He is the son of architect Henrik Wartiainen. After working for his father, he first founded Kai Wartiainen Architects in Helsinki.
Wartiainen was professor of urban planning at the Royal Institute of Technology in Stockholm, Sweden in 1997-2006. Then, between 2004 and 2010 he became a partner and Creative Director in Evata – at the time the largest architectural firm in Finland. He became creative director of Pöyry Architects between 2008-2011.
In 2000 he founded the Stockholm planning firm ajö´ tristess with architect Ingrid Reppen, though in 2011 it changed its name to arkitektur + development.
Among Wartiainen"s realised building designs include the High Technical Center (HTC), Ruoholahti, Helsinki (2001), the Grani Shopping Centre, Kauniainen (2001), Karkkila town hall and library (1991) and Itä-Pasila urban insertions (2005). In 1997 Wartiainen was selected to lead the research in defining the ecological criteria for Finland"s first eco-village, Eko-Viikki.
Together with a work group, he drew up the so-called PIMWAG criteria (the name was derived from the initials of the members), id est (that is) 5 factors to be taken into account in assessing the level of ecology of a scheme: pollution, the availability of natural resources, health, the biodiversity of nature, and nutrition.
He plots a historical line of development from the "full control" of autocrats to the "instrumental control" of what he terms expert dictatorship to the ultimate goal of the "out of control" of co-creation, and whereby professional urban design and planning expertise is ultimately replaced by urban management.
In addition to ecological issues, Wartiainen has also been a controversial champion of libertarianism and the so-called "innovation culture" typified by the internet, and criticises the inflexibility of the state-driven norms of urban planning practice.
