He taught in the Masters of Science in Real Estate program at Columbia University from 2010 to 2015 with SOM partner Chris Cooper and Vishaan Chakrabarti.
[11] Kirchmann has designed more than 4,000 units of low-income housing that have been completed in New York City, including the redevelopment at Arverne View (formerly known as Ocean Village) in Rockaway, Queens, a region that was devastated by Hurricane Sandy in 2012.
[6] In 2015 Kirchmann designed the extensive façade renovation of the low income, 625-unit Marcus Garvey Village spread across nine city blocks, in the Brownsville section of Brooklyn.
Originally designed in 1973 by Kenneth Frampton, the project achieved notability at the time for its innovative urban planning approach to low-rise, high-density affordable housing.
[10] Prior to starting renovation work on 25 Mercer Street for what would eventually become a luxury condominium development in two historic cast-iron buildings in SoHo,[20] Kirchmann collaborated with British artist Shantell Martin, who installed drawings on two floors of the buildings, as well as light artist Matthew Schreiber, American Ballet Theatre dancer Kathryn Boren, and fashion photographer Nigel Barker.
