about architecture – and he tried to never miss an episode of “This Old House” on PBS. Even when attending sleepovers at a friend’s house, the young teen would either set to tape record himself or call home to remind his parents to do so.

At age 15, Troy began designing and drawing projects for residential contractors, and his career path was cemented. His curious interest soon developed into a strong passion and his chosen profession.

Troy studied architecture at the University of Minnesota and became a licensed architect in Wisconsin. Between 1996 and 2002, Troy worked at the firm SSV in Minneapolis on office, educational and institutional projects, in addition to working on convents and multi-family homes. There, he worked under the direction of architect John Van Dyke. The pair developed a close working relationship that continues to this day at TAP Architecture.

Since 2002, his work has focused primarily on residential projects. Troy possesses extensive experience in custom home and renovation design, with a thorough background in cabinetry, furniture design and fabrication – both residential and institutional. His work has been featured in Homes by Architects, Luxury Home Tour, The Wall Street Journal-Mansion and various other publications.

Troy lives in Southwest Minneapolis with his wife and two young sons. When not designing, chances are he is biking on the many Minneapolis lake paths and city trails.

In Memoriam, John Van Dyke


With both deep sadness and profound gratitude, TAP Architecture honors the memory of John Van Dyke. He was more than one of our principals… he was a beloved mentor and a close friend.

John Van Dyke, known to many as ‘J’, was a 1962 graduate of the University of Minnesota (BArch). He established his own practice in 1978, working primarily as a consultant to other architectural firms, most notably on the design of the Riverplace project in Minneapolis. During this period, he aided his community by designing the new space for the Amery Public Library and the Arnell Memorial Animal Shelter. In 1989, he became a partner in the firm of SSV Architecture, Inc., where he worked in many fields, including residential, municipal government, and institutional work. After resigning from SSV in 2007, he joined TAP Architecture and was our principal, mentor, and friend through the final chapter of his 60-year architectural career. 

J’s gifts to the world extended far beyond the limits of architecture. He will be forever remembered for his encouraging words, wise insights, and kind heart.
